Screen Shot 2017-04-11 at 4.02.17 PM.pngThe Internet Engineering Task Force (IETF) blew into Chicago for IETF 98, March 25-31. As has become customary, a full week of improving the internet kicked off with the IETF Hackathon, March 25-26. The hackathon one of the key elements of the IETF’s approach to combine running code and open source software with the specification of new and evolving internet standards.

 

IETF hackathons are free and open to everyone. The stated goals are to:

 

  • Advance the pace and relevance of IETF standards activities by bringing the speed and collaborative spirit of open source development into the IETF
  • Bring developers and young people into IETF and get them exposed to and interested in IETF

 

Attending the IETF meeting the following is encouraged but optional. One of the ways the hackathon meets it first goal is by participants sharing what they achieved and learned during the hackathon with the larger IETF community, both by presenting their result during working group sessions throughout the week and by demonstrating their work at the Bits-n-Bites reception on Thursday evening.

This hackathon saw 115 or more people sacrifice a weekend of admiring Chicago’s brilliant architecture to instead collaborate on code with colleagues from various companies,  standards organizations, open source communities, and universities. For about a third of the participants, this was their first IETF hackathon. For about a dozen, this was their first experience with the IETF period.

We had roughly 15 different projects, each of which was led by volunteers known as champions. Projects were shared in advance via the hackathon wiki, and when the doors opened at 8am Saturday, champions posted signs by their tables to help potential contributors locate teams they wished to join.

Despite jet lag from travel and the early start, teams worked late into the night Saturday, even after the last remnants of dinner had been cleared and the last beer had been consumed. Sunday folks started early again, ironing out bugs and coding up additional functionality right up until the time project presentations started at 2pm. Each team had 4 minutes to share what they had done, what they had learned, and how they moved IETF work forward.

An esteemed set of judges from the IETF community listened and asked clarifying questions after each presentation. Winners were then announced in the spirit of friendly competition. The winning teams were as follows:

 

  • (D)TLS - Best Overall, for their work on TLS 1.3 and the corresponding version of DTLS

Screen Shot 2017-04-11 at 3.53.03 PM.png

  • NETVC - Measure Twice Cut Once, for a proof of concept that will guide future specifications

For additional details on these and other projects, see the project presentations. Also noteworthy, and close to be selected as a winner for several of these categories, was the I2NSF project team, with participants from Sungkyunkwan University in South Korea, who traveled to Chicago to continue their award winning project from the IETF 97 Hackathon last year in Seoul.

 

FullSizeRender.jpgWinners were given first shot at a variety of swag contributed by the IETF secretariat and Google. Winning teams also received priority when it came to hackathon projects to feature at Bit-n-Bites Thursday evening.

The following teams took advance of this opportunity to share their work with the larger IETF community in a fun atmosphere.

 

  • AMT/Multicast
  • CAPPORT
  • WebRTC PSAP
  • (D)TLS



 

Special thanks to our sponsors, Ericsson and Mozilla, who answered the call in the final weeks before the hackathon to help the expenses involved with holding the hackathon.  And thanks as well to my employer, Cisco DevNet, who supports my efforts organizing the hackathons and provided t-shirts for all participants, including for the first time ever, women’s specific sizes!

If you missed you in Chicago, no worries, another chance to save the internet is just around the corner. We hope to see you at the IETF 99 Hackathon in Prague, July 15-16.

Screen Shot 2017-04-07 at 12.03.47 PM.pngOpen Networking Summit (ONS) was this week in Santa Clara, CA. The theme of the conference was “Open Networking - Harmonize, Harness, Consume.” We kicked things off with a hackathon, the first ever at ONS. Despite being announced late and limited to a single day due to a packed schedule, roughly 100 people dropped in at some point and around 50 rolled up their sleeves and really contributed to one of more project teams. We certainly got the conference off on the right foot as we immediately began harmonizing folks from different open source projects, harnessing the passion and talents of a skilled group of open source developers, then consuming large quantities of draft beer at the Open Source Community Reception immediately after the hackathon.

 

Teams

 

  • The largest group by far was focused on ONAP. The wiki and code became publicly available only Monday morning. This group left in mass to attend to the ONAP overview session Monday morning, then returned for what was essentially a demonstration of how to get started with an ONAP deployment in Rackspace with lots of Q&A. This is currently the only supported deployment model. Deployment to generic OpenStack is coming soon. A few people actually tied to deploy their own instance, worked through some issues, but reported back positive results.
  • There were a few small teams that worked on projects around OpenSwitch OPX, led by Dell/EMC.
  • Others worked on docs for OpenDaylight, OPNFV, and OpenSwitch.


Project Presentations


IMG_5572.JPG

  • ONAP Team: The ONAP wiki went live and code was made publicly available at 7am, hacking started at 9am. Following a general overview of ONAP offered as one of the conference tutorials, participants walked through getting started with ONAP, installing and running it using a number of VMs spun up within Rackspace. There were some “surprises” along the way, but most things worked well and whatever did not was quickly resolved with help of experts in room. End results, 20+ people had first experience with ONAP, have a better understanding of what it is, how it works, and what is required to get it up and running. As of today, ONAP runs on Rackspace only; however, the support for a generic OpenStack deployment is coming soon (weeks, not months).
  • OpenSwitch Team: Used the gRPC interface provided through the OpenSwitch open source network operating system (OPX) to configure VLANs as a proof of concept of what can be done.
  • OpenDaylight Docs Team: Updated OpenDaylight Unimgr developer guide and user guide to new template and made changes for the upcoming release - Carbon.
  • OpenSwitch Docs Team: Explored ways to make documentation interactive. Used Open Switch docs as a test project to demonstrate the potential benefit to open source docs in general.
  • DELL DevOps Infra Team: Integrated an app into this infrastructure, using Elastic Beats with ELK stack to deploy logging configuration to all the servers in the cluster and report back and collect within Elk Stack and display via Kibana.

 

Consensus and Next Steps

 

  • Participants enjoyed the hackathon and considered it a very valuable use of their time. Note that they had to miss out on other tutorial and Keynote sessions in order to free up time to participate in the hackathon. Plans are to have additional hackathons at future ONS and other Linux Foundation events. We hope to see you there!
  • Thanks to Cisco DevNet and Dell-EMC for their efforts in joining with the Linux Foundation to make this first ever hackathon a reality.

Screen Shot 2017-04-07 at 11.58.20 AM.png

FOSDEM 2017 is February 4-5, 2017 in Brussels Belgium. It is absolutely FREE to attend and registrations is not necessary.

 

FOSDEM is widely considered the premier open source conference in all of Europe. Its held every year at Université libre de Bruxelles in Belgium. FOSDEM is a free, non-commercial event, organized by the open source community for the open source community. The goal is to provide open source software developers and communities a place to meet to:

 

  • get in touch with other open source developers and projects
  • attend presentations on various topics by project leaders and committers
  • promote development and benefits of open source solutions

 

Core to the FOSDEM experience is the concept of devrooms. Devrooms are a place for teams to discuss, hack and publicly present the latest directions, lightning talks, news and discussions. Devrooms often exist for open source projects, but they can also be created for specific topics or areas of interest. This year Cisco DevNet is helping organize the SDN and NFV devroom. Here you will find sessions like Getting Started with OpenDaylight, Using OpenDaylight to Enable Advanced BGP Use Cases, FastDataStacks - A Platform for High Performance Applications Using FD.io, PNDA.io - Big Data Open Source Platform, and much more. You will also get the inside scoop on what it takes to run the network for FOSDEM and all the crazy ways in which 8000 open source developers stress a network.

 

Mark your calendars and join us at FOSDEM. I look forward to seeing you there!

The Internet Engineering Task Force (IETF) met in Seoul, South Korea this week. The meeting got off to a great start with the IETF Hackathon, November 12-13. The hackathon benefited from roughly 120 participants in Seoul, plus more than 20 remote participants. Work covered a broad range of IETF topics, and the results were both valuable and inspiring.

 

This was the 6th IETF Hackathon in a series that started in March of 2015 at IETF 92 with the following goals:

 

  1. Advance the pace and relevance of IETF work
  2. Attract young people and developers to the IETF

 

Confirmation of the second goal was evident from the start of the hackathon as a show of hands indicated this was the first IETF experience for a few dozen people and the first IETF Hackathon for many more. Evidence of first would need to wait until the results presentations at the end of the hackathon.

 

Not Your Typical Hackathon

 

Screen Shot 2016-11-17 at 5.46.34 PM.png

The IETF Hackathon is not a typical hackathon. Participants are motivated by a desire to improve the internet rather than prize money. The spirit it collaborative rather than competitive. Participation is free and attending the IETF meeting that follows is not required. Individuals volunteer to “champion” projects related to IETF work, and teams form around these champions. The list of projects for this hackathon where as follows:

 

  • ACTN
  • Capturing and analyzing network data features – Joy
  • COSE/JOSE
  • DNS/DPRIVE/DNSSEC/DANE
  • Interface to Network Security Functions (I2NSF) Framework
  • Interface to the Routing System(I2RS)
  • LoRaWAN Wireshark dissector
  • Multipath TCP
  • PCE
  • Service Function DevKit
  • SFC
  • TLS 1.3
  • YANG/NETCONF/RESTCONF

 

Screen Shot 2016-11-17 at 5.58.36 PM.png

One of the ways the hackathon increases the pace and relevance of IETF work is through running code. Implementing evolving standards and producing running code validates the standards and highlights things that may be missing, wrong, or ambiguous in draft versions of these standards. Better still is if the code is open source, in which case viewing and sharing the source code aids in understanding of a standard, makes it easier to use, and promotes its adoption. Open source projects that featured prominently in the hackathon included OpenDaylight, ONOS, VPP, Joy, and many others. The list of hackathon projects and a brief description is accessible on the wiki.

 

Winners and Winners

 

Despite the lack of big prize money, participants engage in friendly competition for bragging rights and first shot at a set of gadgets donated by sponsors. Teams present their results to a panel of judges who have the difficult job of choosing winners. The winners and categories this time were as follows:

 

  • Best Overall – Multipath TCP team

This team was a composed of a set of professors and students from Ecole Polytechnique de Louvain in Belgium, some of whom travelled to Seoul while others participated remotely from Belgium. This gave the team the benefit of working in shifts around the clock. You can read their story and results here.

Screen Shot 2016-11-17 at 5.39.49 PM.png

 

  • Best Input to a Working Group - ACTN team

The Abstraction and Control of Transport Networks (ACTN) team produced important feedback for both the Traffic Engineering Architecture and Signaling (TEAS) working group and the Interface to Routing System (I2RS) working group, and their code will become an upstream contribution to the ONOS project.

actn-team.jpg

 

  • Best Group Work - I2NSF team

The Interface to Network Security Function (I2NSF) team, powered by energetic professors and students from Sungkyunkwan University in South Korea, used RESTCONF and NETCONF together with YANG data models to implement network security services using OpenDaylight and mininet. In doing so, they validated the approach defined by the I2NSF working group.

  • Best New Work to IETF - Service Function Dev Kit team and SFC team

The award was given to two separate teams that both did work related to Service Function Chaining (SFC). The first added support for Network Service Headers (NSH) to VPP and the Service Function Dev Kit, thus making it easier for developers to integrate with service function classifiers and forwarders.

Screen Shot 2016-11-17 at 6.06.51 PM.png

The latter demonstrated hierarchical SFC with flow stateful classifier using OpenDaylight and intent based SFC with ONOS.

Screen Shot 2016-11-17 at 6.08.28 PM.png

 

Of course other teams had fantastic achievements as well. All project presentations have been uploaded here, and a recording of the project presentations and awards is available here. One pervasive theme was the continued work involving YANG, NETCONF, and RESTCONF aimed at improving operations through automation. Benoit Claise, one of the Operations and Management Area Directors, posted this summary. Vladimir Vassilev, from TransPacket, travelled from Oslo to Seoul for the sole purpose of participating in the hackathon. When asked why he shared the following:

 

You get all these people with passion for what they are doing trying to accomplish something in these two days that will make the world better in a very practical way. It creates a unique atmosphere for creativity. Free to participate, getting the chance to interact with all the great minds there and share ideas makes the Hackathon a unique event. Those are the same principles the IETF is built on. I have participated twice and both have proven to be very successful. I intend to continue with that. On the practical side the event is held during the weekend which allows engineers from smaller companies that do not have dedicated standardization work focus to participate.

 

TransPacket has taken some bold decisions that have brought benefit to the company and in the same time to the open source community and the IETF. We have been one of the fastest implementors of YANG/NETCONF drafts and standards … I think that the importance of the Hackathon event will grow with the tendency of increased adoption of YANG/NETCONF by smaller companies.

 

Want to Join the next IETF Hackathon?

 

The next IETF Hackathon will be at IETF 98 in Chicago, March 25-26, 2017. As always, participation is free and open to everyone. The IETF hackathon is a great way to experience firsthand the far reaching work the IETF does and the people that make it happen. It is an event that invites open source communities to join the IETF and other standards organizations to improve the functionality, security, and operability of the internet we all know and love. The keep up to date with all things related to past, present, and future hackathons, including the opening of registration for the IETF 98 Hackathon, subscribe to hackathon@ietf.org.

hack-entry.jpg

The IETF Hackathon in Berlin, held July 16-17, was the biggest and most impactful IETF Hackathon to date. A record 158 participants registered, and even more showed up over the course of the weekend to work on more than 20 projects spanning at least 15 different technologies. This hackathon was the first IETF hackathon for almost half of the participants, and it was the first IETF experience or any sort for more than 25 individuals. This speaks very well of how the hackathon is doing in terms of meeting its objective of introducing more people to the IETF and making their first experience a positive one.

 

Goals of IETF Hackathon

  • Advance pace and relevance of IETF standards activities by bringing the speed and collaborative spirit of open source development into the IETF (e.g. targeted standards areas where ideas are flushed out, sample code is produced, and useful utilities are developed)
  • Bring developers and young people into IETF and get them exposed to and interested in IETF

 

room.jpg

 

This was the 5th time a hackathon was held in conjunction with an IETF meeting, and as done previously, it was held over a weekend that marked the start of a full week of IETF activities. By the time the doors officially opened at 9am on Saturday, the room was already over half full with a mix of project champions eager to share posters describing their projects and participants seeking the best match for their interests and skills.

 

poster1.jpg

 

Project posters were a new component of the hackathon. They were used in place of the short presentations on each project that typically occurred at the start of the hackathon. The reason being that even when presentations are restricted to no more than 5 minutes, having 20 or more of them simply eats up to much valuable time that could have been spent hacking. Posters ranged from professional looking masterpieces to a few words scribbled haphazardly on a flip chart, with all serving the intended purpose, and ad-hoc Q&A providing any necessary clarifications. An unofficial survey of participants validated the hypothesis that the posters were indeed a welcome change.

posters.jpgposter2.jpgposter-min.jpgposters3.jpg

 

 

 

 

 

 

 

 

 

 

 

Teams formed very quickly, and additional participants were welcomed as they trickled in the rest of Saturday and even Sunday morning. A competitive spirit was clearly evident but the collaborative spirit aimed at moving IETF work forward with great speed, quality, and relevance through running code and open source software was much greater. The teams worked tirelessly, with a coffee machine, lunch, cookies, , dinner, and beer providing more than adequate fuel and incentive to remain on task. Many participants finally agreed to leave Saturday at 10:15pm to allow hotel staff to lock up and go home. When the doors reopened Sunday morning, many got right back to work even before the officially advertised 9am start time.

 

By early Sunday afternoon, teams switched gears a bit to pull together brief presentations that answered these questions:

  1. What problem you are solving?
  2. How do you plan to solve it?
  3. What did you achieve, highlighting benefits to IETF work and communities of interest?

 

The presentations were not only for fellow hackers in the room and for judges with the difficult task of selecting winners, but for streaming live and recording for the benefit of those not able to join the actual event. And the winners were:

 

Best Overall

  • ILA - IPv6 Identifier Locator Addressing
    • Implementing draft-herbert-nvo3-ila-02
    • Data plane method to implement network virtualization without encapsulation and its related overhead
    • Implemented ILA as VPP plugin
    • Interop between VPP in FD.io and Linux kernel space fast data path in ioVisor
    • winners-il.JPG

It was great to see so many of you spending time at the Cisco booth at the Red Hat Summit in San Francisco last week. It was both interesting and telling to see the huge increase in content and focus on networking in general and on Network Function Virtualization (NFV) more specifically. Noteworthy presentations included:

 

Red Hat NFV.JPG

Red Hat NFV Solution Overview

    • OPNFV, bridge between Telco and open source community (ETSI and Linux/OpenStack/OpenDaylight)
    • RedHat APEX, NFV community project based on RDO - free
    • RedHat NFV Solution as commercial solution - paid subscription

 

OpenStack, SDN, NFV

    • Red Hat OpenStack Platform 8, based on Liberty and REL7
    • Red Hat Neutron focus today is with OVS, but OpenDaylight on roadmap
    • Putting the entire stack together
      • OpenStack->libvert->DPDK->OVS->QEMU/KVM->LinuxDPDK.JPG
      • DPDK enabled version of OvS is new with OpenStack Platform 8
      • Uses VXLAN by default, though GRE is supported
      • Network namespaces used for tenant with overlapping IP address spaces
      • dnsmask operating DHCP per tenant
      • DPDK, set of libraries that provide user space networking implementation within an application or VM instead of using the kernel networking stack

 

Ward Open Source.JPGIn his keynote session, Dave Ward described the massive transformation in networking infrastructure and the goal of enabling the no stack developer, i.e. the network details are abstracted from the application developer, and the functionality and services the application needs are accessible through simple APIs. Open source is a driving and defining force in this transformation. Open source projects and communities are driving the innovation in the networking, container, and cloud industries.

 

With so much great content vying for your attention, it was rewarding to a good turnout for the Cisco DevNet presentations on OpenStack and OpenDaylight in the mini theater. In case you missed them, a brief summary and the slides are available here.

 

openstack.pngGetting Started with OpenStack, Slides

Speaker: Charles Eckel, Open Source Developer Evangelist, Cisco DevNet

Abstract: Hearing a lot about OpenStack and want to check it out for yourself? See how quick and easy it is to install and start using OpenStack using containers running within a VM on your own laptop. Familiarize yourself with the environment. Learn to use the Horizon (GUI) and the CLI to view and operate an OpenStack cloud, both as a cloud administrator as well as a tenant/user of the cloud.

IMG_4389.JPGThe International Multimedia Telecommunications Consortium (IMTC) held its 21st Annual Multimedia Products and Services Interoperability Testing Event, SuperOp! 2016, at Loews Royal Pacific Resort in Orlando, Florida, May 14-20, 2016.

Okay, now to the results.


The SIP Interconnect Activity Group testing drew at least 16 product teams from companies including Blue Jeans Networks, Cisco Systems, Huawei, Intel, Pexip, Polycom, Sonus Networks , Sorenson Communications, Spirent Communications, Vidyo, and Wipro. Testing focused on key aspects of videoconferencing/telepresence interoperability, with the IMTC SIP Interconnect best practices and associated test cases documents providing a framework within which to test and report results. Interworking across implementations was quite broad, extending beyond that covered within the best practice documents, including SIP/WebRTC interworking via gateways provided by several participants.

 

Most of the companies participating had been to previous SuperOp events, and while there were many new faces, representatives from most companies included a mix of seasoned SuperOp attendees along with the newcomers. As a result, the level of interworking and the sophistication of the test scenarios was more advanced than in previous years. New interoperability issues were identified, some of which were resolved during the week with corresponding changes being fed back into the best practices and test cases documents. Others challenges require more consideration and will be addressed by future SIP Interconnect AG member meetings.

 

The group recently published an official update to its SIP Video Profile Best Practice, IMTC1015. Official publications of the groups Role Base Video Best Practice and SIP Security Best Practice are planned within the next year. New participants, findings, and questions are welcome and encouraged. To get started, visit the IMTC member portal and subscribe to the SIP Interconnect mailer.

Screen Shot 2016-05-06 at 9.49.21 AM.pngThe International Multimedia Telecommunications Consortium (IMTC) is all set to host the 21st Annual IMTC Multimedia Products and Services Interoperability Testing Event, SuperOp! 2016, taking place at Loews Royal Pacific Resort in Orlando, Florida, May 14-20, 2016.

 

Testing includes communication technologies such as WebRTC, UC SDN, H.26x SVC, SIP over IPv6, SIP and H.323 Video Conferencing, Telepresence/TIP, MPEG-DASH streaming, IMS, VoLTE, RCS, Video over LTE, and many others. The IMTC is not a standards body; rather, it produces best practices outlining how to use existing standards to produce solutions that interwork well with those produced by other vendors. It also provides test case document that structure testing at the event and provide quantitative results of the level of interoperability among with implementation represented at the event.

 

One of the IMTC activity groups that participates actively each year in this event is the SIP Interconnect AG. This group provides a forum for IMTC member companies to collaborate and pool resources on issues and extensions to enterprise communication applications that are based on the IETF's RFC 3261, SIP: Session Initiation Protocol. With its best practices documents providing a shared foundation, the group identifies and tackles challenges and opportunities with interoperability, operation, and integration of SIP based applications with emerging communication and networking technologies.

 

The main activities of the group are to:

Screen Shot 2016-05-06 at 9.44.42 AM.png

        • Organize interoperability test efforts (both virtual and face-to-face)
      • Provide a forum for members to agree on an overall SIP profile for communication applications, including where it involves interconnecting with other application and network technologies (e.g. WebRTC, SDN, IPv6)
      • Educate members on recent developments in SIP standards and market evolution

Rome was not built in a day, and neither was a complete reference implementation of the MEF's LSO architecture. However, at the Euro16 Hackathon in Rome last week, a group of talented developers made great progress in that direction. For those not intimately familiar with MEF, the LSO architecture, or the corresponding open source initiatives, here is a bit of background.

 

MEF, a standards organization with its roots in carrier ethernet, noticed that network service orchestration is the key pain point of service providers today.  MEF targeted this by defining Lifecycle Service Orchestration (LSO), an umbrella architecture with APIs enabling agile, assured and orchestrated network services worldwide. It includes inter-provider interfaces ("east/west") as well as intra-provider ("north/south") interfaces.

lso.png

MEF refers to the network powered by LSO as the “Third Network". The Third Network is a revolution in service provider networking. It combines Internet agility and ubiquity with service assurance, offers unprecedented levels of user control of the network, and delivers dynamic, on-demand service experience. It is expected that other SDOs will implement parts of this architecture. Toward that goal, MEF is working with ETSI-NFV, ONF, TMF and others, and it has launched a set of open source initiatives through which such as OpenDaylight, OpenStack, and OPNFV are being enhanced and applied to create a reference implementation of the LSO architecture.

 

It all started last November, when Cisco DevNet helped MEF take a bold step into uncharted territory, holding its first ever hackathon. The primary goal was to bring together the key subject matter experts defining LSO with the developers creating industry changing open source projects for the mutual benefit of both. The focus was the LSO Presto interface, a"north-south" interface for network resource provisioning. Among other things, teams worked to add support for this interface to OpenDaylight. A complete a summary of this industry changing event can be found here: LSO Hackathon debut at GEN15.

 

The impact of that first hackathon extended well beyond the code produced over the course of that week. Participation by open source experts from a mix of long time MEF member companies and non-member companies caused the MEF to make its work-in-progress specifications and corresponding APIs available to non member companies. It also prompted MEF to consider how it treats contributions in the form of code rather than written documents and specifications. More publicly, it inspired the creation of two new projects within MEF, OpenLSO and OpenCS, both aimed at the production of open source reference implementations aligned with MEF architectures and specifications.

 

open-initiatives.png

Last but certainly not least, it led to MEF working with Cisco DevNet to plan a second LSO hackathon, the Euro16 Hackathon, as part of the recent Q2 MEF meeting in Rome. The Euro16 hackathon raised the bar early in the planning stages, challenging teams to work not only adding support for LSO Presto as they did during previous hackathon, but also on LSO Sonata, dealing with ordering and serviceability across service providers.

 

As with the previous hackathon, registration was free and open to everyone. Registrants included individuals from 16 different companies. Most participants met together in Rome, while others engaged effectively from remote locations. To get things going, organizers provided some background on the LSO architecture. Next, each team gave a brief presentation of their goals and objectives, including the projects and products they intended to use and how their proposed work fit into the LSO architecture. Party lines blurred almost immediately as participants identified and jumped at the chance to work across multiple teams with new colleagues and technologies. This excitement and energy continued for the next two and half days, as participants worked feverishly to make the most of the opportunity at hand. The results were astounding, exceeding all expectations of the event organizers and the participants themselves.

Screen Shot 2016-05-05 at 4.20.12 PM.pngOne team, with members from Cisco, HPE, Amartus, Microsemi, and Ericsson, worked on adding support for the Presto interface to OpenDaylight. This work was done within the context of the UniMgr project and running MEF's Network Resource Provisioning (NRP) UML model through the xmi2yang tools being defined by the ONF Eagle project to produce a YANG model that is then used to generate code for the Presto interface within OpenDaylight. The team also started work on Cisco IOS-XR, Microsemi, and Tail-f NETCONF interface activation drivers to enable OpenDaylight to configure the underlying network. Their work uncovered issues with the NRP model, the ONF Core Model core model on which it is based, and the xmi2yang tool coming out of the ONF Eagle project. It highlighted that code generation from the resulting YANG models is not straightforward, partly because ONF Core models and derived MEF YANG models are information models and code generation requires data models. Here we see a very important outcome of the hackathon, providing a reality check to potential approaches and shining a spotlight on important details that might otherwise get glossed over.

euro16-participants.jpg

Working closely with this team were folks from Gigaspaces. They used the northbound interface of the Cloudify open source orchestrator as a sample LSO Legato interface implementation, and implemented the Presto forwarding constructs to communicate with the OpenDaylight UniMgr implementation under development by the previous team. In doing so, they identified gaps in the Legato inputs for ordering. They also pointed out that support at the Presto interface today is layer 2 only and that MEF needs to add support for layer 3 to its forwarding constructs.

 

Another team, compromised primarily of participants from long time MEF member companies (e.g. AT&T, Ciena, CableLabs, Ericsson), broke new ground for the hackathon, tackling ordering and serviceability between service providers as defined by the Sonata interface. This team used AT&T’s internal API to simulate taking an order from a customer, then used an experimental version of the Sonata API to communicate the order details between service providers. In the process they discovered some redundancy/duplicate fields in the ordering API, (e.g. customer address fields repeated in multiple places). The receiving SP process the order and configured the underlying network accordingly using BluePlanet with the ONOS controllers and EdgeCore switches. Here we see the hackathon identifying gaps and issues in the interface specs at the time these specs are being produced.

 

Yet another team worked with Enterprise CORD (Central Office Re-architected as a DataCenter), or E-CORD. E-CORD makes heavy use of open source, most notably, XOS and ONOS. Through close interaction with other participants during the event, the E-CORD team arrived at a redesigned architecture that is more appropriate for LSO. The new architecture will replace what they brought to the hackathon and be used for future work and hackathons. This demonstrates the tremendous value of the hackathon to help identify and address issues early. They also started down the path of implementing the Presto interface via the evolving NRP API.

 

Overall, the hackathon was viewed by all involved as a huge success. Of course there were things that could have been done better, but the participants agreed that the time spent preparing for and participating in the hackathon were extremely valuable and in productive. Stay tuned for announcements and news regarding the next in the LSO hackathon series, most likely as part of MEF16 in early November in Baltimore-Washington.

The IETF 95 Hackathon in Buenos Aires kicked off what was both the first and an extremely rewarding trip by the IETF community to South America. Roughy 100 participants, a record 10% of the total IETF meeting attendees, arrived early in Buenos Aires to put their talents to use tackling a diverse set of projects aimed at improving the internet we rely on every day.

 

The list of projects and teams included many familiar faces as well as a refreshing set of new participants and challenges. This was the first hackathon for about of the third or the participants, with over a dozen attending their first IETF meeting ever. Many first timers were from the host country, including from Buenos Aires and Mendoza, but there were two from Africa and others some Europe and the U.S. as well. Check out this story shared by one IETF and IETF hackathon first timer (https://communities.cisco.com/community/developer/opensource/blog/2016/04/25/first-timer-at-ietf-and-ietf-hackathon-shares-his-story).

 

Screen Shot 2016-04-26 at 2.21.44 AM.pngOther notable firsts for this hackathon were:

Charles Eckel, from Cisco DevNet, continues to run the hackathon in his role as hackathon chair and welcomes Barry Leiba, from Huawei as a appreciated and valued hackathon co-chair.

 

As with previous hackathons, participants worked cooperatively and tirelessly, producing fantastic results. Each team summarized their achievements in a brief presentation to judges and their peers. Tops honors and prizes were awarded for especially brilliant accomplishments, includes those of the FD.io/VPP team, the TLS 1.3 team (see story at https://www.ietf.org/blog/2016/04/ietf-hackathon-getting-tls-1-3-working-in-the-browser/), and the network-based network analytics team. Some teams demoed their work at Bits-n-Bites, including the NETCONF/YANG, I2RS, OpenDaylight teams, DNS/DNSSEC/DANE/DNS-over-(D)TLS teams, and the IBNEMO team. All the presentations and results are available via the proceedings page (https://www.ietf.org/proceedings/95/hackathon.html).

IETF 95 Hackathon

Authored by: Agustín Formoso

TL;DR

Great f2f meeting, worth attending. Get to know new people coding similar stuff that you might be coding. Get to feel the IETF spirit.

Still, I think it needs some intermediate level between high-barrier-and-focused, and low-barrier-but-unfocused groups.

First impressions

The basics

Essential things for the hackathon to feel comfortable were there: the physical space for all the participants, food and drinks (actually there were some pretty good meals and snacks), and enough power outlets to charge all of our nerdy devices.

One thing that could had been of use are additional elements for sprint planning such as post-its, big papers to set up sprint backlogs, and some paper and pens to sketch and communicate with other strange-language-speaking group mate.

The groups

At the kickoff, the group champions explained what each group is about and what the main objective is. As a first timer, looking for a suitable group to work with during 2 days was a critical point. My previous experience with the hackathon was literally none, as I had no relation with any work in progress so far. I had to find a group which topic was of interest to me and which I had at least some vague concept about the technologies involved. Fortunately, I ended up in a group which required no previous experience with, no specific tools to do what was planned, just my laptop and my will to solve a problem. The problem was to find any metrics that helped discover anomalies or patterns in a dataset of traceroutes, it was a cool project and I enjoyed being the two days coding stuff for it. Besides, you get to feel the nice IETF spirit of building things for a better Internet.

The ending

The group deliverables

Probably as the group I ended up in was very generic and the entry barrier was pretty low, setting specific deliverables for the 2 day sprint was difficult. Other groups had more specific tasks to accomplish, such as building features for a YANG modelling application or implementing TLS 1.3 in a Firefox browser. I guess that by following some of the groups closer and collaborating remotely prior to the hackathon might end up in getting the most out of the hackathon, as in that case the hackathon would just be a team f2f meeting, without the hassles of setting up development environments, getting to learn new concepts, or new technologies entirely (nor was my case, but I easily see that situation as a very common scenario as IETF hackathons get more popular).

I still think that the hackathon should consider having low, intermediate, and high entry barrier groups. There's room to set an intermediate level in each hackathon where the group would require some things such as tools (virtual machines, IDEs) and some follow up (probably in the order of weeks time). In that case I think a better and more focused deliverable might be reached. In this consideration, the low entry barrier groups should approach newcomers with no experience or contact with the IETF hackathon, and the high entry barrier group should approach the usual hackathon participants.

Further work

The IETF hasn't finished yet and I think is a very good instance to get to know new people and establish links to motivate future work. The coding done in the group I was part of is of special interest to me and hope that some months from now we have a nice tool to analyze network graphs which benefits our champion (Pål) and the rest of us.
