SuperOp! 2017 occurred May 13-19 in beautiful Prague. SuperOp! is an annual event hosted by the International Multimedia Telecommunications Consortium (IMTC) to promote interoperability of products from companies that provide multimedia telecommunications solutions.  Software developers, solution architects, networking experts, and quality assurance engineers from leading companies in the video communications and collaboration space met in Prague for a week of focused testing. Participants represented 16 different product teams from companies such as BlueJeans, Cisco, Intel, Pexip, Polycom, Sonus, Spirent, and Vidyo.


The IMTC SIP best practices and associated test cases, produced by IMTC’s SIP Interconnect Activity Group, provided a framework within which to test. However, interworking among teams was very broad, going above and beyond that described in the best practice documents. Call scenarios included point-to-point, point to multi-point, and cascaded multi-point conferences. Functionality tested included:


  • H.264-AVC/SVC/HEVC video
  • G.7xx and Opus audio
  • IPv4 and IPv6 for signaling and for media
  • Asymmetric negotiation of bandwidth and H.264 capabilities
  • RTCP feedback/AVPF (RFC 4585 and RFC 5104)
  • SIP/H.323 interworking
  • H.245 interworking for DTMF
  • Role based video for main video vs. content sharing
  • Bandwidth allocation for audio vs. main video vs. content sharing
  • BFCP via UDP for floor control for content sharing
  • BFCP/H.239 interworking
  • H.224 for far end camera control
  • Hold/resume with the context of point to point and multipoint calls
  • TLS signaling, including TLS 1.0, 1.1, and 1.2
  • SRTP media encryption negotiated via SDES
  • Negotiation and use of AES and AES GCM ciphers


BFCP over UDP for floor control for content sharing is now supported by all implementations. There are of course still some issues with various scenarios, but with RFC4582bis nearly complete, it is great to see nearly ubiquitous support. Test scenarios were expanded this year to include things such as negative testing, e.g. refusing to grant the floor when requested. TLS for SIP signaling and SRTP for media was supported by all implementations as well. This is great news and should lead to an increase of secure deployments in the near future. Another important accomplishment to help with security was identifying and fixing an issue with libsrtp, which is an open source package that provides an implementation of the Secure Real-time Transport Protocol (SRTP), the Universal Security Transform (UST), and a supporting cryptographic kernel, and is used within many Cisco and non-Cisco communication and collaboration products. IPv6 was supported and proven to work with the majority of implementations, too.


Participating teams found the event and the corresponding testing to be extremely valuable. By the 4th day of testing over 100 bugs had been identified. Some had already been fixed and verified while others required further investigation and testing. This early detection and addressing of bugs before they get deployed in the field and impact customers is a huge return on investment that prompts teams to return each year to take advantage of the opportunity to test their bleeding edge software with those of their partners, peers, and competitors in the market.


One fun and impressive activity near the end of SuperOp! each year is SuperConnect, the joining of everything being tested at SuperOp into one giant conference. Endpoints from vendors call into conferences hosted on Multipoint Control Units (MCUs) from different vendors, then these MCUs are cascaded together to form one uber conference.



In terms of things that can be improved for next time, self signed certificates were used in many cases and no certificates at all in others because there was no infrastructure in place to facilitate the distribution of certificates. ICE support and testing was very limited with only a few implementations at the event. The setup required to realistically test interesting scenarios was a limiting factor. Several participants expressed a desire to focus more on this next time. And while WebRTC to SIP interworking was tested to some extent within vendors' own products, it would have very helpful and valuable for everyone involved if some developers from WebRTC enabled browsers were present.


Interoperability is a moving and evolving target that is never complete. You can bet that after a well deserved rest, vacation, and/or return trip home, participants will start planning and anxiously anticipating the next SuperOp!


Euro17 LSO Hackathon Recap

Posted by eckelcu May 2, 2017

We just completed the Euro17 LSO Hackathon, the 4th in a series of events within MEF accelerating the standardization and adoption of MEF’s LSO Architecture. The LSO Architecture enables Lifecycle Service Orchestration, or LSO, an agile approach to automating network service lifecycles for coordinated management and control across all network domains responsible for delivering an end-to-end connectivity service (e.g., carrier ethernet, IP VPN, MPLS, etc.).


The LSO Hackathons encourage the creation and enhancement of reference implementations that use the APIs and interfaces being defined within MEF. The outputs of the hackathon include for the following:


  • validation of evolving APIs/standards
  • feedback into MEF technical committees
  • creation of software defined networking (SDN) controller plugins, interfaces to network orchestration solutions, etc.


They also promote collaboration across related standards development organizations (SDOs), such as IETF and TM Forum, and with open source communities, such as OpenDaylight, OpenStack, PNDA, etc. Benefits of this collaboration include:


  • increased awareness, open discussions
  • support for LSO APIs in relevant open source projects
  • more running code, e.g. sample code, utilities, test tools


The Euro17 Hackathon was April 24-26 in Frankfurt, Germany, in conjunction with MEF’s Q2 Member Meeting. Contrary to what you might think when you hear the word hackathon, LSO Hackathons are collaborative, featuring friendly competition. They are meant to break down silos, connect people from different companies and technical disciplines, and facilitate sharing perspectives, tips, and ideas. Participants have a common goal, to increase the pace and quality of LSO APIs and implementations. The hackathon is open to everyone, not just MEF member companies, and participation is free.


Participants at the Euro17 hackathon rallied around three main projects.


LSO Sonata Release 1 (kickoff presentation)






LSO Presto Release 1 (kickoff presentation)

  • Project Lead: Bartosz Michalik
  • OpenCS Packet WAN OpenDaylight Unimgr
    • Driver mechanism
    • Drivers
    • Presto northbound to SP apps
    • Code in Github:






LSO Analytics via PNDA (kickoff presentation)

  • Project Lead: Donald Hunter
  • OpenDaylight as producer (Kafka producer)
  • OpenStack as producer
  • Cisco ASR 9K as producer
  • Sample app consuming PNDA data


The teams worked extremely well together, kicking things off Monday, continuing through Tuesday, and wrapping up in time to present their results to fellow hackathon participants and the MEF community at large late afternoon Wednesday.

The results presentations covered the following:


  • Recap of problem being solved and plan to solve it
  • What was actually accomplished?
  • Lessons learned, feedback for technical committees, and next steps










The LSO Sonata Release 1 team consisted of a mix of local and remote. Local participation is encouraged to get the most of the hackathon, but these team proved that remote participation can work well with the right mix of participants. Companies involved included AT&T, TI Sparkle, and Cataworx.  A prototype version of Sonata serviceability and ordering APIs were used to simulate a customer placing an order and multiple service providers exchanging information about that order. Information obtained from the ordering APIs was mapped internally by implementations through the Legato level to ultimately interact with OpenDaylight via Presto API to activate a connectivity service ordered by a customer.



A subproject within the team involved the creation of a simple service that exposed a subset for the Sonata API, which when triggered, mapped Sonata requests through the Legato interface level and it into corresponding Presto requests. Following the hackathon, the plan is to open source this code and have an instance running in MEFnet that is enhanced to support a larger set of APIs over time.



The LSO Presto Release 1 team used the latest Presto API defined by the Network Resource Provisioning (NRP) project within MEF and added support for this API to OpenDaylight Unimgr. This was used as the basis for supporting the Presto API interaction by the LSO Sonata R1 team. The team also enhanced the Unimgr driver framework that facilitates the definition of multiple different network element drivers for interworking with equipment from different vendors and open source projects. They also created a template to make the creation of new drivers more straightforward. The code developed will be contributed upstream to OpenDaylight as part of the Nitrogen release.



The LSO Analytics via PNDA project worked on building some big data analytics for LSO deployments using PNDA, an open source platform for network data analytics. The first goal was to collect a lot of data. This was accomplished by collecting data from syslogs from Cisco ASR9Ks hosted within MEFnet using logstash, and from interface counters and frame delay measurements available via OpenDaylight. This information was ingested by PNDA as live data feeds from which time series graphs were generated. While the team did not achieve their ultimate goal of creating a closed loop system that made real time changes to the network based on result of analysis of the data, they made it clear that such a system could be realized in the future.

All the project presentations and recordings of the kickoff and wrap-up from the hackathon are available on the agenda page of the Euro17 LSO Hackathon wiki.



Having survived the hackathon and accomplished great things, the participants took to the streets of Frankfurt for some well-deserved celebration.


Thanks to our sponsors for the Euro17 hackathon, without whom all this great work would not have happened. As you might expect, they are already looking forward to the next hackathon at MEF17, November 13-15 in Orlando, Florida. We hope you join us there.

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.

Screen Shot 2017-04-11 at 4.00.43 PM.png


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.

Screen Shot 2017-04-12 at 12.43.29 PM.png

Screen Shot 2017-04-12 at 12.43.11 PM.png


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

Screen Shot 2017-04-11 at 3.54.09 PM.png

  • CAPPORT - Best Kickstart, for a project that kicked new energy into a working group that had stalled

Screen Shot 2017-04-11 at 3.58.31 PM.png

  • WebRTC PSAP - Best Students, for a new project from professors and students at the Illinois Institute of Technology (IIT)

Screen Shot 2017-04-11 at 3.54.59 PM.png

  • LoRaWAN - Best Newcomers, for a project that benefited from significant contribution from first time IETFers

  • AMT-Multicast - Most Remote Participant, with a team member participating remotely from Mauritius

Screen Shot 2017-04-11 at 3.57.24 PM.png

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
  • (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!



Last but certainly not least, thanks to Alissa Cooper and Jari Arkko, the incoming and outgoing IETF chairs, who are both big supporters of the hackathon and have been instrumental in bringing it to the IETF. Be sure to check out their summary of IETF 98.

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.




  • 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


  • 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.

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
  • 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


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.



  • 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.


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




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.




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.













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

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 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.

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.

Need more background on the event? Check out the this blogpost leading up to it, Get Ready to Interoperate at IMTC SuperOp 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
