Cisco Kinetic EFM Frequently Asked Questions (FAQ)

1. What is Cisco Kinetic?

Cisco Kinetic is an IoT data fabric — a distributed system of software designed specifically to extract, compute, and move data from the things that make up the IoT to the various applications where it can provide value. The core Cisco Kinetic platform includes three software modules that provide the functionality customers need to extract, compute, and move data to achieve desired business outcomes.

  • Gateway Management Module
  • Edge & Fog Processing Module
  • Data Control Module

 

2. What is Cisco EFM/EFF?

The Edge & Fog Processing Module provides customers with fully automated software to manage an extensible distributed computing model, with the ability to:

  • Capture and transform data, normalizing it to make it usable
  • Apply rules to data in motion
  • Perform distributed micro-processing where needed, from edge to endpoint
  • Securely and reliably deliver data
  • Maintain historian data
  • Visualize data

Cisco EFM is formerly referred to Cisco Edge and Fog Fabric (EFF). EFF product brings together diverse entities----such as devices, services, and applications----into one IoT data system. By representing these entities as one system, EFF makes possible and simplifies various tasks, such as analytics, inter-device communication, distributed computing, and application development.

Cisco EFF is an open architecture platform that enables immediate processing and analysis of distributed data. EFF accommodates a wide variety of distributed/ IoT use cases, from simple to very complex. EFF is an architecture that is modular and open up to 3rd parties. This allows other vendors to create microservices for their own purposes to connect them to this architecture.

8. Why I did not see the dslink of ParStream-Import? or why it failed to start the dslink of ParStream-Import?

You need to install Java JRE/JDK 1.8. You may use the command "sudo apt install openjdk-8-jre-headless" to install JRE/JDK in Ubuntu 16.04 Linux. For the ParStream DSA Link and the Cisco Smart License Agent, it needs Java 8 JRE or JDK.
