Dive deep into your results, test USP over MQTT, lw4o6 support and more in CDRouter 11.6

September 12, 2019 • 2 min read

We’ve released CDRouter 11.6, with some transformative changes to how you can analyze packet captures in your test results, the addition of lw4o6 to our growing list of supported IPv6 transition mechanisms, and support for MQTT transport when testing USP/TR-369. You can read the full release notes to find out more!


Testing over lw4o6 IPv6 transition architecture

There are many specialized transition mechanisms that allow the co-existence of IPv4 and IPv6 networks, including 6rd, DS-lite, MAP-T, MAP-E, and more. In our latest release we’ve added support for lw4o6, an extension to DS-lite that moves NAPT functionality into the CPE.

All of these co-existence technologies are complex, and our team does its best to make sure we’re on top of the latest protocols for helping IPv4 and IPv6 networks work together.


MQTT support for the User Services Platform (TR-369)

The Broadband Forum has released version 1.1 of USP, the revolutionary protocol that builds on TR-069 for the next generation of the connected home. As part of its flexibility, USP supports multiple “Message Transfer Protocols”, or MTPs, to send messages in different scenarios for different use cases. Version 1.1 adds MQTT to this list, a message broker protocol that has become one of the more widely used technologies in the IoT.

CDRouter’s fully automated, scriptable USP Controller now has support for USP messages sent over MQTT.


Improved packet capture analysis with CS TraceFrame 1.2

If you haven’t yet seen CloudShark by QA Cafe, it was born out of CDRouter and transformed into the world’s first web-based, collaborative packet capture analysis tool built for teams. Things came full circle when improvements to CloudShark’s packet viewer were turned into its own devkit, called CS TraceFrame.

CDRouter 11.6 has upgraded our packet viewer to use CS TraceFrame version 1.2, improving the speed and performance of the packet viewer to make reviewing test logs and narrowing in on issues faster than ever before.
