Release notes, January 3, 2017

Netrounds software version: 2.18.0

New features

Speedtest with WebSockets

The Speedtest application can now alternatively be run using WebSockets instead of Flash. Speedtest with WebSockets has the following properties:

  • Flash is replaced with standard javascript web APIs such as WebSockets and WebWorkers.
  • The test traffic is sent over WebSockets, which allows for IPv6 and HTTP proxy support.
  • Additional TCP metrics are collected by sampling the Linux kernel "tcp_info" struct on the Test Agent. These metrics are presented on a new tab TCP info on the test page.
  • The test page is hosted at a different address than the Flash-based Speedtest: http://app.netrounds.com/<account_name>/speedtest-websocket.
  • The test page is hosted over HTTP instead of HTTPS.

Speedtest with WebSockets is currently a beta version with the following limitations:

  • The test duration for upload and download tests is limited to 10 s. The number of TCP sessions during these tests is limited to 8.
  • There might be a big difference in performance between different browsers on the same system.

Note: Speedtest with WebSockets requires that you update Test Agents to software version 2.18.0.1. Otherwise the Test Agents will not be listed among the servers on the Speedtest page.

User interface enhancements

  • The new Test Agent nomenclature has been adopted throughout the user interface:
    • Probe/Agent has been replaced by Test Agent, which covers both and corresponds to the older term Genalyzer.
    • Probe and Agent are distinguished as Test Agent Appliance and Test Agent Lite respectively where needed.
  • Drop-down boxes with up to seven items have been replaced by toggle buttons, making selection quicker.
  • The ability to filter by tag in the Monitoring section of the Dashboard has been restored.

Transparency test for new Ethernet protocols

A newly introduced test checks transparency for the following Ethernet control protocols:

  • LACP, Link Aggregation Control Protocol
  • EAPoL, Extensible Authorization Protocol over LAN
  • MVRP, Expected outcome for Multiple VLAN Registration Protocol

For each protocol to be tested, five frames are generated and sent, and a pass/fail result is obtained.

New Path MTU test

A new test type Path MTU discovery has been added in the Transparency category. Furthermore, the RFC 6349 TCP throughput test has been updated to use the new Path MTU discovery algorithm in its first step.

Improvements

Sign-up page

The Netrounds sign-up page has been modified to achieve a smoother transition from the netrounds.com website.

Bug fixes

IPTV crashes

The IPTV tool crashed if the same multicast group was used for several IPTV channels.

DVB-C

Unhelpful error message ("Unknown error") when trying to run multiple concurrent DVB-C monitorings with channels on different frequencies (muxes). This is not supported since the hardware can only tune to one frequency at a time. – An adequate error message is now shown when attempting the above.
