Version 11.0

First full release of the Web UI. Contains all the major impairments, filters, statistical graphs, traffic generators, Traffic Capture and Replay. See “7.x features not included in this WebUI release” below for a short list of notable omissions.

Enhancements

  • Completely overhauled user interface, now accessed from a standard web browser

  • Greatly enhanced editing functions (group select, copy / paste, zoom, undo previous actions)

  • Dashboard shows layout of network cards along with their status (including port reservation status)

  • Two different themes (light theme and dark theme) to suit users' individual preferences

  • Integrated help system

  • HTTPS support

  • Remote Control API additions: StopAsync and Status endpoints (for maps with large delays), also the ability to retrieve statistics for individual impairments or whole maps

7.x features not included in this WebUI release:

  • Wireshark

  • Timeline automation

  • Virtual Routing

  • SNMP traps

  • PTP synchronisation

Version 7.0

Enhancements

  • Bandwidth Throttle now supports up to 20MB input buffer

  • In multi-user mode, port reservation can now be performed via the REST API

  • Updated Start / End Point statistics, added individual / global port statistics reset, added individual / global port link reset (via right-click)

  • MPEG H.264 impairment re-implemented. Added H.265 dynamic payload and H.265 support

  • Added new Markov Packet Drop mode

  • Accumulate and Burst impairment how supports delay time of up to 1 second

Defect Fixes

  • Start Point packet duplication did not work correctly in some scenarios with real world traffic

  • Fixed Packet Corruptor enable / disable via REST API

  • Traffic Replay with large packets could cause the system to reboot

  • Packet Drop impairment did not return correct settings via REST API until traffic passed through it

  • Port reservation did not handle non-contiguous licensed ports correctly

  • Maximum time for Accumulate and Burst was lower than expected when Jumbo mode enabled

  • RTP Statistics TAP performance improved
