Changelog

v2.2.1

  • Better support for 4-pipe Tofino
    • Increase meter entries & register entries to 512 to be able to use ports with PID > 255
  • Bug in analyze mode that returned an error when no streams / stream settings were provided
  • Preliminary import/export function for settings
  • Fix bug that prevents that ARP replies are always generated in ANALYZE mode

v2.2.0

  • Added VxLAN support
  • Added infobox in UI to get further information on features
  • Random Ethernet src addresses are now always unicast
  • Detection mechanism that clears local storage if stored streams do not have all required properties
    • This may be the case if an update introduces new properties, but the old stored values in local storage dont have them
  • Refactor Configuration GUI code
  • Switch to utoipa + swagger-ui for REST-API docs
  • Add config.json file that can be used to specify the traffic generation (front panel) ports
  • Add ARP Reply option in UI. If enabled, the switch answers all ARP requests that it receives on that port.

Refactor REST-API endpoint /api/trafficgen

  • Endpoint /api/trafficgen refactored to better reflect encapsulation methods
  • Streamsettings are now grouped according to protocol (see /api/docs for examples)
    • Ethernet related configuration (src & dst mac) are now under ethernet
    • VLAN & QinQ related configuration are now under vlan
    • IP related configuration are now under ip
    • Fields (vlan, mpls_stack, vxlan) are only required if corresponding encapsulation is active
  • number_of_lse in stream description is now only required if MPLS encapsulation is used

v2.1.2

  • Added RTT visualization
  • Cleaner monitoring routine in controller
  • Add "port clearance" before P4TG starts. May be needed if other systems configure the switch (e.g., SONiC). See #6

v2.1.1

  • UI bug-fix total TX/RX frame tpes
  • Remove "non-unicast" from frame chart

v2.1.0

  • Added MPLS support with up to 15 MPLS labels
  • Integrated configuration GUI webserver in controller
    • The configuration GUI is now also served at http://ip-of-controller:controller-port
  • Moved REST-API to /api endpoint of the controller. It is now served at http://ip-of-controller:controller-port/api
  • Added visualization on the GUI for traffic rates, packet loss & out of order, frame statistics

v2.0.0

Have you considered Rewriting It In Rust?

v.2.0.0 includes several improvements over v1.0.0.

  • Added VLAN & QinQ encapsulation
  • Added Ethernet type counter (VLAN, QinQ, IPv4, IPv6, Unknown)
  • Switched to data plane mean IAT & MAE (mean absolute error) measurement
    • Sample mode (as in v.1.0.0) available via Controller environment variable (SAMPLE=1)
    • Data plane mode (SAMPLE=0) is more accurate and the default
  • Configuration GUI re-design & enhancements / bug fixes
  • Rewrite of the control plane in Rust
  • REST-API endpoint documentation
