1Development Update

Work in Progress:

  1. Qemu.
  2. Extracting NIC details from the deployed pod. It is straightforward for pci-id/nic-names, but get tricky with socketfiles. Socketfiles are different for memif and virtio_user.
  3. Tgen+Deployment and Node-Port configuration: automation.
  4. Results collection from vinperf-pod (on console results) - To decide whether the test is completed or not and collection results in PROX case.
22-weeks Off

No meeting for next 2 weeks. Next meeting  2nd March 2022.

Will be available to run tests.

3Kubernetes Dataplane Benchmarking - PROX  and T-REX
  • Prox:
    • VPP – Unidirectional & Bidirectional – 5 topologies
    • OVS – Unidirectional & Bidirectional – 5 topologies
  • Trex:
    • VPP – 3 topologies.
      • net_memif and dummy isn’t supported.
    • OVS –
      • Current: virtio_user0
      • Error: virtio_user not supported.
  • TODO
    • Poor performances in some scenarios*
      • Start writing the explanations- Whys?
      • Highlight issues with Traffic Generators* (Multi-core with prox)
    • Run TRex with BSwLV
    • PROX-OVS with multi-cores should work.
    • Increase test-duration to pickup transients (64)
    • Run: Bi-Di + Prox + VPP + 64Bytes (with Luc)
    • Need to come-up with ‘golden-configuration’ – What is right configuration that will give best-performance (CNI technology – vswitches).
      • separate core for each PMD
      • More cores to VPP (topology 4 and 5) – Already the max (8 cores)… so, no use..
      • To Check:
        • More cores for trex (in Pod defn. file, add resources) – Daniele to test.
        • More cores for prox is not working***
        • Increase queues (Not sure if it is possible). Memif (vpp) and vhostuser(ovs) – "Sridhar to check"
        • Swap node – configuration? (Check with Luc).
