2.Discussion of the results

Summary :

  1. VPP performs better than OVS.
  2. Prox performs better than T-Rex
  3. Bi-Directional Prox is more inconsistent (throughput) than unidirectional
  4. Trex results are not consistent.
  5. Increasing hops, even with single node, affects the performance.  Better summary for varying topologies
  6. Prox has some limitations - mainly w.r.t core assignments - which affects the performance.
3.Limitation of L3

Image Added

Any of these two (red and green) paths even possible without manually adding routes/flows?

Using IP-address is easy with iperf/netperf. Whereas, a Tgen (Prox/Trex), with DPDK-interfaces, it gets difficult.

Not sure if our IPAM configurations are correct - Working on finding the right configuration (if any).

How Userspace CNI handles IPAM configuration is not clear - with VPP, we didn't see any routes getting added.

Reach out to Luc/Yuri - to check if they have achieved this with Prox. Maybe, Prox-L3swap mode can respond to ARPs.
