Re: [vpp-dev] #vpp #vpp-dev
Hi Nikhil, If your client and server are attached to the same vpp instance, data/segments never make it into vpp. Instead, during the connect, after vpp detects that the two endpoints are both attached locally it sets up the session buffers (fifos) in a piece of shared memory that’s mapped by both peers (we call these cut-through sessions). At that point the exchange of data is nothing more than memcpy to/from the fifos. If you want to see packet pass through vpp, you’ll have to attach the client and the server to separate vpp instances that are connected by a network.

[Edited Message Follows] Hi All, I am testing the VCL socket programs i.e. vcl_test_client and vcl_test_server on ubuntu VM. Just wanted to check that the TCP packets are sent by client to server are they coming from TCP graph nodes? i have not observed this on VPPCTL. Also when i saw the trace on VPPCTL, i haven not seen TCP packets. Can anyone please shed some light on this? Thanks in advance.

I run this, I see time is reset.
Start traffic.
“clear run”.
Wait several seconds.
“show run”.
But I did not understand how to do "Add up clocks/pkt/node for data-plane nodes
to form total clocks/pkt" Could you please explain more clearly where and how
to add it.

Add up clocks/pkt/node for data-plane nodes to form total clocks/pkt. Results
valid only for the prevailing vector rate, CPU type, CPU clock frequency, etc..
Vpp nodes run dramatically more efficiently as the vector size increases, up to
the point where rx ring drops occur.

You can use 'show run max' to display the per-node stats (including vector size) *when the node took the most cycles to complete*. This will not necessarily gives you the max vector size, but it should be close. There seem to also be stats around handoff like 'trace frame-queue' 'show frame-queue trace', 'show frame-queue histogram' but I am not familiar with those.

Look around 11:30:11 you have unit test failures.
