Hello

What are sources of latency in process of sending/receiving tcp/udp packets in linux 2.6 ?

I want to know a latency sources in "ping-pong" latency tests.

There are some rather good papers of ethernet latency, but they cover only latency sources in the wire and switch (and rather cursory, only for specific switch).

What steps of processing does follow a packet?

Papers with deep latency analysis of usual ping (icmp) will be useful too.

I rely on community :)
