[Rpm] Test procedures for TCP stacks ?

[Toerless Eckert]

Are thre any well defined (RFC or the like) test procedures for the "quality"
of TCP stacks ? I am especially thinking about measuring how good the
TCP stack behaves in the face of various path problems. Latency, loss,
reorder,.

How big a difference between goodput and throughput would one be able to
see anyhow between worst... best TCP stacks ?

Thanks!
