[AusNOG] Why not Symmetric ingress and egress?

[Dmitri Kalintsev]

Chris,

Thanks for that. The idea that an application could potentially work around
system-wide settings is intriguing, but the description of setsockopt() does
not seem to indicate the possibility to set send and/or receive windows
size, which are the parameters in question:

I would gladly stand corrected, as this is a very interesting and relevant
question. The reason why it is, is because the topic of performance of TCP
applications over "long fat pipe" type of transmission infrastructure keeps
on coming up from customers I land up dealing with (indirectly) in a pretty
persistent fashion.
