storage over IP (was Re: [PLEASE-TESTME] Zerocopy networking patch,
I haven't tracked the IP storage group too closely, but was at the San Diego IETF where there were some interesting debates about this issue.
There is a write-up at http://ips.pdl.cs.cmu.edu/mail/msg02598.html
Now I'm not sure if I agree with some of the assumptions. And I share your concern about using multiple tcp streams.
Thoughts?
cheers,
karthik

show that both use TCP/IP. TCP/IP has variable length headers (or am i on crack?), which totally complicates the receive path.TCP has variable length headers. It also prevents you re-ordering commands in the stream which would be beneficial. I've not checked if the draft uses multiple TCP streams but then you have scaling questions.
