Very high bandwith packet based interface and performance problems

2001-02-20 Thread Nye Liu
I am working on a very high speed packet based interface but we are having severe problems related to bandwidth vs cpu horsepower. enclosed is a part of a summary. PLEASE cc responses directly to [EMAIL PROTECTED] Thanks!!! -- "Who would be stupid enough to quote a fictitious character?"
