On the surface, I don't see a problem with it, but I wonder why you believe it is needed. Changing the value of rexmttresh is probably not a good idea, and I would definitely prefer not to expose it as a user tunable knob. -- Jonathan On Sat, Nov 17, 2001 at 06:51:02PM -0600, Alfred Perlstein

I recommend you all look at The Click Modular router http://www.pdos.lcs.mit.edu/click/ which is a step in the right direction. Of course given the current architecture it may be very hard to adapt it to this kind of model. I led/worked on a project at Wind River Systems to do a multi-instance

Hello, 1. Is there any sysctl variable to control the number of duplicate acks after which the sending TCP gets into a fast retransmit mode? 2. If I have a switch that does not support any port aggregation, and it is connected to a BSD machine with 2 ethernet NICs that have identical MAC, will
