still needing help !

i m very sorry to say that i hardly have got any useful stuff regarding controlling tcp rate, rather packeteer information was good (TCP Rate Control - by Shrikrishna Karandikar).

what i want to do is everytime i want to establish a connection with any server(say X-server ) on the basis that X should send me data at agreed upon rate, the rate should not increase beyond that value.

can i implement it? if yes where can i find information?

 

Ok,next was

for classifying packet by making use of marking

what if i m using u32 classifier instead of fw.

is there utility with u32 to mark packets.

also,

what i think is that, classifiers will come into the picture after the connection establishment, so how could they differentiate 2 different type applications for same service?

10x in advance

ganesh.
