[LARTC] how to determine tcp rate classifying packet info

2003-01-21 Thread ganesh palwe
hello everybody
need help
how should i control the tcp rate, is it possible?
also,
suppose i have 2 database tables :
1) one for online accounting 
2) one for online sales updating
now both of these transactions which will update my SQL server databse will be on the same port number 
how can i classify these packets so that i can give high bandwidth  highest prio to type 2 packets.
10x in advance.

It's possiblewww.lartc.orgwww.docum.org also, suppose i have 2 database tables : 1) one for online accounting  2) one for online sales updating now both of these transactions which will update my SQL server databse will be on the same port number how can i classify these packets so that i can give high bandwidth  highest prio to type 2 packets.What if you the iptables helper that can match packet with a string in it? 
I think the select is unique so you can see the difference. Once you can recognise the packets, you can mark them with iptables. That mark can be used to put the packets in differenct classes so you can configure different rates for the packets.But this will suck if you select statement is too big for one packet.Stef-- 

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 - byShrikrishna 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 tomark 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?
