iRule to calculate client bandwidth usage

what is different with applying rate class to virtual server without calculation?

maybe i should have posed my question a little different and explain the situation...

 

 

I have clients connecting to a VS to download files and once they have downloaded say 500mb of data then i need to shape the traffic down so for instance shape the traffic down for that perticular client so once they hit a download limit of 500mb then the bandwidth they are allowed is down to say 1mbit/s.

 

 

Thanks.

just wondering whether you have seen this one. would it be applicable?

e.g.

 

 

[root@ve1023:Active] config b virtual bar list

 

virtual bar {

 

snat automap

 

pool foo

 

destination 172.28.65.152:http

 

ip protocol tcp

 

rules myrule

 

}

 

[root@ve1023:Active] config b rule myrule list

 

rule myrule {

 

when SERVER_CONNECTED {

 

TCP::collect

 

}

 

 

when SERVER_DATA {

 

set srvAge [IP::stats age]

 

set srvBytes [IP::stats bytes in]

 

if {$srvAge > 10000 } {

 

if {$srvBytes > 3000000 } {

 

rateclass bandHog

 

TCP::release

 

log local0. "Bandwidth Hog: [IP::client_addr] server bytes $srvBytes"

 

return

 

}

 

}

 

TCP::release

 

TCP::collect

 

}

 

}

 

[root@ve1023:Active] config b rate class list

 

rate class bandHog {

 

rate 1Mbps

 

ceiling 1Mbps

 

drop policy tail

 

type sfq

 

}

 

 

[root@ve1023:Active] config tail -f /var/log/ltm

thanks thats a great start for me to go on, will have a re-jig of the rule and see whati come up with :)
