Rate limit to n connections / each ip

Hi,

 

 

Im very new to Tcl/iRules, so maybe my question is very basic. I would need (original begining eh?) limiting the number of connections from each client to n.

 

 

So...

 

 

src ip x max concurrent http connections 200

 

src ip y max concurrent http connections 200

 

src ip z max concurrent http connections 200

 

 

i tought making a hash $table{$src_ip}=$number_of_connections (sorry, the most similar language to Tcl i know is perl...)

 

 

is there any better way of doing this? memory and cpu usage might be an issue as i have no less than 200 clients...(i have a ltm 6400 series)...

 

 

one more! ... if the client goes beyond n (number of connections) redirects to a pool...well, thats not that hard i guess..

 

 

comments are very welcome : )

forgot to mention, based on delta time...so its n connections / t seconds...

 

 

so , no more than 200 connections on a 20 seconds gap...

 

 

 

 

Hi Eric,
