I am looking for a way to rate limit how many SOAP transactions per second that a given customer can send us such that any given customer could not overload the system and cause impact to other customers. As an example, say our system can handle 1000 transactions per second and our normal load from all customers is 500 tps. If a given customer has a huge traffic increase they could overload the system and cause issues for other well behaving customers. Would it be possible in the F5 (probably through the use of an iRule) to identify traffic from a specific customer (preferably based on data within the soap payload, but I suspect in reality it would have to be based on source IP) and then track what the current transaction rate is and in some way block connections exceeding the limit? I assume to block it would require just terminating the session, though optimally we would send back a soap error or even http error. Not being an expert in iRules myself I am mostly wondering if the F5 can even implement a rate tracking and limiting capability within TCL that would perform even remotely well. Any suggestions are appreciated. -Eric _______________________________________________________________ Eric Rosenberry Sr. Network Engineer | Chief Bit Plumber Direct +1. 503.943.6763 | Mobile: +1.503.348.3625 | Fax: +1.503.224.1581 iovation 111 SW Fifth Avenue Suite 3200 Portland, OR 97204 www.iovation.com<http://www.iovation.com/> The information contained in this email message may be privileged, confidential and protected from disclosure.
