Abstract
Like any other Internet-based service VoIP servers can get overloaded. This overload can result from a denial of service attack, flash crowd scenario or hardware and software problems on the VoIP server itself. To be able to properly react to the overload the VoIP servers will have to monitor the incoming traffic and identify the causes of the overload. Depending on the cause of the overload and the overloaded resource different overload control mechanisms will have to be deployed. Without such mechanisms, VoIP services can fail and can hence not be trusted as replacement to PSTN services. This paper looks into the issues that need to be solved with regard to controlling the load at SIP servers, the different possibilities for controlling the load and some of the still open issues.
