    abstract =  {This document defines a load control event package for the Session Initiation Protocol (SIP). It allows SIP servers to distribute user load control information to other SIP servers in the network. The load control can throttle calls based on their source or destination domain, telephone number prefix or for a specific user. The mechanism helps to prevent signaling overload and complements feedback-based SIP overload control efforts.},
