Abstract
Mechanisms for burst traffic smoothing for Session Initiation Protocol (SIP) processing elements are provided. A dispatch queue management engine determines whether a received packet is a TCP or UDP packet. If the packet is a TCP packet, the packet is automatically added to the dispatch queue. If the packet is a UDP packet, a value for a drop function ƒ is generated and a random or pseudo-random number r is generated. If r has a predetermined relationship to ƒ, then the UDP packet is added to the dispatch queue, otherwise the UDP packet is discarded. The value for ƒ is based on the current dispatch queue load, the network quality, the retransmission rate, and the allowable drop rate. Thus, the determination as to whether to drop UDP packets or not is configurable by an administrator and also adaptable to the current network and dispatch queue conditions.
