主 题:dynamic load balancing weighted random sip application server
摘 要:A new load balancing algorithm named dynamic weighed random (DWR) algorithm for the session initiation protocol (SIP) application server cluster is proposed. It uses weighted hashing random algorithm that supports dialog in the SIP protocol to distribute messages. The weight of each server is dynamic adaptive with feedback mechanism. DWR insures that the cluster is balanced, and it performs better than the limited resource vector (LRV) algorithm and minimum sessions first (MSF) algorithm.
