ABSTRACT:
A method and apparatus for improving SIP server performance is disclosed. The apparatus comprises an enqueuer for determining whether a request packet entering into the server is a new request or a retransmitted request and its retransmission times and for enqueuing the request packet into different queues based on results of the determining step and a dequeuer for dequeuing the packet in the queues for processing based on a scheduling policy. The apparatus may further include a policy controller for communicating with the server, enqueuer, dequeuer, queues and user, to dynamically and automatically set, or set based on the user's instructions, the scheduling policy, number of different queues, each queue's capacity, scheduling, etc. based on the network and/or server load and/or based on different server applications.
