METHOD AND SYSTEM FOR DISPATCHING RECEIVED SESSIONS BETWEEN A PLURATLITY OF INSTANCES OF AN APPLICATION USING THE SAME IP PORT

摘要

A logical module, referred as Load Balancer Module (LBM), is disclosed which listens to one of certain common predefined port number. These well-known ports for receiving communication video conference signaling and control protocols is thereafter load balanced and multi-plexed to a number of instances of protocol stack applications. By balancing the multi-media data stream across a multitude of application instances multiple multi-media data streams may be serviced and processed by a single internet protocol host processor. A multipoint control unit (MCU) may therefore process multiple input data streams containing multi-media video conferencing information.

1. A method of load balancing a plurality of instances of processes supporting one or more multi-media conferences over an internet protocol network comprising:
instantiating a load balancing module on a host processing unit; instantiating one or more instances of a protocol stack on the host processing unit in response to a request from the load balancing module; receiving at the host processing unit inbound multi-media data packets from a plurality of endpoints participating in one or more multimedia conferences; selecting, by the load balancing module, an instance from the one or more instances of the protocol stack to process each received inbound multi-media data packet; associating, by the load balancing module, the endpoint with the selected instance for the duration of a multi-media conference; transferring the received inbound multi-media data packets toward the associated instance independently of the load balancing module; receiving inbound multi-media data packets not previously associated with an instance of the protocol stack by the load balancing module; instantiating, at the request of the load balancing module, a new instance of the protocol stack; and passing the checked inbound multi-media data packet to the instantiated new instance.
