METHOD AND APPARATUS FOR DISTRIBUTED COMPOSITIONAL CONTROL OF END-TO-END MEDIA IN IP NETWORKS

摘要

A method and an apparatus for performing a distributed control of end-to-end media on packet networks such as Voice over Internet Protocol and Service over Internet Protocol networks are disclosed. The method first receives a request from a first media endpoint device for opening at least one media channel to a second media endpoint device wherein said request contains a descriptor of said first media endpoint device. The method then updates one or more slot states and link states in response to said request and records the current state of each slot for supporting said media channel. The method also records the most recently received descriptor of said media endpoint device as a most recent descriptor for said slot supporting said media channel. The method executes one or more link objects in response to said request for controlling said at least one media channel.

1. A method for providing a control of at least one media channel in a communication network, the method comprising:
receiving, by a processor, a request from a first media endpoint device for closing the at least one media channel to a second media endpoint device wherein the request contains a descriptor of the first media endpoint device; updating, by the processor, a state of a slot and a state of a link in response to the request, wherein the slot comprises an object that corresponds to a potential tunnel endpoint, wherein the link comprises an object that controls the slot; recording, by the processor, a current state of the slot for supporting the at least one media channel; recording, by the processor, the descriptor of the first media endpoint device as a most recent descriptor for the slot supporting the at least one media channel; and executing, by the processor, the object of the link in response to the request for closing the at least one media channel.
