Abstract:
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 closing at least one media channel to a second media endpoint device wherein the request contains a descriptor of the first media endpoint device. The method then updates one or more slot states and link states in response to the request and records the current state of each slot for supporting the media channel. The method also records the most recently received descriptor of the media endpoint device as a most recent descriptor for the slot supporting the media channel. The method executes one or more link objects in response to the request for controlling the at least one media channel.
