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 (VoIP) and Service over Internet Protocol (SoIP) 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.
