Abstract

Stream path selection within convergent networks. Any one or more different types of metrics (e.g., related to any one or more of delay, packet error rate (PER), wink bit rate stability, etc.) may be attached to/associated with various messages communicated within such a convergent network. Such messages may correspond to talker advertise (TA) messaging session relay protocol data units (MSRPDUs). Messages may be advertised over each of or a number of different respective communication links. A communication path, which may be composed of a number of different respective communication links between respective communication devices such that each respective communication link has an associated at least one metric, maybe characterized using one or more of the metrics associated with those different respective communication links. A metric of the communication path may be associated with a relatively lowest metric of the different respective communication links composing the communication path.

Dependent claims

An apparatus, comprising:

an input/output port for receiving a plurality of messages, such that each of the plurality of messages associated with a respective at least one of a plurality of attributes and each of the plurality of messages also associated with a respective at least one of a plurality of communication links corresponding to a plurality of communication paths between the apparatus and at least one additional apparatus;
and
a processing module for processing the plurality of messages in accordance with selecting at least one of the plurality of communication pathways for supporting communications between the apparatus and the at least one additional apparatus;
and wherein:
via the input/output port, the apparatus transmitting at least one additional message to the at least one additional apparatus indicating the apparatus being ready to receive subsequent communications from the at least one additional apparatus;
and
the apparatus and the at least one additional apparatus implemented within a convergent network also including a plurality of bridges such that each of the plurality of communication links respectively connecting a respective two of a plurality of communication devices of the apparatus, the at least one additional apparatus, and the plurality of bridges.
