Abstract: In one embodiment, the information required for routing between IP Telephony Administration Domains (ITADs) is gathered automatically by a location server which operates in the listen-only mode and which is peered with a TRIP inter-domain protocol. The peered location server uses the TRIP protocol to discover routing information thereby allowing for the automatic updating of route data for both internal and external telephony routes. In one embodiment, the peered router maintains an up-to-date picture of the service provider's routing and time stamps the colleted data, thereby allowing for the collection and utilization of historical TRIP performance information. Based on such a historical analysis, the service provider can keep track of, for example, its most reliable peers, peering routes, unstable routes, unavailable routes, etc.

Abstract: Systems and methods are provided for computing the demand placed on a packet-switched network by streaming media carried by such packet-switched network. More particularly, systems and methods are provided that use the signaling messages associated with streaming media communications over a packet-switched network, such as H.225.0 signaling messages associated with Voice over IP (VoIP) telephony communications, to compute the demand placed on the packet-switched network by the streaming media communications. In certain embodiments, the computed demands are used to construct a traffic matrix for the packet-switched network, which may be used by a streaming communication service provider to monitor its quality of service and/or perform capacity planning, as examples.
