Abstract:
1. A system for routing of real time communications of packet data over networks, comprising: at least one session border controller connected to at least one ingress network and egress network and operable to associate an ingress call peer for a call being processed, said session border controller being operable to match said ingress call peer to a policy so as to identify an egress call peer for said call, wherein said ingress call peer is a logical grouping for calls associated with the incoming of a call and wherein said egress call peer is a logical grouping for calls associated with the outgoing of a call, wherein matching said ingress call peer to said policy is based on an Internet protocol (IP) subnet and wherein said policy specifies call admission control parameters for said ingress network and determines said egress call peer for transmitting said ingress call to said egress network; a signaling switch connected to said at least one session border controller; a management system connected to said at least one session border controller to record performance data of said at least one session border controller; a database accessible by said at least one session border controller to define a policy for groups of calls, wherein said policy specifies call admission control parameters for said ingress network and determines an egress call peer for transmitting the ingress call to said egress network; said session border controller providing selective media routing, said selective media routing including application of a media routing policy to provision media routing per at least one of call peer and call peer group and realm, said session controller specifying one of intra-call peer routing for routing calls within a call peer, intra-call peer group routing for routing calls within a call peer group, intra-realm routing for routing calls within a realm, inter-call peer routing for routing calls between call peers, inter-call peer group routing for routing calls between call peer groups, and inter-realm routing for routing calls between realms.
