Administering a communication network
View Patent ↗Methods and apparatus are provided for administering a communication network. In one embodiment, a first interface screen depicts nodes within a network. The nodes include a pair of media aggregation managers providing multiplexing/demultiplexing of media traffic associated with multiple application sessions between a pair of communities onto a preallocated reservation protocol session between the media aggregation managers. The media aggregation managers are visually distinguishable from other nodes. A second interface screen depicts potential paths through the network. Each potential path is capable of transferring media packets between the media aggregation managers. Via the second user interface screen, a network administrator is capable of initiating (1) path-level configuration of routers that are part of a selected potential path to cause the routers to route media packets exchanged between the pair of communities over the selected path, and (2) establishment of the preallocated reservation protocol session between the media aggregation managers.
