  • Patent number: 7620033
    Abstract: Reduction of administrative overhead in maintaining network information, rapid convergence on an optimal routing path through the data network, and utilization of only required network resources are realized by a novel method for establishing a call path between network users. The method is based upon deployment of a network information server that stores network topology information and that is addressable by each end user. In this method, the network information server receives a request to establish a call path. The request identifies at least the calling party. In response to the request, the network information server determines a network traversal between the calling party and a root network wherein the network traversal includes call path information about the sub-networks between the calling party and the root network. The request for establishing a call path can also identify the called party.

  • Publication number: 20090109856
    Abstract: A system and method for reducing switching overhead in a communication network and a web-based server incorporating the system or the method. In one embodiment, the system includes: (1) an optimization engine configured to receive input data describing trunks, switches and traffic demands in at least a portion of the communication network and arrange connections between the trunks and switches such that the traffic demands are satisfied and such that a switch load or cost is reduced and (2) a report generator associated with the optimization engine and configured to produce a report containing a modified configuration having the reduced switch load or cost.
