CENTRALIZED SYSTEM FOR ROUTING SIGNALS OVER AN INTERNET PROTOCOL NETWORK

摘要

A centralized system for routing signals over an Internet protocol network is provided. The system computes routing tables for routers in the network and distributes the tables to individual routers. In another aspect of the invention, a virtual signaling network is provided. The virtual signaling network preferably provides fault information and distributes instructions concerning the routers to the centralized system.
