Abstract:
1. A method for modifying routing using a topological address space map of a system having a plurality of networks connected to a backbone via a plurality of entry points, the method comprising: monitoring, by a network device, the entry points of a plurality of messages arriving from the plurality of networks; correlating the plurality of message entry points with their associated message source address ranges to develop the topological address space map of the system; and using the topological address space map in conjunction with a program code to implement modified routing, wherein said program code includes at least program code that preferences a route table route that is not selected naturally according to a network routing protocol and is not prohibited according to a network configuration parameter, subject to a determination that the route exceeds a signal quantity threshold, wherein said topological address space map includes at least information associating said message source address ranges with their topologically closest backbone connection point.
