Abstract

System and method for managing networks addressed via common network addresses. The system and method facilitate proper routing and processing of network packets within a network data processing environment. The system and method include and involve a router that has an interface for communicating a network packet. The network packet includes a network address. The interface has a unique interface identifier relative to the router. The router is configured to map the network address and the unique interface identifier to a unique network address and to replace the network address in the network packet with the unique network address. The system and method also include and involve a management system that is coupled to the router. The management system is configured to receive the network packet from the router, to map the unique network address in the network packet to a customer and/or usage identifier, and to process the network packet and data contained therein based on the customer/usage identifier.
