Bridging core and edge networks for residential subscribers

We survey various internetworking scenarios between core and edge networks for residential users. The focus is not on individual protocols. Instead we try to show how these protocols can work together. We divide an end-to-end network into core networks and edge networks. We then consider two options for core networks: ATM-based and IP/MPLS-based. For each core/edge architecture, we further consider various access architectures for residential users. We show how these access architectures can be integrated with the two core architectures. Based on the specific requirements of core and edge networks, we discuss the benefits and problems of each solution.
