Alternative Transport Architecture for Core ATM Networks

Abstract

In order to remain competitive in an increasingly aggressive market-place, it is essential that network operators deliver cost-effective, resilient bulk transport. This will enable the unit costs of circuit delivery in the core network to be reduced, while assuring high-level quality of service. In particular, the growth in advanced data services which exploit ATM technology will place significant demands on the core transmission layer of telecommunications networks. This paper investigates alternative transport architectures for core ATM networks.
