Call and connection control on multiaccess ATM customer network

Abstract

ATM technology-based B-ISDN is widely accepted as the next generation high speed communication system. An ATM customer network can be built as a star, bus, or ring topology. However, the main focus of the ATM access network has been the star topology where multiple terminals within the customer network are concentrated on an ATM switch. The demands of residential or small business subscribers have resulted in the need to build an ATM customer network gradually and economically, which can introduce the emerging new multimedia services. A shared medium-based multiaccess technology cannot only allow switches to be smaller but also improve the switch port granularity. It is even possible to connect multiple terminals without an initial need for an expensive ATM switch. In this paper, by considering a multiaccess customer network architecture, we present call and connection control schemes that will play a key role in the feasibility of the multiaccess ATM customer network.
