ATM network architecture for supporting the connectionless service

Abstract

An ATM (asynchronous transfer mode) network architecture for supporting connectionless service aimed at inter-LAN communication and high-performance distributed applications is presented. Two service scenarios, the related reference configuration, and a possible internetwork scenario for supporting the connectionless mode terminal are presented. A discussion is also presented of addressing and routing schemes and the two types of cell transport methods proposed for interconnection between the customer premises network and the connectionless service function (CLSF) located within the ATM network. The appropriate solutions for the cell transport methods are shown. As an application of the ATM connectionless service, a description is given of the gateway architecture supporting the inter-LAN communication via the CLSF.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
