High-speed multimedia backbone LAN architecture based on ATM technology

Abstract

A new high-speed multimedia backbone LAN (MBLAN) architecture that efficiently accommodates existing terminals and offers connectivity with public networks in the introduction stage of broadband ISDN (B-ISDN) is presented. A logical 156-Mb/s ring with the standard synchronous optical network (SONET) format is a basic element to realize the proposed high-speed backbone LAN. Several rings are multiplexed into a 622-Mb/s or 2.4-Gb/s physical transmission line. The slotted ring access method is utilized for each logical ring in order to provide a multimedia communication facility. The slot size and format are based on the asynchronous transfer mode standard and offer easy connectivity with B-ISDN. Independent clocking using the SONET stuffing mechanism is also introduced to solve the jitter accumulation problem.<>
