EVALUATION OF HIGH-SPEED MULTIMEDIA COMMUNICATION ARCHITECTURE IN ATM NETWORKS

This paper discusses and evaluate a high speed multimedia communications in ATM networks. Communication platforms below AAL layer in ATM networks can provide fairly high speed communication channel for ATM-UNI. On the other hand, the conventional data processing architecture in the workstations can not provide sufficient throughput compared to the throughput of ATM networks at this time. Also, regarding error-free peer-to-peer data communications, conventional transport protocol, e.g. TCP, can not provide small latent communication, when the product of communication bandwidth and propagation delay is large. This paper focuses on protocol architecture, especially on error control policy at SSCS in AAL layer, and on performance evaluation of high speed multimedia communication based on the current data processing architecture.
