Communication processing techniques for multimedia systems

Abstract

Key techniques required for communication processing in multimedia systems are (1) high-speed protocol processing of every data packet and (2) simultaneously processing of many sessions. This paper proposes three solutions of high-performance protocol processing: protocol data unit management using page management method, assembling and disassembling of header and contents in hardware, and rescheduling of protocol processing. The feasibility of these techniques have been experimentally verified applying these to the transmission control protocol/internet protocol (TCP/IP) over an fiber-distributed data interface (FDDI) network. As a result, the maximum throughput of 78 Mbps is obtained. The total communication throughput of 64 sessions is 75.6 Mbps, only 3% less than the maximum throughput.<>
