Three techniques are proposed for reducing the time required for protocol processing: protocol data unit management using page management, assembly and disassembly of data packet header and contents in hardware, and rescheduling of protocol processing. These techniques were shown to be feasible by applying them to the TCP/IP over a fiber-distributed data interface network. The maximum communication throughput was 91.6 Mbps; the total throughput for 64 sessions was 89.6 Mbps, only 2% less than the maximum. These techniques will enable the development of more effcient video-on -demand systems.
