Designing communication subsystems for high-speed networks

Is shown that system structure and implementation of a communication subsystem are vital elements in high-throughput protocol implementation. A well-structured and carefully implemented subsystem can exploit high-speed transmission links and preserve their speed up to the application. The issues of memory management and organization are presented as examples. Support for data movement and processing overlap, and intelligent DMA, two alternatives for the communication subsystem to achieve higher performance and scale to higher-speed links, are discussed.<
