摘要
Abstract
In view of the technology development trend and the application need of data distribution of Tracking and Data Relay Satellite System(TDRSS),the problems and performance bottleneck of existing server-based high-speed data distribution mode are analyzed.The network processor-based data distribu-tion mode is given,whose advantages over server-based mode are studied.Then the hardware and software proposals of network processor-based high-speed data distribution equipment are proposed,while three high-speed data distribution methods are put forward.By comparing the three methods,the best one is cho-sen.Network CPU-based data distribution mode is 200% greater than the server-based distribution mode by performance testing comparison.关键词
