一种基于多链路的通信子系统的设计与实现

A design and realization of communicaion sub system based on multi-link

当前分布式计算机系统中一般采用基于单链路的通信子系统。单物理链路的带宽往往成为分布式系统的性能瓶颈;同时单链路失效可能导致系统不可用。基于多链路的通信子系统可解决这种带宽和可用性问题。本文设计实现了一个多链路通信子系统。测试表明,该系统同时提高了系统的通信性能和可用性。可普遍应用在分布式体系结构的计算机系统设计中。

Distributed computer system currently uses communication subsystem based on single-link. One link's bandwidth is generally the performance bottleneck of distributed system.; further more one link's crash may lead to the system's invalidation. Communication subsystem based on multi-link resolves the bandwidth and availability problems of communication subsystem. In this paper a communicati on subsystem based on multi-link is realized. The test result indicate s that this system Improves both system performance and system availability. This method can be used In the design of computer system with distributed system architecture.
