摘要:

对高速线性令牌传递数据总线的性能进行了分析,建立了排队系统模型,并导出了节点消息延时、等待队列长度等网络特性与网络吞吐量之间的关系表达式,着重讨论了AS4074和宝石柱HSDB两种协议的性能差异,得出AS4074在中、低负载情况下性能优于宝石柱HSDB,因而更适合于新一代航空电子综合系统的结论。

Abstract:

This paper studies the performance of a high speed linear token passing data bus. Based on a queuing system model the relationship between network characteristics such as message latency, waiting queue length and network throughput are derived and expressed in functional equations. The performance difference between AS4074 and Pave Pillar HSDB protocol is underlined. The results show that under moderate or low bus load condition, the performance of AS4074 is superior to that of Pave Pillar HSDB, and more suitable to meet the needs of new generation avionics systems.

Key words: performance analysis, linear token passing bus, network protocol, avionics
