修正HSDB网络的性能分析

Performance Analysis of Modified HSDB Network

提出了一种修正的高速数据总线（ＨｉｇｈＳｐｅｅｄＤａｔａＢｕｓ，ＨＳＤＢ）令牌传递协议，该协议允许令牌按步长不等于１沿逻辑环路传递，利用排队论理论，分析了修正ＨＳＤＢ协议的性能，并同标准的ＨＳＤＢ协议进行了比较，结果表明该修正协议可减少令牌循环时间。

A modified HSDB (High Speed Data Bus)token passing protocol is proposed,which allows the token to pass around logical ring by step P≠1,and then,based on queueing theory,the performance of the modified HSDB protocol is analysed and compared with that of the standard HSDB protocol. Results showthat the modified protocol can decrease token rotation time.
