HSDB网络稳定性的研究

高速数据总线（ＨｉｇｈＳｐｅｅｄＤａｔａＢｕｓ，ＨＳＤＢ）是新一代航空电子系统的数据总路线，ＨＳＤＢ网络实际上是基于线性令牌总线的一个专用计算机局域网，在网络上负载较重且时间非苛刻的消息到达是一般过程的条件十分别讨论了网络的局域和全域稳定性，并导出了保证整个网络稳定的令牌握有定时器最小值，同时给出了如何根据应用去调整得到的理论值。

STUDY OF STABILITY FOR HSDB NETWORK

The high speed data bus (HSDB) is a new generation data bus of avionic bus. In fact, the HSDB network is a dedicated computer local network. The local and global stability are discussed under the condition of heavy load and a generic process for timer-noncritical message respectively. In addition. the minimum value of token holding timer for stable network is derived, and how to tune the obtained theoretical value according to d.plications is shown eventually.
