目前广泛使用的局网的柘朴如构是总线(单总线)型,在该结构中防止冲突的主要方法之一是 CSMA/CD 或CSMA/CA,但该法不能用在总线访问频度很高之处。本文提出一种双总线的局网结构,在此结构中,除原来的总线外,还用一条总线,把访问概率最高的共享设备和处理机连在一起。理论证明了双总线局网可以减少冲突、提高设备的利用率。
One of the main methods of preventing collisions in this architecture is CSMA / CD or CSMA / CA. However, this method can not be used in the case of high bus access frequency Department. This paper presents a dual-bus network structure, in this structure, in addition to the original bus, but also with a bus, the access probability of the highest shared devices and processors connected together. The theory proves that the double bus station network can reduce the conflict and improve the utilization of the equipment.
