一种新的介质访问控制方法

A New Kind of Medium Access Control Method

针对以太网流行的星形拓扑布线结构 ,提出了一种新的共享介质无冲突访问控制方法。这种方法在低负荷时等同于CSMA/CD ,高负荷时效率比环网效率更高。特点是要发送数据则立即发送 ,由集线器避免冲突。

Gives a new kind of collision avoidance medium access control method for the present popular star topology architecture of Ethernet. The performance of this method is equal to CSMA/CD in light load and is better than ring net when the load is heavy. The character of this method is to send data immediately when the data is ready and to avoid the collision with the hub.
