摘要
主要讨论了以太网和控制网的网络工作机理,对以太网总线和控制网总线的介质访问控制(MAC)的子层协议,采用带碰撞检测的载波侦听多点访问方式(CSMA/CD)和控制网的令牌传送总线作了详尽的比较,并用仿真方式比较了它们的传输时间和数据编码效率.
In this paper, the mechanisms of Ethemet and ControlNet are discussed. A detailed discussion of the medium access control (MAC) is provided. The Ethemet bus of carrier sense multiple access with collision detection(CSMA/CD) and ControlNet with token-passing bus are compared. Their time transmission and data ceding efficiency have been emulated.
