摘要
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(M AC)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 ethernet and controlnet are discussed. A detailed discussion of the medium access control (MAC) is provided.The ethernet bus with carrier sense multiple access with collision detection(CSMA/CD) and controlnet with token-passing bus are compared. The transmission time and data coding efficiency are compared by emulation.
