Performance Evaluation Analysis about Ethernet and DeviceNet

摘要：

The mechanisms of medium access control (MAC) layer about Ethernet and DeviceNet are discussed in detail in this paper. The Ethernet bus with carrier sense multiple access with collision detection(CSMA/CD) and DeviceNet with token-passing bus are compared. Its transmission time and data coding efficiency are emulated in MATLAB. The emulated result shows the transmission time of Ethernet is lower than DeviceNet but it almost is constant in little data capacity. The compare data capacity with data coding time about Ethernet and DeviceNet shows the coding efficiency of Ethernet is lower than DeviceNet in little data capacity but in big data capacity it is more.
