基于争用型以太网的数据帧长研究

在以太网数据传输中,节点在发送数据之后的一定时间内,由于传输的非实时性,存在着遭遇碰撞的可能。节点发送的帧很小且2个冲突节点相距很远,数据产生冲突的可能性会变大,使网络的实际利用率降低。数据帧太大会出现节点等待时间太长或接收端缓冲溢出。以太网数据传输中的最小和最大帧长对网络的利用率有很大影响,传输距离变化使帧长也会产生相应的变化。

Comparison of Contention-Based Ethernet Data Frame Length Study

While the Ethernet is transferring data, after the node sends data within a certain time, there may be possibility of encountering collision since the non-real-time transmission. Frame node sends two conflicting nodes which are so small and far distance between two that enlarge the possibility of conflict of data, and reduce the use ratio of network. Too much data frame will cause node waiting too long or a buffer overflow. The minimum and maximum frame size in Ethemet data transmission has a great influence on the utilization of the network, the change of long distance transmission will make frame length have a corresponding change.
