摘　　要：针对以太网网络性能随网络负载变化的特性,提出一种基于以太网负载的改进CSMA协议。该协议根据终端冲突数目,相应调整1-坚持CSMA协议、非坚持CSMA协议和P-坚持CSMA协议,从而在轻载时降低延时,在重载时减少冲突,使得网络系统处于稳定状态。实验结果表明,负载对网络吞吐量与网络延时有重大影响,改进CSMA协议能达到网络吞吐量最优化的目的,并且提高网络实时性,大大提升了网络通信效率。In order to improve the performance of Ethernet network with the change of network load,an improved CSMA protocol based on Ethernet load is proposed.According to the number of node conflict,the protocol adjusts the three types of agreements:1-Persisitent CSMA,P-Persistent CSMA,and Nonpersistent CSMA.Experimental results show that the load has a significant impact on the network throughput and network latency.The CSMA protocol can be improved to optimize the network throughput,the improved CSMA protocol can optimize network throughput,improve network real-time performance and greatly improve the efficiency of network communication.

关 键 词：以太网 CSMA协议 网络负载 吞吐量
