为了解决因传输控制协议(TCP)链接重置而产生的冗余数据,提出在端到端数据传输路径的最后一跳监控TCP重置消息,在继续转发这个消息前丢弃该TCP链接的缓存数据,从而减少冗余数据的转发.为验证该机制的有效性,基于NS-2构建了一个长期演进网络模型,并进行了广泛的实验验证.仿真结果表明,该机制能减少系统丢包率,提高网络吞吐率并降低分组的平均时延和平均抖动,从而提高网络的性能.
In order to solve the redundant data generated due to the TCP reset, it is proposed to monitor the TCP reset message at the last hop of the end-to-end data transmission path and discard the cached data of the TCP link before forwarding the message , So as to reduce the redundant data forwarding.In order to verify the effectiveness of this mechanism, a long-term evolution network model is built based on NS-2 and a wide range of experimental verification is carried out.The simulation results show that this mechanism can reduce the system packet loss rate, Improve network throughput and reduce the average packet delay and average jitter, thereby improving network performance.
