中文摘要：
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．
英文摘要：
When transmission control protocol （TCP） connections are reset, the buffered data in the network will still be forward to the destination based on the current TCP mechanism. A new approach is proposed to solve this problem by monitoring the TCP reset message and dropping the buffered data of the TCP connection before forwarding the message in the last hop. To verify the effectiveness, a long term evolution （LTE） network model is implemented in NS-2. Extensive numerical experiment is carried out. Eimulation shows that the proposed mechanism can greatly improve the network performance in terms of packet loss rate, network throughput, as well as average packet delay and jitter.
