这种方案称为基于局部域的重传方案。
We call such a scheme local-scope-based retransmission scheme.
仿真结果表明，与传统方案相比，自适应选择重传方案在高误帧率环境下以较低的误包率、略大的传输时延获得了较高的TCP吞吐量。
Numerical results demonstrate ASR-ARQ can achieve much lower packet error rate with slightly longer delay and higher TCP throughput than the conventional scheme.
同时提出了通过限制实时性业务重传时间来改进D - EDCA机制的初步方案，并对该方案进行了仿真与分析。
The revised D-EDCA is proposed by restricting the retransmitted times of the real-time traffics. Furthermore the performance of the revised D-EDCA schemes is analyzed briefly.
同时，该方案还考虑在网络拥塞时对重传请求进行缓冲等待处理，这样就不会因为向上级缓冲路由器发送该请求而加重拥塞的程度，甚至造成该重传请求的最终丢失。
The retransmission request will be waiting in the buffer when congestion occurs in the upstream path, so it can avoid worsening the congestion and even losing the request.
