MPTCP中一种减缓缓存阻塞的重传策略

Retransmission Policy to Reduce Receive Buffer Blocking for Multipath TCP

MPTCP中子流间的性能差异、受限的缓存区将导致接收端缓存区阻塞,影响MPTCP整体性能。综合考虑子流的延迟、丢包率、拥塞控制窗口和慢启动门限,提出一种新的重传策略RTX-DLCS。仿真证明该策略能有效减缓缓存区阻塞,提高MPTCP吞吐量。

In multipalh TCP, the difference of subflows and the limited receive buffer lead to receiving buffer blocking. It decreases the global throughput of MPTCP. In this paper, a new retransmissiun policy called RTX-DLCS is given based on lhe delay, loss rate, CWND and SSTHRESH. A demonstrate using simulation is provided showing that it can ,＇educe receive buffer blocking effectively and improve the MFFCP＇s global throughput.
