Research of the retransmission policy based on compound parameters in SCTP-CMT

摘要

In order to solve the rbuf blocking in concurrent multipath transfer, firstly, this paper analyzes the reason for receiving buffer blocking and the disadvantages of traditional retransmission policies. And then, it proposes an improved retransmission policy - RTX-CR (retransmission-congestion window and RTT), which can reduce rbuf blocking. The simulation indicates that the retransmission policy can reduce receive buffer blocking and achieve better transmission performance.
