Abstract

In view of the low performance of traditional TCP protocol in transmitting large files in the current network environment, this paper studied and optimized the slow start algorithm of TCP transport protocol. According to the problems of standard slow-start algorithm and the performance characteristics of high-speed network and large file transmission, this paper proposed an improved slow-start algorithm with network state awareness. The improved algorithm mainly optimized the growth strategy of TCP congestion window, which monitored RTT of TCP packets in real-time during the transmission process, and updated the congestion window with different window growth methods according to the changes of RTT. It deployed the improved algorithm in the Linux network module and tested it in the simulated network environment and the actual network. Experimental results show that the improved algorithm can keep the sending window at a higher level, and the actual data transmission rate and throughput have been significantly improved.
