TCP-BASED ADAPTIVE NETWORK CONTROL TRANSMISSION METHOD AND SYSTEM

摘要

A TCP-based adaptive network control transmission method. A network coding layer is added between a transmission layer and a network layer of each of a transmitting end and a receiving end in a conventional TCP/IP architecture of a network, network coding packet headers with specific variables are added to coding packets and ACK response packets in the network coding layers, the variables are transmitted and updated between the receiving end and the transmitting end by utilizing the coding packets and the ACK response packets, and a redundancy coefficient R is adjusted in the network coding layer of the transmitting end by utilizing the variables. By the method for dynamically adjusting the redundancy coefficient, the resistance of a protocol to burst loss can be enhanced, the redundancy coefficient R is kept at an optimal value as much as possible in a network environment with a constantly changing loss rate, and the throughput and link utilization rate of the network are increased.
