Since the traditional transmission control system has the problems of low network throughput and high round?trip delay,a data rapid capture based transmission control system of heterogeneous network link is proposed and designed. According to the characteristics of heterogeneous network,the overall diagram of the module is designed,and the initialization module, task scheduling module,data transmission module,image transmission module are analyzed. On the basis of traditional conges?tion avoidance algorithm,the fast recovery algorithm is optimized to design the transmission control system. The experimental re?sults show that the system design can improve the average network throughput greatly,reduce the round?trip delay value,and improve the network transmission control performance.%针对传统传输控制系统存在网络吞吐量低、往返时延高等问题,提出并设计了基于数据快速活肤的异构网络链路传输控制系统.根据异构网络特点设计模块总体框图,并对初始化模块、任务调度模块、数据传输模块、图像传输模块展开分析.在传统拥塞避免算法基础上,对快速恢复算法进行优化,由此完成传输控制系统的设计.实验结果证明,该系统设计可大大提高网络平均吞吐量,降低往返时延值,改善了网络传输控制性能.
