In order to cope with the actual requirements of business applications and improving utilization of network bandwidth to a certain extent.This paper provided a method to optimize the TCP links and the data forwarding buffer on the basis of the general real-time data forwarding system(RTDFS).The method was mainly based on the network link status and the characteristics of real-time data arrived at forwarding system,utilized the relevant theories of queuing theory to build the corresponding mathematical model,and made use of main parameters which affected TCP transfer throughput,then figured out the best data forwarding buffer size and the number of parallel threads in communication server.The results of actual system implementation show:when the nominal bandwidth is 2M,the round-trip delay between real-time data recording and real-time data forwarding end is about 2ms,the round-trip delay between real-time data forwarding and control center is about 154ms,the bandwidth utilization can be above 90% when buffer is infinite and the number of multi-thread is 4,which verifies the theory computation of mathematic model.
