In order to improve the network performance of computer and avoid the occurrence of network congestion better, this paper analyzed the problems faced by the integration of real-time streaming transport and network and their solutions in the perspective of the characteristics of real-time streaming transport. As to the congestion control of streaming media, TFRC algorithm was analyzed emphatically. Based on TFRC, network congestion was improved, monitored and predicted with parameter of real-time cache length; sending rate was corrected based on cache length when the network was saturate, in order to avoid congestion in time and improve fairness; at last, the test comparison proceeded by network simulation platform NS2. The result indicated that, the improved TFRC was fairer; meanwhile, it showed more friendliness to TCP.
