摘　　要：分析了多因性多址协议及并应用于Web传输,在QoS异步预测算法提出和研究基础上,提出一种多因性多址协议QoS异步预测算法,对Web通信信道优化建模,建模包括拥塞控制,差错控制设计,实现对网络传输中帧率和比特率的自适应控制。仿真实验表明,新算法能克服传统算法丢包率随着输出总码率的升高而升高,导致丢包率不符合QoS标准的问题,算法能有效应对大规模Web资源传输的需求,比传统方法具有优越性和普适性,收敛性好,自适应调整速度快,在大存储量网络资源传输通信中具有可观的应用前景。The multiple factor performance of multi-address protocol was analyzed and applied it in the Web communica-tion. An improved QoS asynchronous prediction algorithm was proposed based on the multi-factor and multi address proto-col. The QoS prediction algorithm was researched, Web communication channel modeling was constructed, which including congestion control, error control design. The frame rate and bit rate adaptive control was realized as result. Simulation re-sults show that the new algorithm can overcome the weakness of traditional method that the packet loss rate increases with the total output rate, and the algorithm can meet the demand of large scale Web resource communication. It has perfor-mance such as superiority and universality with good convergence. Research result has good application prospect in a stor-age cyber source transmission communication.
