Integrative traffic control for broadband communication system with multiple channels

本研究旨在提出一种适用于多信道宽带通信系统的综合流量控制架构。研究了在大带宽时延积通信系统中多媒体综合业务和传输控制协议（TCP）的性能。在此基础上，我们提出了两种考虑信道状态的动态差错控制方案。所提出的方案的性能进行了评估的分析方法和计算机模拟。得到了双信道情况下吞吐效率的解析表达式。数值结果表明，与已有格式相比，所提格式是有效的。

This research aims to propose a framework of the integrative traffic control for broadband communication system with multiple channels. We investigated the integrated traffic of multiple media and the performances of TCP (transmission control protocol) in the communication system with large bandwidth-delay product. Based on the preceding study, we proposed two dynamic error control schemes under the consideration of the states of the channels. The performances of the proposed schemes have been evaluated by the analytic method and computer simulation. We obtained the closed-form expression of the throughput efficiency at the case of two channels. Compared with the existing scheme, the effectiveness of the proposed schemes is shown by the numerical results.
