探讨业务量的相关性对排队系统性能究竟会带来什么样的影响，对于高速网络中流量控制机制和资源分配算法具有非常重要的意义。
The impact of traffic dependence on queueing performance is of great significance to traffic control mechanism and resource allocation algorithm in high-speed networks.
在此基础上，建立了用于在视频源数据和FEC 数据之间分配网络带宽资源的优化算法。
On this basis, an optimal algorithm is proposed to allocate the bandwidth resource between the source video data and the FEC data.
仿真实验结果表明，随着分配带宽的减少，LCT算法能够有效地降低多播树的高度和网络资源使用量，并保持较低的多播树延时半径增幅。
The simulation results show that LCT could reduce both hops and network resource usage of the tree effectively, and keep a little increase in delay radius while the allocated bandwidth decreases.
