摘要: 为进一步提高实时话音和视频数据业务传输的服务质量,结合多协议波长标签交换网络的基本原理,通过对标签分配策略进行分析,提出一种改进的反馈式轮转调度算法,在优先为高优先级分组进行调度的同时,可以防止低优先级的分组因长期得不到调度而超时被丢弃。实验结果证明,该算法能够合理分配链路带宽,保证良好的时延性能。

Abstract: In order to further improve the QoS over real-time voice and video data transmission, by considering the basic principle of Multi-Protocol Lambda Switching(MPLmS) network and analyzing label distribution strategy, this paper proposes an improved feedback Round Robin(RR) schedule algorithm. It prioritizes the priority of the high-priority packet schedule, and prevents the lower priority group from discarded because of failing to be scheduled in a long time. Experimental results show that the algorithm can distribute the link bandwidth effectively to ensure good performance of time delay.
