高速分组交换网络中调度器的设计

为了满足迅猛发展的网络业务对网络服务质量提出的更高要求，使用高速分组网络交换机中的队列调度器可以有效地提供高质量的网络服务。通过采用分级式队列调度和四种队列调度算法有效地实现了队列调度器的设计。并且深入地比较和分析了队列调度器中多种队列调度算法的优缺点，尤其是对DRR调度算法进行了优化和改进。最后。对所设计的电路进行了仿真验证和电路综合，结果表明该调度器可以满足网络对服务质量的更高要求，并且能够应用到高速分组交换网络的调度器设计中。

Design of Scheduler in High Speed Packet Switching Networks

The rapid development of intemet business puts forward higher request for the quality of service in the network, the queue scheduler of the high speed packet switching network can effectively provide the higher quality of service in the network. It uses hierar- chical scheduling and four queue scheduling algorithms to realize the design of queue scheduler. What＇ s more,it compares and analyses deeply advantages and disadvamages among kinds of scheduling algorithms in the queue scheduler, especially, improves and optimizes DRR scheduling algorithm. At last, It completes the simulation verification and circuit synthesis for the circuit design, and the results show that the scheduler can satisfy the higher quality of service of the network and can be applied to scheduler design of high speed packet switching network.
