摘要 分组调度是实现计算机网络QoS保证的核心问题。该文描述了SFQ+分组调度算法,在SFQ算法的基础上引入了DWCS的动态窗函数约束机制,并与传统的SFQ和DWCS算法作了比较,给出了算法的性能评价,对算法的扩展进行了展望。 Packet schedule is the key mechanism for Internet QoS guarantee. This paper describes a new packet schedule algorithm --SFQ^＋, which introduces the dynamic window-constrained scheme into SFQ. This paper shows the performance analysis of SFQ^＋ comparing with SFQ and DWCS, and finally offers the future research on the algorithm.
