摘要 针对传统的输入排队交换结构的数据包切分策略带宽利用率低、灵活性差等缺点,提出一种自适应包切分策略。新策略利用集中式调度的同步特性,在调度过程中通过输入端的队列状态来确定切分单元的大小,并动态调整算法匹配时间,有效地减少了填充字节和系统所需加速比。仿真分析表明,与现有的包切分策略相比,采用自适应策略的交换结构更能适应实际网络环境,且具有良好的时延性能。 Focusing on the problem of low bandwidth utilization and poor flexibility of traditional packet segmentation scheme for input queued switches,an adaptive segmentation scheme was proposed.Because of the synchronous properties of centralized scheduling,the new scheme adjusts the length of segmentation unit and the matching time during the scheduling by using the status of input ports,which can reduce the padding data and the speed up that the switch needs.Finally,the simulations demonstrate that the proposed scheme exhibits good delay performance under different traffic models and is well applicable to real network.
