摘　　要：分组失序是由并行交换衍生出来的一种网络现象,分组失序会降低TCP传输性能。为此,我们建立了一个简单的并行交换节点仿真模型,通过仿真得到了基于并行交换系统的单个TCP连接分组失序统计分布,为研究分组失序对TCP性能的影响提供了比较可信的基础。Packet reordering is a common event, which may affect and even depress TCP performance. Previous researches have declared that packet reordering is caused from parallel process switching system. But the distribution of the packet reordering scale has not been proposed yet, we build a simple simulation module of parallel packet switching system with OPNET. From this module some meaningful simulation results and conclusions are acquired. All these results are more reliable and reasonable.
