在“虫孔”寻径网络中，阻塞对网络性能有决定性影响．研究阻塞随网络参数及负荷的变化规律，对于确定影响网络性能的关键因素、优化系统设计，都有重要意义．本文定义了一个刻划网络阻塞程度的新指标——阻塞比，利用阻塞比研究了８×８，１０×１０，１６×１６，２０×２０和３２×３２等五种规模的二维网格中，网络阻塞随网络负荷的变化，证明“虫孔”寻径网络的阻塞状态存在三个区域：零区、线性区和饱和区，进入饱和区是突变式的，存在一个导致网络饱和的负荷临界值
In the “worm hole” routing network, blocking has a decisive impact on network performance. Studying the variation of congestion with network parameters and load is of great significance for determining the key factors affecting network performance and optimizing the system design. In this paper, we define a new indicator of the degree of network congestion - blocking ratio, the use of blocking ratio of 8 × 8,10 × 10,16 × 16,20 × 20 and 32 × 32 other five-dimensional two-dimensional grid , The network congestion changes with the load of the network. It is proved that there are three regions in the “wormhole” routing network: the zero area, the linear area and the saturation area. In the saturated area, there is a mutation and there is a load that causes the network to be saturated Threshold
