我们研究通信过程模型集合的动态特性，其特征是单个参数 xi 代表节点的信息负载与其传递该信息的能力之间的关系。迄今为止报告的向拥塞的关键转变仅发生在 xi=1 时。该案例针对不同的网络拓扑进行了很好的分析。我们重点关注接近临界点时序参数、敏感性和时间相关性的属性。对于 xi1，向拥塞的过渡是不连续的，并且会出现拥塞核。
We study the dynamical properties of a collection of models for communication processes, characterized by a single parameter xi representing the relation between information load of the nodes and its ability to deliver this information. The critical transition to congestion reported so far occurs only for xi=1. This case is well analyzed for different network topologies. We focus on the properties of the order parameter, the susceptibility, and the time correlations when approaching the critical point. For xi1, the transition to congestion is discontinuous and congestion nuclei arise.
