连通性在网络拥塞和去拥塞中的作用
Role of connectivity in congestion and decongestion in networks
摘要：
研究了具有规则节点和枢纽的二维通信网络中的网络流量动力学。如果网络经历繁重的消息业务，则由于节点的有限容量而发生拥塞。我们讨论的策略，以操纵枢纽容量和枢纽连接，以缓解拥塞，并定义了介数中心性（CBC），网络流量的直接测量，这是有用的，用于确定最有可能导致拥塞的枢纽系数。在高CBC的枢纽增加替代性连接可以非常有效地缓解拥堵。
英文摘要：
We study network traffic dynamics in a two dimensional communication network with regular nodes and hubs. If the network experiences heavy message traffic, congestion occurs due to finite capacity of the nodes. We discuss strategies to manipulate hub capacity and hub connections to relieve congestion and define a coefficient of betweenness centrality (CBC), a direct measure of network traffic, which is useful for identifying hubs which are most likely to cause congestion. The addition of assortative connections to hubs of high CBC relieves congestion very efficiently.
