网络的传输容量是指网络在不引起拥塞的情况下所能处理的最大流量流入速率。在这里，我们研究如何通过将资源分配给各个节点，同时保持可用资源的总量来增强这个数量。提出了一种实用有效的基于节点连通性局部知识的节点能力再分配方案。我们表明，我们的方案提高了传输容量的异构结构的网络高达两个数量级。
A network’s transmission capacity is the maximal rate of traffic inflow that the network can handle without causing congestion. Here we study how to enhance this quantity by allocating resource to individual nodes while preserving the total amount of the resource available. We propose a practical and effective scheme which redistributes node capability based on the local knowledge of node connectivity. We show that our scheme enhances the transmission capacity of networks with heterogeneous structures by up to two orders of magnitude.
