Location of Transfer Centres on Segments of a Communication Network with Proportional Traffic
研究了在负载较重的局域网中，通过放置桥梁缓解拥堵的问题，并推广到需求线性排列的其他场景中，发现按比例流量模型下缓解拥堵的能力非常有限。
The problem of placing bridges to alleviate congestion in a heavily loaded local-area computer network is briefly described. It is suggested that the generalization to that of placing transfer centres in other situations in which demand is arranged linearly may also be profitable. In order to obtain a better understanding of the problem, this paper concentrates on models in which demand is proportional (that is, the traffic intensity from one user to another is proportional to the product of their activity rates as measured by the traffic each produces). The results are rather surprising, it being demonstrated that the extent to which congestion can be relieved is severely limited.
