A Simulation Study of Routing and Control in Communications Networks*
Jos H. Weber · Bell System Technical Journal · 1964
A set of studies has been undertaken to develop guidelines for the design and operation of communications networks with automatic alternate routing. Comparisons are made of engineered costs and overload capability of networks using several alternate routing configurations, and employing a number of different operating and control procedures. The traffic model selected consists of a 34-node network abstracted from the U.S. telephone toll network, with basic load levels obtained from field data. The overload evaluations were made using a simulation program prepared for the IBM 7090 computer.
