Necessary capacities of computer networks` core components

Abstract

The creation and development of computer networks and data centers involves considerable expenses. Minimizing these expenses is important. In this paper, the backbone subnet and server set of wide area computer networks are examined to determine the necessary capacities of their channels, routers and servers, considering the linear dependence of their costs on their capacity. The proposed in this aim queuing network model is an extension of the respective model for channels proposed by L. Kleinrock based on Jackson’s theorem.
