A Simulation Approach to Daily Bandwidth Allocation in a 250 Nodes Virtual Private Network

Abstract

In order to make better use of available network resources, there is a need for planning the bandwidth allocation to communication demands. In this study a bandwidth allocation problem was formulated with three major constraints. A dynamic mathematical model was developed and a Genetic Algorithm method was adopted for an optimization solution. The GA algorithm was implemented with Java programming language. The model was simulated for ten thousand (10,000) generations. Two hundred and fifty (250) nodes were simulated differently under varying bandwidths values of 64Kbps, 128Kbps, 256Kbps, 512Kbps, 1Mbps, 2Mbps, 4Mbps, and 8Mbps for a period of twenty four (24) hours. Simulation results show that utilization factors can be as high as ninety nine percent if optimization conditions are scrupulously observed.
