Bandwidth Optimization Algorithm Based on Bandwidth Ratio Adjustment in Generalized Processor Sharing Servers

We consider a bandwidth optimization problem in a Generalized Processor Sharing servers with multiple class queues to minimize the total bandwidth such that QoS requirements for each class queue are satisfied. In our previous paper [13], since it is difficult to obtain the performance such as the delay distribution mathematically with self-similar input traffic in a GPS server, we obtained an optimized bandwidth vector using a simulation-based optimization technique. However, the previous optimization algorithm requires rather long simulation time to solve the problem by using exterior penalty function methods. We propose a new bandwidth optimization algorithm based on bandwidth ratio adjustment without complex calculations. In numerical results, the required time to find the optimal bandwidth allocation in GPS servers is greatly reduced.
