Optimization Modeling and Analysis for Bandwidth Allocation in Communication Networks with Penalty Cost

摘要

In this paper, we present an analysis on optimization and risk management in Communication Networks (CNs). The model is proposed for offline traffic engineering optimization, which takes a centralized view of bandwidth allocation, performance control, and risk control of network profit shortfall. First, we introduce a linear penalty cost in the CN optimization model and derive the optimal bandwidth capacity with the penalty cost. Then, we use the mean- variance approach to analyze the profit shortfall risk in CNs. Finally, numerical results are shown to reveal the impact of the linear penalty cost on the CNs performance.
