基于抗毁性和最小费用的网络优化设计方法

Design Method of Network Optimization Based on Survivability and Minimum Cost

针对通信网网络优化设计提出了一种在网络抗毁性指标和网络最小费用之间进行均衡、折衷的优化设计方法。分析了通信网络的特点和设计要素,在此基础上提出了将通信网络进行模型化的方法,根据模型化后的图求出最小费用的连通网络结构,在尽量减少费用的前提下进行抗毁设计的修改。通信网络优化设计的最终设计目标是具有一定抗毁性指标且费用最少的网络拓扑结构。

Aiming at optimization design of communication network, this paper presents a balanceable and trade-off method of optimization design in network survivability specifications and network minimum cost. Based on analysis on characteristics and design elements,it proposes a modularization method for communication network and then obtains the connectivity network structure with minimum cost based on the chart from modularization. Finally, the survivability design modification is performed for reducing cost as possible. The final design goal of communication network optimization is to obtain a network topology structure with some survivability specifications and minimum cost.
