摘要
在保证提高网络系统可靠度的基础上,降低网络链路成本是计算机网络可靠度优化计算中的重要目标之一.为此,在计算机网络可靠度优化计算时,考虑了计算机网络链路介质成本、网络可靠度数学模型以及模型求解的算法等因素.阐述了遗传算法及其执行过程,并将遗传算法应用于降低网络链路总成本,提高网络可靠度的优化计算之中.仿真结果表明,遗传算法解决了以往传统算法难以解决的网络可靠度优化计算问题,不但加快了计算速度,而且更有效地提高了优化计算效果,具有较好的操作性.
To decrease network link cost is one of the most important paimsrs tor computer network reliability optimization design. In order to make the network cost minimum, the network link medium cost, mathematics mode of reliability and resolve algorithm must be considered when it is designed. In the paper, we present a genetic algorithm Used in optimization calculation for minimizing total link-cost and increasing the reliability of the network. Executive procedures of the algorithm are described. The simulation results show that genetic algorithm provides a method to resolves the network reliability optimization problem which normal approach can not resolve. By using the maneuverable algorithm, optimization process is accelerated, efficiency is increased.
