摘要
用户的多QoS需求,使得网络服务中的动态资源属性值变化频繁,传统方法难于对这些动态资源进行分配.为解决这一问题,提出了一种处理多QoS需求的动态资源优化算法.算法引入混沌理论,结合优化算法与逼近理想解排序思想,将多个动态资源形成一个链表在这些资源的各个QoS需求间进行选择调度,并在迭代过程中使用并行算法来降低算法陷入局部最优解的可能性.实例验证了该算法求解该问题的可行性和有效性,具有较好的实际应用价值.
Research the multi—QoS requirements of users.This paper puts forward a dynamic resource optimization algorithm based on multi—QoS requirements.Algorithm with chaos theory,combined with optimization algorithm and approximating the ideal solution sort thought.More dynamic resource form a linked list which is selected scheduling among QoS requirements of these resources,and parallel algorithms use iterative process to reduce the algorithm into a local optimum solution.The experiment results show that the improved algorithm is feasible and effective to solve the multi-QoS requirements problem,and has a certain practical value.
