基于服务质量的动态资源分配算法
Dynamic resource allocation algorithm based on service quality
摘要
Abstract
In the process of network virtualization, the most current physical resource allocation algorithms mainly consider resource utilization and network revenue, but ignore the service quality causing unfairness between different users. To solve above problem, a dynamic resource allocation algorithm based on quality of service is proposed. In the case of discontinuous idle time frequency resources, only when the life cycle of the virtual network request is long enough and the redistribution impact factor is met, the algorithm reallocates physical resources for small virtual network requests with higher priority. In the case of continuous idle time frequency resources, considering the impact of priority, time tolerance and network revenue factors, the proposed algorithm allocates the adaptable physical resources for virtual network requests. Compared with the traditional dynamic resource allocation algorithm based on lifetime priority and greedy dynamic allocation algorithm, the proposed algorithm with better physical resources efficiently not only guarantees the quality of the virtual network requested, but also reduces the running time.关键词
