摘要
为了解决虚拟网络请求阻塞率较高和底层物理网络资源利用率较低的问题,提出一种基于节点链路同时映射的多类型服务资源编排的算法.在映射首节点时,考虑物理网络节点属性;在映射节点链路元组时,综合考虑物理网络节点属性和链路属性;在映射链路时,考虑网络链路属性,从而在包含多类型服务资源的底层物理网络中找到虚拟网络请求的映射策略.仿真结果显示,所提算法可以降低虚拟网络请求的阻塞率,提高物理网络多种类型资源的利用效率.
Abstract
To tackle the issues of a high blocking rate of virtual requests and underutilization of physical network re-sources,a heuristic algorithm for orchestrating multi-type service resources was proposed by simultaneously mapping nodes and links.The physical network node attributes were considered when mapping the first node,the physical net-work node attributes and link attributes were comprehensively considered when mapping node-link tuples,and the net-work link attributes were considered when mapping links,so as to find the mapping policy for virtual network requests in the underlying physical network containing multiple types of service resources.Simulation results show that the pro-posed algorithm can reduce the blocking rate of virtual network requests and improve the utilization efficiency of mul-tiple types of resources in the physical network.
