摘　　要：随着网络技术(如5G/6G,边缘计算)的不断更新换代,网络功能虚拟化(network functions virtualization, NFV)和软件定义网络(Software Defined Network, SDN)成为下一代网络体系结构的主要使能技术,而高效安全资源分配问题始终是新型体系结构所面临的巨大挑战.文中融合NFV和SDN的优势,在用户请求和物理资源之间引入虚拟资源层,从而一定程度上实现物理资源安全.另外,提出了基于SDN-NFV的通用化资源映射和复用机制.主要框架结构包含3个模块:资源初始化模块、资源监控模块、资源动态分配与调整模块.其中,资源动态分配与调整模块是本文核心模块,主要通过建立资源映射模型、资源复用模型和资源调整模型来优化全网资源利用率.仿真结果表明,该机制通过在物理资源和虚拟资源之间建立动态映射关系,实现资源的高效复用,进而提高资源的利用率.With the continuous upgrading of network technologies such as 5G/6G and edge computing,network function virtualization(NFV)and software defined network(SDN)are the main enabling technologies in the next generation network architecture.However,efficient and secure resource allocation is always a huge challenge for new architectures.This paper integrates the advantages of NFV and SDN,and introduces a virtual resource layer between user requests and physical resource,thus to realized the physical resource security in a certain extent.In addition,an universal resource mapping and multiplexing mechanism is proposed based on SDN-NFV.The main framework consists of three modules which are the resource initialization module,resource monitoring module,resource dynamic allocation and adjustment module.Among which the resource dynamic allocation and adjustment module is the core that it optimizes the resource utilization of the whole network by establishing resource mapping model,resource multiplexing model and resource adjustment model.The simulation results show that the mechanism can realize efficient multiplexing of resource and improve the utilization of resource by establishing dynamic mapping relationship between physical resource and virtual resource.
