【摘要】：软件定义网络(SDN)和网络功能虚拟化(NFV)促进了网络的创新,NFV实现了虚拟网络功能(VNF)的逻辑集中部署。针对v EPC(virtualized Evolved Packed Core)网络中VNF的池组化部署问题,该文提出一种支持节点分割的VNF部署模型,该模型基于虚拟请求业务流量的感知,利用节点分割算法动态调整VNF与底层网络资源切片的映射关系,实现VNF的跨域组池。与传统的多功能链联合映射算法相比,该方法能够实现节点资源细粒度化管理和统筹调度,优化网络视图,减少资源碎片。在SNDlib提供的网络拓扑实例下仿真证明,该模型可以降低虚拟网络的资源开销,并提高虚拟网络的请求接收率。
[Abstract]:Software-defined network (SDN) and network function virtualization (NFV) promote the innovation of network. NFV realizes the logical centralized deployment of virtual network function (VNF). In order to solve the problem of pool deployment of VNF in v EPC (virtualized Evolved Packed Core) networks, a new VNF deployment model supporting node segmentation is proposed in this paper. The model is based on the perception of virtual request traffic. The node segmentation algorithm is used to dynamically adjust the mapping relationship between VNF and the underlying network resource slice to realize the cross-domain group pool of VNF. Compared with the traditional multi-function chain joint mapping algorithm, this method can realize the fine-grained management and overall scheduling of node resources, optimize the network view, and reduce the resource fragments. The simulation results of the network topology provided by SNDlib show that the proposed model can reduce the resource overhead of the virtual network and improve the request receiving rate of the virtual network.
