摘要

SDN/NFV为运营商实现网络重构和架构演进提供了支撑技术，业务链及其组网技术是NFV的一个重要应用场景，相关的业务链资源分配问题是业界的研究热点。首先对业务链现状进行了梳理，重点分析了已有的资源分配机制和存在的问题，提出了一种业务链资源分配方案，充分考虑了对网络资源的优化利用，实现了VNF实例放置和业务链路径优化选择。实验结果表明，本方案具有更大的系统用户容量和更短的业务路径。

Abstract

SDN/NFV provides supporting technologies on network re-architecture and evolution for network operator.Service chain and related networking technology is becoming a significant use case of NFV

of which resource allocation is one of the key research points.The service chain status in quo was studied.The resource allocation mechanisms and related problems were analyzed.After that

a service function chain resource allocation scheme

which optimizes the usage of the network resource and realizes virtual network function instance deployment and route selection

was proposed.Experiment results show that the proposed method is able to serve more traffic.
