摘要：

软件定义网络和网络功能虚拟化能够有效解决大型网络难以管控、资源调度困难等问题。随着大规模卫星网络广泛应用，用户数量激增，对服务性能要求逐渐增加，这给网络管控和资源调度带来极大的负担，将软件定义网络的架构模型以及网络功能虚拟化等技术应用在大规模卫星互联网，可以有效解决目前存在的一些问题。提出基于SDN/NFV的新型卫星互联网架构，不同的卫星域可负责不同的功能，星间和域间可利用SDN和NVF进行有效协作，高效地利用网络资源，同时对其服务功能资源分配技术进行研究，优化VNF部署；提出基于资源感知的模拟退火算法，仿真结果表明此算法可以有效地降低服务功能链（SFC）数据流在传输时的端到端时延和带宽消耗，可以为用户提供更好的服务。

Abstract:

Software-defined networks and network function virtualization can effectively solve the problems of difficult management and control of large-scale networks and diffi culties in resource scheduling.Applying the software-defi ned network architecture model and network function virtualization technologies to the large-scale satellite internet can eff ectively solve some problems.This paper proposed a new SDN/NFV-based new satellite internet architecture, different satellite domains could be responsibled for different functions, inter-satellite and inter-domain could used SDN and NVF for eff ective collaboration, effi cient used of network resources, research and optimization of its service function resource allocation technology after VNF deployment, a simulated annealing algorithm based on resource awareness was proposed.Simulation results showed that this algorithm could effectively reduced the end-to-end delay and bandwidth consumption of SFC data fl ow during transmission, and could provided users with better services.
