摘　　要：随着大数据的应用及智能化的发展,传统网络已无法满足需求不断升级及网络流量高速增加的需求.针对这一情况提出了一种新型网络架构即软件定义网络,突破网络和应用程序之间的不兼容,对整个网络资源进行合理配置和集中管理,达到网络数据的灵活可控,最终实现网络管理和配置的实时性及自动化,从而解决现存网络系统的网络阻塞以及不可扩展性.基于软件定义网络的多路径路由选择算法,通过定义权重变量,对控制器进行多方面均衡考虑,最终利用对多个目标的优化评估实现路由选择.通过仿真实验可知,该算法可以提升网络负载均衡性,避免链路拥塞发生,提升用户体验,保障网络性能.With the application of big data and the development of intelligence,the traditional network has been stretched when facing the continuous upgrade of application requirements and the rapid increase of network traffic.In view of this situation,a new type of network architecture,namely software-defined network,is proposed to break through the incompatibility between the network and applications,to reasonably configure and centrally manage the entire network resources,and then to achieve flexible and controllable network data,and finally realize the network Real-time management and configuration and automation to solve network congestion and non-scalability of existing network systems.A multi-path routing algorithm is based on software-defined networks.By defining weight variables,the multiple aspects of equilibrium is considered about controller.Finally,it optimizes the evaluation of multiple targets to achieve routing.It is known through experimental simulations that the algorithm can improve network load balance,avoid link congestion,and improve user experience to ensure network performance.
