随着信息社会的发展,网络中的信息流量开始急速增长,光网络不仅需要大容量和长距离的传输,还需要动态和灵活的管控,传统自动交换光网络架构的通信模式很难满足这一需求。同时,海量数据的存储访问,需要扩展性极强的分布式存储架构来实现。针对面向数据中心之间互联的多域光网络,提出了一种基于SDN的跨域光网络虚拟化服务的资源权衡策略。实验证明,该方法可以对网络资源进行高效合理的映射分配,提高业务接受比、降低网络阻塞率,满足用户的需求。
With the development of information society,the information flow in the network began to grow rapidly,optical network requires not only large capacity and long distance transmission,but also the need for dynamic and flexible controls,the traditional automatic switching optical network architecture is very difficult to meet it. At the same time,storage access to massive amounts of data is a very high requirement for the scalability of the distributed storage architecture. A resource balancing strategy based on SDN for the inter-domain optical network virtualization service was proposed. Simulation results indicate that network resources can be allocated effectively,service acceptance ratio is improved,and network blocking probability is reduced.
