混合网络架构下业务服务控制技术研究

Services Control Technology in Hybrid Architecture

软件定义网络(SDN)是一种新兴的网络架构,采用控制与数据分离的思想。由于SDN网络的诸多优点,出现了SDN与传统IP网络融合的状态。SDN业务与非SDN业务在业务特点、建立方式、业务需求等诸多方面存在差异。因此,重点就如何在一个共同的网络中满足SDN与非SDN业务的网络服务需求的问题进行研究。首先提出对SDN和非SDN业务的定义和业务保障策略,其次对两类业务的传输机制进行设计,最后通过仿真试验,验证采用的动态分配技术的改进效果。

Software Defined Networking （SDN）, as new network architecture, adopts the idea of separating control from data. For its many advantages, occurs the situation in integrating SDN and traditional IP networks. There exist many differences of between SDN services and non-SDN services in service characteristics, establishment mode, service requirements, and so on. SDN business and non- SDN business are different in many aspects, such as business characteristics, establishment methods, business needs and so on. Therefore, the focus is on how to meet the needs of SDN and non-SDN services in a common network. Firstly, the definition and business guarantee strategy for SDN and non-SDN services are proposed. Then the transmission mechanisms for the two types of services designed. Finally the simulation test indicates the improved effect of this dynamic distribution technology.
