软件定义网络（SDN）是一种控制平面与数据平面分离、集中实现的新型网络体系结构。控制平面一般有两种模型：单控制器和分布式控制器。单个SDN控制器面临一些问题，例如可扩展性和单点故障。为了解决这些问题，分布式模型被引入。经典的分层模型被认为是分布式SDN控制器的主要类型之一。在本文中，我们介绍了一个有效的分层SDN模型，以减少负载的根控制器相比，经典的分层模型。
Software defined network (SDN) is a new architecture for network in which the control plane is separated from data plane and implemented centrally. There are two general models for the control plane, single and distributed controller. A single SDN controller faces with some problems such as scalability and single point of failure. Distributed model is introduced to solve these problems. The classical hierarchical model is known as one of the main kinds of distributed SDN controllers. In this paper, we introduce an efficient hierarchical SDN model to reduce the load of the root controllers in comparison with classical hierarchical model.
