软件定义网络通过将控制平面与数据平面分离而提出了一种新的范例。控制平面的主要职责部署在称为SDN控制器的集中式组件中。因此，基于SDN的网络变得依赖于单个功能实体（尽管它可能具有多个实例），以便完成其路由和策略规则。SDN控制器容易由于众所周知的称为软件老化的现象而退化。据我们所知，这项工作是第一次评估软件老化对当前SDN控制器实施的影响。我们表明，这种现象在未来的软件体系结构设计和实现中不能被忽视。
Software-Defined Networking proposes a new paradigm by separating the control plane from the data plane. The control plane's main responsibility is deployed in a centralized component called SDN controller. Therefore, the SDN based network becomes dependent on a single functional entity (although it may have multiple instances) in order to accomplish its routing and policy rules. The SDN controller is vulnerable to degradation due to a well-known phenomenon called Software Aging. To the best of our knowledge, this work is the first that assesses the impacts of software aging on current implementation of SDN controllers. We show that such a phenomenon must not be neglected in future software architecture designs and implementations.
