软件定义网络(SDN)中经常发生网络更新，例如策略和路由更改。更新应始终如一地执行，以防止临时中断，并且应尽可能少地占用开销。可伸缩性日益成为SDN的基本要求。在本文中，我们提出使用时间触发的网络更新来实现一致更新。我们提出的解决方案比现有的更新方法需要更低的开销，而不会影响更新过程中的一致性。我们证明，与以前提供的更新相比，精确的时间可以在SDN中实现更高的可扩展性一致更新。此外，它还为SDN程序员提供了对一致性和可伸缩性之间权衡的细粒度控制。
Network updates such as policy and routing changes occur frequently in Software Defined Networks (SDN). Updates should be performed consistently, preventing temporary disruptions, and should require as little overhead as possible. Scalability is increasingly becoming an essential requirement in SDN. In this paper we propose to use time-triggered network updates to achieve consistent updates. Our proposed solution requires lower overhead than existing update approaches, without compromising the consistency during the update. We demonstrate that accurate time enables far more scalable consistent updates in SDN than previously available. In addition, it provides the SDN programmer with fine-grained control over the tradeoff between consistency and scalability.
