Abstract

The proliferation of edge computing brings new challenges due to the complexity of decentralized edge networks. Software-defined networking (SDN) takes advantage of pro-grammability and flexibility in handling complicated networks. However, it remains a problem of designing a both trusted and scalable SDN control plane, which is the core component of the SDN architecture for edge computing. In this paper, we propose Curb, a novel group-based SDN control plane that seamlessly integrates blockchain and BFT consensus to ensure byzantine fault tolerance, verifiability, traceability, and scalability within one framework. Curb supports trusted flow rule updates and adaptive controller reassignment. Importantly, we leverage a group-based control plane to realize a scalable network where the message complexity of each round is upper bounded by O(N), where N is the number of controllers, to reduce overheads caused by blockchain consensus. Finally, we conduct extensive simulations on the classical Internet2 network to validate our design.

边缘计算的可信和可扩展软件定义网络控制平面

由于分散的边缘网络的复杂性，边缘计算的扩散带来了新的挑战。软件定义网络(SDN)在处理复杂网络时具有可编程性和灵活性。然而，设计一个可信和可扩展的SDN控制平面仍然是一个问题，它是边缘计算SDN体系结构的核心组件。在本文中，我们提出了一种新的基于组的SDN控制平面Curb，它无缝地集成了区块链和BFT共识，以确保在一个框架内的拜占庭容错性、可验证性、可追溯性和可扩展性。遏制支持可信流规则更新和自适应控制器重新分配。重要的是，我们利用基于组的控制平面来实现一个可扩展的网络，其中每轮的消息复杂性上限为O(N)，其中N是控制器的数量，以减少区块链共识造成的开销。最后，我们在经典的internet - 2网络上进行了大量的仿真来验证我们的设计。
