Abstract

Software-defined networking (SDN) is the rising technology in near future to build programmable networks as a way to simplify the evolution of networks. It is a new networking paradigm with the main aim is to decouple forwarding hardware from control decisions. However, existing SDN architectures are centralized and then cannot meet the requirements of both scalability and adaptability simultaneously. The way in which they have typically been constructed is often very inflexible due to the risk of bottlenecks. Issues are that SDN architectures must be able to scale to billions of nodes, able to adapt to dynamic conditions, must be highly available, secure and should require minimal human configuration and management. Therefore, new architectures are required and need to be highly flexible with self-organizing capabilities in order to cope with a dynamically changing environment. In this paper, a decentralized architecture is introduced. Design concepts are presented to highlight its operation modes.

朝着去中心化和自适应的软件定义网络架构发展

软件定义网络(SDN)是一种新兴的可编程网络构建技术，是简化网络演进的一种方式。它是一种新的网络模式，其主要目的是将转发硬件与控制决策解耦。但是，现有的SDN架构过于集中化，无法同时满足可扩展性和适应性的要求。由于存在瓶颈风险，它们的构造方式通常非常不灵活。问题是SDN架构必须能够扩展到数十亿个节点，能够适应动态条件，必须是高可用性的，安全的，并且应该需要最少的人力配置和管理。因此，需要新的体系结构，并且需要具有高度灵活的自组织能力，以应对动态变化的环境。本文介绍了一种去中心化的体系结构。提出设计理念，突出其运行方式。
