软件定义网络(SDN)的分散方法

A Decentralized Approach to Software-Defined Networks (SDNs)

Reza Farrahi Moghaddam, Yves Lemieux, Mohamed Cheriet

摘要:

在软件定义网络(SDN)中重新分配智能和管理是解决这些网络的可扩展性和完整性瓶颈的潜在方法。我们建议根据区域的概念重新审视路由概念。利用区域的基本和一致的定义,提出了一种基于区域的数据包路由算法SmartRegion Routing。区域在命名和寻址方面的灵活性然后以区域堆栈的形式以及放置在相关联的分组报头中的其他特征来利用。以这种方式,网络的大部分复杂性和动态性被吸收,因此在区域间级别的高度快速和简化的路由以及半自治的区域内路由将是可行的。此外,多径规划可以自然地在帧间和帧内级别实现。提供了SmartRegion路由机制的基本形式。所提出的方法的简单性、可扩展性和可扩展性也将带来未来减少与SDN相关的能源消耗和环境足迹的潜力。最后,各种应用,如实现无缝宽带接入,提供超越IP寻址机制,也地址等效命名机制,被认为是和讨论。

英文摘要:

Redistribution of the intelligence and management in the software defined networks (SDNs) is a potential approach to address the bottlenecks of scalability and integrity of these networks. We propose to revisit the routing concept based on the notion of regions. Using basic and consistent definition of regions, a region-based packet routing called SmartRegion Routing is presented. The flexibility of regions in terms of naming and addressing is then leveraged in the form of a region stack among other features placed in the associated packet header. In this way, most of complexity and dynamicity of a network is absorbed, and therefore highly fast and simplified routing at the inter-region level along with semi-autonomous intra-region routing will be feasible. In addition, multipath planning can be naturally realized at both inter and intra levels. A basic form of SmartRegion routing mechanism is provided. Simplicity, scalability, and manageability of the proposed approach would also bring future potentials to reduce energy consumption and environmental footprint associated to the SDNs. Finally, various applications, such as enabling seamless broadband access, providing beyond IP addressing mechanisms, and also address-equivalent naming mechanisms, are considered and discussed.
