SDN大众访问控制

SDN Access Control for the Masses

Nicolae Paladi, Christian Gehrmann

摘要:

到目前为止,软件定义网络(SDN)的演进主要面向定义和细化转发和控制平面上的抽象。然而,尽管成熟的南向接口和一系列建议的网络操作系统,网络管理应用层尚未被指定和标准化。它目前定义的访问控制机制很差,可能会暴露给网络应用程序。现有的机制只允许基本的控制,缺乏跨多个维度划分资源访问的过程。我们通过扩展SDN北向接口来解决这个问题,为网络基础设施的关键利益相关者提供对共享资源的控制:网络提供商,运营商和应用开发商。我们介绍了SDN访问模型的分类,描述了一个全面的SDN访问控制设计,并实现了所提出的解决方案作为一个扩展的ONOS网络控制器的意图框架。

英文摘要:

The evolution of Software-Defined Networking (SDN) has so far been predominantly geared towards defining and refining the abstractions on the forwarding and control planes. However, despite a maturing south-bound interface and a range of proposed network operating systems, the network management application layer is yet to be specified and standardized. It has currently poorly defined access control mechanisms that could be exposed to network applications. Available mechanisms allow only rudimentary control and lack procedures to partition resource access across multiple dimensions. We address this by extending the SDN north-bound interface to provide control over shared resources to key stakeholders of network infrastructure: network providers, operators and application developers. We introduce a taxonomy of SDN access models, describe a comprehensive design for SDN access control and implement the proposed solution as an extension of the ONOS network controller intent framework.
