Abstract

The introduction of SDN in IP backbones requires the coexistence of regular IP forwarding and SDN based forwarding. The former is typically applied to best effort Internet traffic, the latter can be used for different types of advanced services (VPNs, Virtual Leased Lines, Traffic Engineering). In this paper we first introduce the architecture and the services of an "hybrid" IP/SDN networking scenario. Then we describe the design and implementation of an Open Source Hybrid IP/SDN (OSHI) node. It combines Quagga for OSPF routing and Open vSwitch for OpenFlow based switching on Linux. The availability of tools for experimental validation and performance evaluation of SDN solutions is fundamental for the evolution of SDN. We provide a set of open source tools that allow to facilitate the design of hybrid IP/SDN experimental networks, their deployment on Mininet or on distributed SDN research testbeds and their test. Finally, using the provided tools, we evaluate key performance aspects of the proposed solutions. The OSHI development and test environment is available in a VirtualBox VM image that can be downloaded.

开源混合IP/SDN网络(及其在Mininet和分布式SDN测试平台上的仿真)

在IP骨干网中引入SDN，要求常规IP转发和基于SDN的转发同时存在。前者通常用于“尽力而为”的互联网流量，后者可用于不同类型的高级业务(vpn、虚拟租用线路、流量工程)。在本文中，我们首先介绍了“混合”IP/SDN网络场景的体系结构和服务。然后，我们描述了一个开源混合IP/SDN (OSHI)节点的设计和实现。它结合了用于OSPF路由的Quagga和用于Linux上基于OpenFlow的交换的Open vSwitch。SDN解决方案的实验验证和性能评估工具的可用性是SDN发展的基础。我们提供了一套开源工具，可以促进混合IP/SDN实验网络的设计，在Mininet或分布式SDN研究测试平台上的部署和测试。最后，使用提供的工具，我们评估所建议的解决方案的关键性能方面。OSHI开发和测试环境在VirtualBox虚拟机映像中可用，可以下载。
