摘要:

未来网络体系架构和关键技术的研究需要灵活开放的测试验证环境,基于传统分布式的网络架构难以达到动态虚拟化、有效管控和新协议灵活部署的需求。随着软件定义网络(SDN)技术的出现和发展,上述问题找到了有效的解决途径,因此,基于 SDN 构建网络试验床成为了近年来该领域的主流研究方向之一。其中,基于SDN的网络虚拟化切片技术更是试验床中的核心支撑技术,可以根据不同试验的需求切分物理网络资源,从而提供并行、独立的网络环境。将重点研究基于 SDN 的试验床中使用的网络虚拟化切片机制,从“流量识别和切片网络标识”、“虚拟节点抽象”和“虚拟链路抽象”这3个关键技术出发,对当前基于SDN试验床中的典型网络虚拟化切片机制进行介绍与分析,并总结了该领域未来可行的研究方向。

Abstract:

The researches on future network architecture and key logies need test environment both open and flex-ible. Traditional distribute architecture was short on effective control and new protocol deployment. The emerging of the software defined networking (SDN) technology provides a promising way to s this problem and become a major re-search direction in recent years. In the SDN based network testbed, the virtual network slicing technology was a key issue since it could separate physical resource and provided individual virtual network environment. Therefore, the slicing me-thods of some typical network virtualization platforms with the perspective of “slice identifier”, “virtual nodes ab-straction”and “virtual links abstraction”were introduced , and the future research directions were concluded in this field.

Key words: software defined networking, OpenFlow, network virtualization, testbed
