网络虚拟化互通技术

Network Virtualization Interconnection Technology

工业界和学术界提出了许多新的网络虚拟化技术来满足云计算环境对网络服务的需求。网络虚拟化技术的多样化使得云环境而临多种网络虚拟化技术共存的状况。然而,网络虚拟化技术问的差异会导致网络资源被分割成相互间不可通信的"孤岛"。为了解决这个问题,提出了网络虚拟化互通技术,分析了该技术的实现难点,并提出了基于软件定义网络的网络虚拟化互通架构Omni-Bridge,最后给出了Omni-Bridge的原型实现和功能验证。

Industry and the Academia have carried out various kinds of network virtualization technologies to cope with the growing requirement of cloud network. The diversity in network virtualization technologies will lead to the co-existence of various kinds of technologies in cloud environment. However, the differences among network virtualization technologies separate the overall network resources into several isolated ＂islands＂. In order to solve the problem, a solution called network virtualization interconnection technology was introduced. The key challenges of realizing the interconnection were discussed, then a novel software defined networking based interconnection architecture 0mni-Bridge was proposed. Finally, a prototype of 0toni-Bridge was introduced and a functional validation experiment was presented.
