Network virtualization algorithm engine

互联网最初是创新的温床。其主要设计目标之一是允许研究人员尝试新的和破坏性的想法。但是，沿着，它惊人的成功和受欢迎程度已造成这一非常重要的目标被靠边站。由于存在多个利益相关者，而且往往有相互冲突的目标，对现有互联网进行重大改造几乎是不可能的。网络虚拟化最近被提出作为一种手段来抵御这种僵化。其主要思想是在单个物理网络上容纳多个逻辑（虚拟）网络。虚拟网络的所有者可以自由地部署任何通信协议或服务。通过允许多个异构网络共存于一个共享的物理网络上，网络虚拟化的目标是提供灵活性、多样性、安全性和可扩展性。然而，这是有代价的。需要应对若干新的挑战。为此，最近的研究充其量可以被描述为试图解决当前互联网的一些现有问题，而不是建立一个完整的网络虚拟化环境（NVE）的协调努力。在这个项目中，我们专注于三个方面，这是一个NVE的实例化和操作的核心重要性，i）可扩展性，ii）故障恢复能力和iii）虚拟网络管理在一个多层的生产网络。与我们的工业合作伙伴华为合作在这些研究领域取得的进展可能会对未来互联网的设计原则和管理模式产生持久的影响。

The Internet started out as a breeding ground for innovation. One of its main design goals was to allow researchers to try out new and disruptive ideas. But, along the way, its amazing success and popularity has caused this very important objective to be sidelined. Due to the existence of multiple stakeholders, often with conflicting goals, major alterations to the existing Internet are next to impossible. Network virtualization has recently been propounded as a means to fend off this ossification. The main idea is to accommodate multiple logical (virtual) networks on a single physical network. The owner of a virtual network is free to deploy any communication protocol or service. By allowing multiple heterogeneous networks to cohabit on a shared physical one, the goal of network virtualization is to provide flexibility, diversity, security and manageability. However, this comes at a cost. Several new challenges need to be addressed. Recent research, to this end, can at best be described as attempts to fix some existing, and mostly disjoint, problems of the current Internet, rather than a coordinated effort to build a complete Network Virtualization Environment (NVE). In this project, we focus on three aspects that are of central importance to the instantiation and operation of an NVE, i) scalability, ii) failure resilience and iii) virtual networks management in a multi-layer production network. Advances in these research avenues in collaboration with our industrial partner Huawei could have a lasting impact on the design principles and management paradigms of the future Internet.
