Service Oriented Resource Management in Network Virtualization Environments

网络虚拟化提供了一种强大的方式来同时在共享的底层上运行多个网络，每个网络都针对特定目的进行了定制。研究界面临的关键挑战之一是如何通过重用物理或逻辑资源来更好地利用网络基础设施中的所有元素。为此，通过聚合多种资源，网络运营商和服务提供商能够提供范围广泛的新功能和服务。该项目的目标是在网络虚拟化领域开展研究活动，并开发解决方案，以帮助克服目前全球互联网架构的局限性。它将探索基于网络基础设施提供商、虚拟网络提供商和服务提供商分离的商业模式的新的虚拟网络体系结构。在此业务模型中，我们预计可以利用共享公共物理基础设施的优势动态创建新的协议、服务和可能的体系结构。这一方法符合所有部门的主要参与者都同意的发展现有网络的愿景。因此，运营商将受益于运营成本的降低；服务提供商将通过轻松和统一地访问网络资源而受益；最终用户将逐渐认识到网络基础设施和服务的简化使用。为了实现项目目标，渥太华大学将与高等技术学院(ETS)和爱立信加拿大公司合作，在四个主要活动中提供必要的努力，以开展网络虚拟化研究：(I)新型网络虚拟化架构，(Ii)资源发现和分配，(Iii)控制、管理和性能监测，(Iv)保护质量。将开展概念验证活动，以展示研究的价值。

Network virtualization offers a powerful way to operate multiple networks, each customized to a specific purpose, at the same time over a shared substrate. One of the key challenges facing the research community is how to better utilize all elements in the network infrastructure by means of reusing a physical or logical resource. To this end, by aggregating multiple resources, network operators and service providers are able to offer a great range of new functionalities and services. The objective of this project is to carry out research activities in the area of network virtualization and develop solutions to help overcome the limitation of the current world-wide Internet architecture. It will explore new virtual network architecture based on a business model that separates between network infrastructure providers, virtual network providers and service providers. From this business model, we expect that new protocols, services, and possibly architectures can be dynamically created with the advantage of sharing a common physical infrastructure. This approach is inline with the vision for the evolution of current networks, agreed by the major players of all sectors. As a result operators shall benefit from reduced OPEX; service providers will gain through easy and unified access to network resources; and end-users will come to appreciate the simplified use of the network infrastructure and services. To achieve the project objectives, the University of Ottawa jointly with École des Technologies Superieure (ETS) and Ericsson Canada will provide the necessary effort to carry out network virtualization research in four main activities: (i) Novel network virtualization architecture, (ii) Resources discovery and allocation, (iii) Control, Management and Performance Monitoring, (iv) Quality of Protection. A proof of concept activity will be developed to demonstrate the value of the research.
