Abstract

Although cloud computing and the Software Defined Network (SDN) framework are fundamentally changing the way we think about network services, multi-domain and multi-technology problems are not sufficiently investigated. These multi-domain, end-to-end problems concern communication paths that span from the wireless access and the wireless backhaul networks to the IT resources through optical networks. In this paper we present the CONTENT project approach to network and infrastructure virtualization over heterogeneous, wireless and metro optical networks, that can be used to provide end-to-end cloud services. The project goal is to drive innovation across multi-technology infrastructures and allow ICT to be delivered and consumed as a service by Virtual Network Operators. The communication mechanics between wireless and optical domains and the physical layer abstractions of a CONTENT Virtual Network are presented and the relation of the proposed approach with the SDN framework is investigated.
内容项目:对基于云的互联网络范式的考虑
尽管云计算和软件定义网络(SDN)框架从根本上改变了我们对网络服务的看法,但对多领域和多技术问题的研究还不够充分。这些多域、端到端问题涉及到从无线接入和无线回程网络到通过光网络的IT资源的通信路径。在本文中,我们提出了CONTENT项目方法,通过异构、无线和城域光网络实现网络和基础设施虚拟化,可用于提供端到端云服务。该项目的目标是推动跨多技术基础设施的创新,并允许虚拟网络运营商将ICT作为服务交付和消费。介绍了CONTENT虚拟网络的无线、光域通信机制和物理层抽象,并研究了该方法与SDN框架的关系。
