Abstract

The combination of emerging concepts, such as Fog Computing, Software Defined Networking and Network Function Virtualization will contribute to transform the network into a flexible and dynamical continuum of resources, on which services can be easily deployed and managed (network programmability). In this scenario, a major topic is the use of ad hoc h/w accelerators, in particular to provide the network with general purpose High Performance Computing capabilities, whose application has been so far limited to few highly specialized contexts, such as graphics or scientific computing. However, the use of h/w acceleration is generally considered in contrast with the main NFV concepts, and a major obstacle towards network programmability. This paper argues that, on the contrary, h/w acceleration and virtualization technologies are fully compatible, and together can greatly enhance the network infrastructure. In particular, the use of Graphic Computing Units in Virtual Network Functions is analyzed, and their flexible management is considered, within the innovative NFV architecture designed by the EU FP7 T-Nova project.
高性能计算和网络功能虚拟化:网络可编程性的主要挑战
雾计算、软件定义网络和网络功能虚拟化等新兴概念的结合将有助于将网络转变为灵活和动态的资源连续体,服务可以在其上轻松部署和管理(网络可编程性)。在这种情况下,一个主要的主题是使用特别的h/w加速器,特别是为网络提供通用的高性能计算能力,其应用到目前为止仅限于少数高度专业化的环境,例如图形或科学计算。然而,h/w加速的使用通常被认为与主要的NFV概念相反,并且是网络可编程性的主要障碍。相反,本文认为h/w加速和虚拟化技术是完全兼容的,它们一起可以极大地增强网络基础设施。特别地,分析了图形计算单元在虚拟网络功能中的使用,并在欧盟FP7 T-Nova项目设计的创新NFV架构中考虑了它们的灵活管理。
