Abstract

Network virtualization is a fundamental technology for datacenters and upcoming wireless communications (e.g., 5G). It takes advantage of software-defined networking (SDN) that provides efficient network management by converting networking fabrics into SDN-capable devices. Moreover, white-box switches, which provide flexible and fast packet processing, are broadly deployed in commercial datacenters. A white-box switch requires a specific and restricted packet processing pipeline; however, to date, there has been no SDN-based network hypervisor that can support the pipeline of white-box switches. Therefore, in this paper, we propose WhiteVisor: a network hypervisor which can support the physical network composed of white-box switches. WhiteVisor converts a flow rule from the virtual network into a packet processing pipeline compatible with the white-box switch. We implement the prototype herein and show its feasibility and effectiveness with pipeline conversion and overhead.
白色遮阳板:在基于sdn的网络管理程序中支持白盒交换机
网络虚拟化是数据中心和即将到来的无线通信(例如5G)的基础技术。它利用软件定义网络(SDN),通过将网络结构转换为支持SDN的设备来提供高效的网络管理。此外,提供灵活、快速数据包处理的白盒交换机在商业数据中心得到了广泛部署。白盒交换机需要特定且受限的数据包处理管道;然而,到目前为止,还没有基于sdn的网络管理程序能够支持白盒交换机的管道。因此,在本文中,我们提出了WhiteVisor:一个可以支持由白盒交换机组成的物理网络的网络管理程序。WhiteVisor将虚拟网络中的流规则转换为与白盒交换机兼容的包处理管道。我们在此实现了原型,并通过管道转换和开销验证了其可行性和有效性。
