System Center - Virtual Machine Manager (VMM) 可用于部署和管理软件定义网络 (SDN) 基础结构。System Center - Virtual Machine Manager (VMM) can be used to deploy and manage a Software Defined Network (SDN) infrastructure.

软件定义网络概述Software Defined Network overview

SDN 对网络进行虚拟化来抽象物理硬件网络元件,如交换机和路由器。SDN virtualizes your network to abstract physical hardware network elements such as switches and routers. 使用 SDN 可以动态地管理数据中心网络连接,以满足工作负荷和应用要求。Using SDN you can dynamically manage your datacenter networking to meet workload and app requirements. 可以大规模一致地实施网络策略,甚至在部署新的工作负荷、跨虚拟或物理网络移动工作负荷时仍可以。Network policies can be implemented consistently, at scale, even as you deploy new workloads, or move workloads across virtual or physical networks.

如果在 VMM 构造中部署 SDN,你可以:If you deploy SDN in the VMM fabric you can:

  • 大规模地配置和管理虚拟网络。Provision and manage virtual networks at scale.
  • 部署和管理 SDN 基础结构,包括网络控制器、软件负载平衡器以及网关。Deploy and manage the SDN infrastructure, including network controllers, software load balancers, and gateways.
  • 集中定义和控制虚拟网络策略并将其链接到应用程序或工作负荷。Define and control virtual network policies centrally and link them to your applications or workloads. 在部署或移动工作负荷时,网络配置将自动对自身进行调整。When your workload is deployed or moved, the network configuration adjusts itself automatically. 这很重要,因为它不再需要手动重新配置网络硬件,从而减少操作复杂性,同时节省宝贵的资源以用于影响较大的工作。This is important because it removes the need for manual reconfiguration of network hardware, thereby reducing operational complexity while saving your valuable resources for higher-impact work.
  • 控制虚拟网络之间的通信流,包括能够针对关键应用程序和工作负荷定义有保证的带宽。Control traffic flow between virtual networks, including the ability to define guaranteed bandwidth for your critical applications and workloads.

SDN 组合了多种技术,其中包括:SDN combines a number of technologies, among them:

  • 网络控制器:网络控制器使你能够自动执行网络基础结构配置,而不是手动配置网络设备和服务。Network Controller:The network controller allows you to automate configuration of your network infrastructure, instead of manually configuring network devices and services.
  • 用于 SDN 的 RAS 网关:RAS 网关是 Windows Server 2016 中基于软件的、支持 BGP 的多租户路由器,专门为使用 HNV 托管多个租户虚拟网络的 CSP 和企业设计。RAS Gateway for SDN: RAS Gateway is a software-based, multitenant, BGP capable router in Windows Server 2016 that is designed for CSPs and Enterprises that host multiple tenant virtual networks using HNV.
  • 用于 SDN 的软件负载平衡 (SLB) :Windows Server 2016 中的 SDN 可以使用软件负载平衡 (SLB) 在虚拟网络资源之间均匀分配租户和租户客户网络流量。Software Load Balancing (SLB) for SDN: (SDN) in Windows Server 2016 can use Software Load Balancing (SLB) to evenly distribute tenant and tenant customer network traffic among virtual network resources. Windows Server SLB 允许多台服务器托管相同的工作负荷,从而提供高可用性和可伸缩性。The Windows Server SLB enables multiple servers to host the same workload, providing high availability and scalability.
