In this video, learn about the definition of software-defined networking and its components. SDN allows administrators to use SDN to segment network traffic in virtual environments.
- Software-Defined Networking provides a method to centrally configure and manage physical and virtual network devices. Such as routers, switches and gateways in your network. Virtual network elements, such as Hyper-V virtual switch, Hyper-V network virtualization, and Windows Server Gateway, are designed to be important elements of your Software-Defined Networking infrastructure. While you can still use your existing physical switches, routers, and other hardware, you can achieve deeper integration between the virtual network, and the physical network, if these devices are designed for compatibility with Software-Defined networking.
There are some new features in Windows Server 2016; Network controller provides a centralized programmable point of automation, to manage, configure, monitor and troubleshoot both virtual and physical network infrastructure in your data center. You can now automate your configuration of network infrastructure, instead of performing manual configurations. Windows Server 2016 delivers Hyper-V network virtualization. And that helps you separate your apps, and work loads from the physical network using virtual networks.
Virtual networks provide the necessary multi-tenant isolation, while running on a shared physical network fabric. This allows you to drive up resource utilization, and it ensures that you can carry forward your existing investments. Virtual networks can be set on existing network gear, and are compatible with vLance. The Hyper-V virtual switch is a software based layer two ethernet network switch, that's available in Hyper-V manager when you install the Hyper-V server role.
You can connect virtual machines to both virtual networks, and the physical network. In addition, Hyper-V virtual switch provides policy enforcement for security, isolation and service levels. You can use the routing and remote access multitenant gateway for several different things. It helps you move your work loads within and across data centers and clouds. It also includes a software edge gateway we'll be discussing in upcoming videos, that can be managed by System Center 2016.
The gateway helps you easily extend your data center boundaries to a service provider, or Windows Azure. NIC teaming, also known as load bouncing and failover, allows multiple network adapters on a computer to be placed into a team, for the following purposes; bandwidth aggregation and traffic failover to prevent connectivity loss in the event of a network component failure. We will be talking about, and demonstrating all these different terms in upcoming videos.
Software-Defined Networking is an excellent way for administrators to segment traffic in their network without the need for additional routers and switches, which can save the company money and time.
Note: This course is the first of two that will cover SDN in a Server 2016 network. This course maps to the SDN deployment objectives in Exam 70-745.
- Planning an SDN
- Configuring a Hyper-V switch
- Creating network objects in Virtual Machine Manager
- Creating IP pools and VM networks
- Creating logical switches and uplink ports
- Configuring an edge gateway
- Creating multitenant VMs
