Using VXLAN for Encapsulation and OVSDB for Policy Distribution

Windows Server 2016 is the perfect platform for building your Software-Defined Data Center (SDDC) with new layers of security and Azure-inspired innovation for hosting business applications and infrastructure. A critical piece of this SDDC is the new Software Defined Network (SDN) Stack which provides agility, dynamic security, and hybrid flexibility by enforcing network policy in the Hyper-V Virtual Switch using the Azure Virtual Filtering Platform (VFP) Switch Extension. Instead of programming network configurations into a physical switch using CLI, NetConf, or OpenFlow, the network policy is instead delivered from the new Microsoft Network Controller to the Hyper-V Hosts using the OVSDB protocol and programmed into the VFP extension of the vSwitch by a Host Agent which enforces the policy. By creating overlay virtual networks (VXLAN Tunnels / logical switches) and endpoints which terminate in the vSwitch, each Hyper-V host becomes a software VXLAN Tunnel End Point (VTEP).

Note: This will be a technical post focusing on networking protocols and some implementation details

Overlays, VXLAN, virtual networking, HNV, encapsulation, NVGRE, logical switch… why should you care about all these esoteric networking terms? Maybe you have heard hard-core networking types mention these in passing or have customers asking how Microsoft’s network virtualization solution compares with other solutions. Why should you care? Because just as compute and storage have been virtualized, traditional networking devices and services are also being virtualized for greater flexibility.
