With Windows Server 2012, Microsoft announced a first stack to set up SDN using the network virtualization using Generic Routing Encapsulation (GRE) Protocol. It attempts to solve the issues in large deployments and works at the layer 2 and layer 3 networking level. The technology was developed by Microsoft, and it was a first step to go with SDN networks.
With Windows Server 2016, Microsoft switched to a better-known and industry-wide defined standard for SDN, called Virtual Extensible LAN (VXLAN). It used a technology that is more or less similar to the encapsulation technology for VLANs using the networking level 4 instead of using VXLAN tunnel endpoints (VTEPs). VXLAN is a development to be standardized on an overlay encapsulation protocol with the result that it increases scalability for up to 16 million logical networks and allows layer 2 features across IP networks. It has been developed by VMware, Arista, and Cisco.
