SDN Networking

Software Defined Network.  A recent technological development in the world of cloud networking.  Software Defined Network involves various components - virtual switches, SDN controller and tunneling encapsulation protocols (e.g. GRE, VXLAN, STT) - in order to deliver encapsulated network traffic over (possibly) a single VLAN.  The various tunneling protocols can provide tenant (traffic) isolation.  This approach to cloud networking simplifies the layer 2 management within physical switches, enhances the networking scalability allows for central (high level) network orchestration to be handled by the overall cloud orchestration engines.
