Virtual Switches

At the center of networking with vSS is the virtual switch itself. The vSS can send network traffic between virtual machines on the same host (private network) or network traffic to an external network (public network). The public network uses the Ethernet adapter associated with the physical host (uplink adapter).

When two or more virtual machines are connected to the same vSS, network traffic between them is routed locally. If an uplink adapter is attached to the vSS, each virtual machine can access the external network that the adapter is connected to.
