The following table describes each component of NSX for RPC-VMware.
|NSX Manager||1||Provides an aggregated system view and is the centralized network management component of NSX. NSX Manager is installed as a virtual appliance on any ESXi host in your vCenter environment.|
|NSX Controller||3||The central control point for all logical switches within a network. Controllers maintain information about all VMs, hosts, logical switches, and VXLANs.|
|VTEP||NA||Every ESXi host enabled for NSX is configured with an additional VMkernel port used as a VXLAN Tunnel End Point (VTEP). In other words, a VTEP is a host interface that forwards Ethernet frames from a virtual network via VXLAN or vice-versa.|
|VXLAN||NA||Virtual Extensible LAN (VXLAN) is a encapsulation protocol for running an overlay network on existing layer 3 infrastructure. An overlay network is a virtual network that is built on top of existing network layer 2 and layer 3 technologies to support software defined networks.|
