Virtual Customer Premises Equipment (vCPE) is a technology that enables network providers to implement a network functionality, such as firewalling, virtual private network (VPN), and so on, through software as opposed to the traditional way of using hardware equipment. Service providers benefit from using vCPE as it drastically simplifies management of the network services.


A virtual CPU (vCPU) is a central processing unit assigned to a virtual machine that maps to a physical CPU.


A Virtual Logical Area Network (VLAN) is an abstraction level that enables network administrators to combine ports from different switches in a logical Ethernet segment.


Virtual Networking Computing (VNC) is software that enables computer users remotely control other computer over network.


Virtual Network Function (VNF) is a network functionality, such as firewalling, domain name service, and so on that has been traditionally performed by network hardware, but is now transformed into a software function. VNF simplifies network management and makes it extremely flexible.


Virtual Private Cloud (VPC) is a collection of networking, computing, and storage resources available to end user on-demand. Typically, VPC is a part of the service provider’s private cloud. The service provider configures a VPC according to customer requirements and ensures secure access and data integrity inside the VPC.


Virtual Extensible LAN (VXLAN) is a virtualization technology that enables network administrators to provide an overlay network on top of existing network infrastructure. Compared to traditional VLAN, VXLAN provides more flexibility, as well as allows to use networks more efficiently.
