  • network hypervisor

    A network hypervisor is a program that provides an abstraction layer for network hardware.  Network hypervisors allow network engineers to create virtual networks that are completely decoupled and independent from the underlying physical network. 

  • programmable network (PN)

    A programmable network is one in which the behavior of network devices and flow control is handled by software that operates independently from network hardware. 

  • Nicira Network Virtualization Platform (Nicira NVP)

    Nicira NVP is network virtualization software that manages an abstraction layer between end systems and the physical network infrastructure and enables the creation of independently operable virtual networks. 

  • network functions virtualization (NFV)

    Network functions virtualization (NFV) is an initiative to virtualize network functions previously carried out by dedicated hardware. 

  • Mininet

    Mininet is a software emulator for prototyping a large network on a single machine.  

  • NVGRE (Network Virtualization using Generic Routing Encapsulation)

    NVGRE (Network Virtualization using Generic Routing Encapsulation) is a network virtualization method that uses encapsulation to create large numbers of virtual LANs (VLANs) for subnets that can extend across dispersed data centers and Layers 2 and ... 

  • VXLAN gateway (Virtual Extensible VLAN gateway)

    A VXLAN gateway is a solution that allows a virtual extensible LAN (VXLAN) to communicate with another network, particularly a virtual LAN (VLAN). 

About SDN network virtualization

SDN makes network virtualization possible in completely new ways. Learn how SDN will be used for dynamic network virtualization provisioning in this topic section. We'll explore how SDN will be used to control network software overlays and virtual switches. You'll also learn about network virtualization that goes beyond the data center into the WAN and LAN. Also learn about how SDN will play a key role in cloud multi-tenant networks with our news, expert advice, tips and more.
