Network Virtualization decouples virtual networks andaddresses from physical network infrastructure, providing isolationand concurrency between multiple virtual networks on the samephysical network infrastructure. This document also introduces aNetwork Virtualization framework to illustrate the use cases, butthe focus is on specifying the data-plane aspect of NVGRE.
