    abstract =  {We describe a framework for policy-based, software controlled network virtualization to support multitenancy in public and private clouds using Generic Routing Encapsulation (GRE). The framework outlined in this document can be used by cloud hosters, enterprise data centers and enables seamless migration of workloads between public and private clouds. This document is focused on the data plane aspects of the NVGRE framework.},
