     Abstract 

       This document describes Virtual eXtensible Local Area Network 
       (VXLAN), which is used to address the need for overlay networks 
       within virtualized data centers accommodating multiple tenants. The 
       scheme and the related protocols can be used in cloud service 
       provider and enterprise data center networks.
