    Abstract 

       Several IETF drafts relate to the use of overlay networks to support 
       large scale virtual data centers. This draft provides a framework 
       for Network Virtualization over L3 (NVO3) and is intended to help 
       plan a set of work items in order to provide a complete solution 
       set. It defines a logical view of the main components with the 
       intention of streamlining the terminology and focusing the solution 
       set.
