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.
