   Transmission of IPv6 Packets over Overlay Multilink Network (OMNI)
                               Interfaces

Abstract

   Mobile nodes (e.g., aircraft of various configurations, terrestrial
   vehicles, seagoing vessels, mobile enterprise devices, etc.)
   communicate with networked correspondents over multiple access
   network data links and configure mobile routers to connect end user
   networks.  A multilink interface specification is therefore needed
   for coordination with the network-based mobility service.  This
   document specifies the transmission of IPv6 packets over Overlay
   Multilink Network (OMNI) Interfaces.
