Abstract

   Mobile nodes (e.g., aircraft of various configurations, terrestrial
   vehicles, seagoing vessels, enterprise wireless 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 presented that
   enables mobile nodes to coordinate with a network-based mobility
   service and/or with other mobile node peers.  This document specifies
   the transmission of IP packets over Overlay Multilink Network (OMNI)
   Interfaces.
