Boeing Technology Innovation Mobile nodes that operate in air/land/sea/space domains (e.g., aircraft of various configurations, terrestrial vehicles, seagoing vessels, space systems, enterprise wireless devices, pedestrians with cell phones, etc.) configure mobile routers to connect end user network peers with Internetwork correspondents over wireless and/or wired-line data links. This document presents a multilink virtual interface specification that supports mobile node coordination with a network-based mobility service, fixed node correspondents and/or other mobile node peers. The virtual interface provides an adaptation layer service that supports secure global mobile Internetworking. This document specifies the transmission of IP packets over Overlay Multilink Network (OMNI) Interfaces.
