Transmission of IPv6 Packets over Overlay Multilink Network (OMNI)
Interfaces
draft-templin-atn-aero-interface-19
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.

1. Introduction
Mobile Nodes (MNs) (e.g., aircraft of various configurations,
terrestrial vehicles, seagoing vessels, mobile enterprise devices,
etc.) often have multiple data links for communicating with networked
correspondents. These data links may have diverse performance, cost
and availability properties that can change dynamically according to
mobility patterns, flight phases, proximity to infrastructure, etc.
MNs coordinate their data links in a discipline known as "multilink",
