Transmission of IPv6 Packets over Overlay Multilink Network (OMNI)
Interfaces
draft-templin-6man-omni-interface-07
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.
