IP Mobility Support for IPv4
RFC 3220, “IP Mobility Support for IPv4”, is a Proposed Standard document published in January 2002 by C. Perkins. It obsoletes RFC 2002. It has been obsoleted by RFC 3344 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document specifies protocol enhancements that allow transparent routing of IP datagrams to mobile nodes in the Internet. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about its current point of attachment to the Internet. The protocol provides for registering the care-of address with a home agent. The home agent sends datagrams destined for the mobile node through a tunnel to the care-of address. After arriving at the end of the tunnel, each datagram is then delivered to the mobile node. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
