Title: IP Mobility Support for IPv4, revised
State: Active
Authors: Charles Perkins
Group: Mobility for IPv4 (mip4)
Date: 2004-10-25
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.
