This document defines distributed mobility anchoring in terms of the
different configurations and functions to provide IP mobility
support. A network may be configured with distributed mobility
anchoring functions for both network-based or host-based mobility
support, depending on the network's needs. In a distributed mobility
anchoring environment, multiple anchors are available for mid-session
switching of an IP prefix anchor. To start a new flow or to handle a
flow not requiring IP session continuity as a mobile node moves to a
new network, the flow can be started or restarted using an IP address
configured from the new IP prefix anchored to the new network. If the
flow needs to survive the change of network, there are solutions that
can be used to enable IP address mobility. This document describes
different anchoring approaches, depending on the IP mobility needs,
and how this IP address mobility is handled by the network.

This document is a product of the Distributed Mobility Management Working Group of the IETF.
