Abstract
Applications differ with respect to whether they need IP session
continuity and/or IP address reachability. The network providing the
same type of service to any mobile host and any application running
on the host yields inefficiencies. This document describes a
solution for taking the application needs into account in selectively
providing IP session continuity and IP address reachability on a per-
socket basis.

1. Introduction
In the context of Mobile IP [RFC5563][RFC6275][RFC5213][RFC5944],
following two attributes are defined for the IP service provided to
the mobile hosts:
IP session continuity: The ability to maintain an ongoing IP session
by keeping the same local end-point IP address throughout the session
despite the mobile host changing its point of attachment within the
IP network topology. The IP address of the host may change between
two independent IP sessions, but that does not jeopardize the IP
