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
