On Demand Mobility Management
draft-ietf-dmm-ondemand-mobility-17
Abstract
Applications differ with respect to whether they need 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, as described in [RFC7333]. This
document defines a new concep of enabling applications to influence
the network's mobility services (session continuity and/or IP address
reachability) on a per-Socket basis, and suggests extensions to the
networking stack's API to accomodate this concept.

1. Introduction
In the context of Mobile IP [RFC5563][RFC6275][RFC5213][RFC5944], the
following two attributes are defined for IP service provided to
mobile hosts:
- Session Continuity
The ability to maintain an ongoing transport interaction by keeping
