DMM Working Group A. Yegin Internet-Draft Actility Intended status: Informational D. Moses Expires: August 26, 2019 Intel S. Jeon Sungkyunkwan University February 22, 2019 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.
