Internet-Draft          MAMS u-plane protocols               March 2017

Abstract

   Today, a device can be simultaneously connected to multiple
   communication networks based on different technology implementations
   and network architectures like WiFi, LTE, DSL. In such multi-
   connectivity scenario, it is desirable to combine multiple access
   networks or select the best one to improve quality of experience for
   a user and improve overall network utilization and efficiency. This
   document presents the u-plane protocols for a multi access
   management services (MAMS) framework that can be used to flexibly
   select the best combination of uplink and downlink access and core
   network paths, and user plane treatment for improving network
   efficiency and enhanced application quality of experience.

1. Introduction

   Multi Access Management Service (MAMS) [MAMS] is a programmable
   framework to select and configure network paths, as well as adapt to
   dynamic network conditions, when multiple network connections can
   serve a client device. It is based on principles of user plane
   interworking that enables the solution to be deployed as an overlay
   without impacting the underlying networks.

   This document presents the u-plane protocols for the MAMS framework.
   It co-exists and complements the existing protocols by providing a
   way to negotiate and configure the protocols based on client and
   network capabilities. Further it allows exchange of network state
   information and leveraging network intelligence to optimize the
   performance of such protocols. An important goal for MAMS is to
   ensure that there is minimal or no dependency on the actual access
