Internet-Draft   Multicast deployment scenario over DMM   October 2016

Abstract

   This document presents deployment scenarios for supporting IP
   multicast over distributed mobility management (DMM) architecture,
   which considers the separation of the control and the data planes.
   This document describes three main use cases of IP multicast
   deployments over DMM depending on the placement of control and data
   plane functional entities.

1. Introduction

   Distributed mobility management is a new paradigm to solve current
   problems of centralized mobility management, such as a single point
   of failure, non-optimal routing [RFC7333].

   IP multicast is an efficient content distribution mechanism which is
   designed with the IP mobility to bring new user experience and
   reduce bandwidth cost. In the [RFC7333], one requirement for DMM is
   to enable multicast solutions to avoid the inefficiency in the
   multicast traffic delivery.

   Existing solutions for supporting multicast in DMM are bi-
   directional tunnel [TUNNEL] and direct routing [ROUTING]. These
   solutions focus on the placement of MLD proxy and multicast router
   functions into the Mobility Access Router.

   The current architecture of the DMM is being changed to employ the
   concept of data and control plane separation. The data plane nodes

   are configured by the control nodes via Forwarding Policy
   Configuration protocol, as defined in [I-D.ietf-dmm-fpc-cpdp]. The
   several deployment scenarios were presented in
   [I-D.wt-dmm-deployment-model].

   However, there is no work until now, mentioning about multicast
   support in such new DMM architectures. Therefore, this document
