Internet-Draft         Multicast Anchoring in DMM         October 2016

Abstract

   In this draft, we define multicast support functions in a
   Distributed Mobility Management (DMM) environment. Based on the
   decomposed mobility management functions in [RFC7429], each defined
   multicast support function can be located and operated with DMM
   functions.

1. Introduction

   Based on [RFC7333], a multicast solution in Distributed Mobility
   Management (DMM) should be considered early in the process of
   designing protocol and deployment models. Multicast support in DMM
   should avoid inefficient methods, such as non-optimal forwarding or
   tunnel convergence.

   To support IP multicasting, we need several functions: a multicast
   routing protocol, membership management, etc. When we consider
   multicast support in DMM, we should determine how efficiently these
   functions can be operated with the mobility management functions in
   DMM. Possible use cases are already described in [Use Case for
   Multicast DMM]. However, since current DMM research considers
   control/data separation and functional decomposition, we need to
   define multicast support functions following decomposed DMM anchor
   functions and operate with them.

   In this draft, we define multicast mobility management functions
   that enable us to deploy the DMM functions defined in [RFC7429]. We
   define multicast mobility management functions in a similar way
   because it is easier to deploy multicast mobility management
