       Multicast Protocol for Low power and Lossy Networks (MPL)
                    draft-ietf-roll-trickle-mcast-12

Abstract

   This document specifies the Multicast Protocol for Low power and
   Lossy Networks (MPL) that provides IPv6 multicast forwarding in
   constrained networks.  MPL avoids the need to construct or maintain
   any multicast forwarding topology, disseminating messages to all MPL
   Forwarders in a MPL Domain.

   MPL has two modes of operation.  One mode uses the Trickle algorithm
   to manage control- and data-plane message transmissions, and is
   applicable for deployments with few multicast sources.  The other
   mode uses classic flooding.  By providing both modes and
   parameterization of the Trickle algorithm, a MPL implementation can
   be used in a variety of multicast deployments and can trade between
   dissemination latency and transmission efficiency.
