       Multicast Protocol for Low power and Lossy Networks (MPL)
                    draft-ietf-roll-trickle-mcast-05

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 an MPL Domain.  MPL uses the Trickle algorithm to
   manage message transmissions for both control and data-plane
   messages.  Different Trickle parameter configurations allow MPL to
   trade between dissemination latency and transmission efficiency.
