Low-Power and Lossy Networks (LLNs) typically operate with strict resource constraints in communication, computation, memory, and energy. Such resource constraints may preclude the use of existing IPv6 multicast routing and forwarding mechanisms. Traditional IP multicast delivery typically relies on topology maintenance mechanisms to discover and maintain routes to all subscribers of a multicast group (e.g., [RFC3973] [RFC4601]). However, maintaining such topologies in LLNs is costly and may not be feasible given the available resources.

        Multicast Protocol for Low-Power and Lossy Networks (MPL)


   This document specifies the Multicast Protocol for Low-Power and    Lossy Networks (MPL), which 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 has two modes of operation.  One mode uses the Trickle algorithm    to manage control-plane 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, an MPL implementation can    be used in a variety of multicast deployments and can trade between    dissemination latency and transmission efficiency.
