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