Multicast Protocol for Low power and Lossy Networks (MPL)
draft-ietf-roll-trickle-mcast-04
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.
