A new Request for Comments is now available in online RFC libraries. RFC 7731 Title: Multicast Protocol for Low-Power and Lossy Networks (MPL) Author: J. Hui, R. Kelsey Status: Standards Track Stream: IETF Date: February 2016 Mailbox: jonhui@nestlabs.com, richard.kelsey@silabs.com Pages: 29 Characters: 63216 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-roll-trickle-mcast-12.txt URL: https://www.rfc-editor.org/info/rfc7731 DOI: http://dx.doi.org/10.17487/RFC7731 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. This document is a product of the Routing Over Low power and Lossy networks Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
