From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: Internet Architecture Board <firstname.lastname@example.org>, RFC Editor <email@example.com>, rmt mailing list <firstname.lastname@example.org>, rmt chair <email@example.com> Subject: Protocol Action: 'Layered Coding Transport (LCT) Building Block' to Proposed Standard The IESG has approved the following document: - 'Layered Coding Transport (LCT) Building Block ' <draft-ietf-rmt-bb-lct-revised-11.txt> as a Proposed Standard This document is the product of the Reliable Multicast Transport Working Group. The IESG contact persons are Magnus Westerlund and Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-rmt-bb-lct-revised-11.txt
Technical Summary This document is an RMT Building Block that specifies protocol headers and procedures useful for building a reliable multicast transport protocol that can employ packet-level forward error correction (FEC) coding to enable massively- scalable, reliable, unidirectional network data transport without requiring receiver feedback. Layered Coding Transport is specifically designed to support protocols using IP multicast, but also provides support to protocols that use unicast. Layered Coding Transport is compatible with congestion control that provides multiple rate delivery to receivers. Working Group Summary There is consensus in the WG to publish this documents. Document Quality The document is of high quality and has been subject to extensive review in its Internet Draft and Experimental RFC forms. The revised draft represents a small number of changes from the original Experimental RFC 3451. Open source implementations of the LCT protocol are available and considerable experience in using this protocol has been accumulated. The protocol has been adopted by the Digital Video Broadcasting (DVB) industry consortium for content delivery. The content of this document was already reviewed and approved for publication as experimental RFC 3451. This document contains minor technical modifications. Personnel Brian Adamson is the Document Shepherd. Magnus Westerlund is the Responsible Area Director.
