I-D Action:draft-ietf-rmt-pi-alc-revised-06.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Reliable Multicast Transport Working Group of the IETF.

	Title           : Asynchronous Layered Coding (ALC) Protocol Instantiation
	Author(s)       : M. Luby, et al.
	Filename        : draft-ietf-rmt-pi-alc-revised-06.txt
	Pages           : 31
	Date            : 2008-11-01

This document describes the Asynchronous Layered Coding (ALC)
protocol, a massively scalable reliable content delivery protocol.
Asynchronous Layered Coding combines the Layered Coding Transport
(LCT) building block, a multiple rate congestion control building
block and the Forward Error Correction (FEC) building block to
provide congestion controlled reliable asynchronous delivery of
content to an unlimited number of concurrent receivers from a single
sender.  This document obsoletes RFC3450.

I-D Action:draft-ietf-rmt-sec-discussion-03.txt


A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Reliable Multicast Transport Working Group of the IETF.

	Title           : Security and Reliable Multicast Transport Protocols: Discussions and Guidelines
	Author(s)       : B. Adamson, et al.
	Filename        : draft-ietf-rmt-sec-discussion-03.txt
	Pages           : 27
	Date            : 2008-11-03

This document describes general security considerations for the
Reliable Multicast Transport (RMT) Working Group set of building
blocks and protocols.  An emphasis is placed on risks that might be
resolved in the scope of transport protocol design.  However,
relevant security issues related to IP Multicast control-plane and
other concerns not strictly within the scope of reliable transport
protocol design are also discussed.  The document also begins an
exploration of approaches that could be embraced to mitigate these
risks.  The purpose of this document is to provide a consolidated
security discussion and provide a basis for further discussions and
potential resolution of any significant security issues that may
exist in the current set of RMT standards.

I-D ACTION:draft-ietf-rmt-simple-auth-for-alc-norm-00.txt


A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Reliable Multicast Transport Working Group of the IETF.

	Title		: Simple Authentication Schemes for the ALC and NORM Protocols
	Author(s)	: V. Roca
	Filename	: draft-ietf-rmt-simple-auth-for-alc-norm-00.txt
	Pages		: 27
	Date		: 2008-10-27
	
This document introduces two schemes that provide a per-packet
   authentication and integrity service in the context of the ALC and
   NORM protocols.  The first scheme is based on digital signatures.
   Because it relies on asymmetric cryptography, this scheme generates a
   high processing load at the sender and to a lesser extent at a
   receiver, as well as a significant transmission overhead.  It is
   therefore well suited to low data rate sessions.  The second scheme
   relies on a group Message Authentication Code (MAC).  Because this
   scheme relies symmetric cryptography, MAC calculation and
   verification are fast operations, which makes it suited to high data
   rate sessions.  However it only provides a group authentication and
   integrity service, which means that it only protects against
   attackers that are not group members.

RFC 5401 on Multicast Negative-Acknowledgment (NACK) Building	Blocks



A new Request for Comments is now available in online RFC libraries.

        
        RFC 5401

        Title:      Multicast Negative-Acknowledgment (NACK) Building 
                    Blocks 
        Author:     B. Adamson, C. Bormann,
                    M. Handley, J. Macker
        Status:     Standards Track
        Date:       November 2008
        Mailbox:    adamson <at> itd.nrl.navy.mil, 
                    cabo <at> tzi.org,

        Pages:      42
        Characters: 109312
        Obsoletes:  RFC3941

        I-D Tag:    draft-ietf-rmt-bb-norm-revised-07.txt

        URL:        http://www.rfc-editor.org/rfc/rfc5401.txt

This document discusses the creation of reliable multicast protocols
that utilize negative-acknowledgment (NACK) feedback.  The rationale
for protocol design goals and assumptions are presented.  Technical
challenges for NACK-based (and in some cases general) reliable
multicast protocol operation are identified.  These goals and
challenges are resolved into a set of functional "building blocks"
that address different aspects of reliable multicast protocol
operation.  It is anticipated that these building blocks will be
useful in generating different instantiations of reliable multicast
protocols.  This document obsoletes RFC 3941.  [STANDARDS TRACK]

This document is a product of the Reliable Multicast Transport Working Group of the IETF.

This is now a Proposed Standard Protocol.

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 Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol.  Distribution of this memo is unlimited.
