RFC 6236 on Negotiation of Generic Image Attributes in the Session Description Protocol (SDP)


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

        
        RFC 6236

        Title:      Negotiation of Generic Image Attributes 
                    in the Session Description Protocol (SDP) 
        Author:     I. Johansson, K. Jung
        Status:     Standards Track
        Stream:     IETF

        I-D Tag:    draft-ietf-mmusic-image-attributes-11.txt

        URL:        http://www.rfc-editor.org/rfc/rfc6236.txt

This document proposes a new generic session setup attribute to make
it possible to negotiate different image attributes such as image
size.  A possible use case is to make it possible for a %low-end %hand-
held terminal to display video without the need to rescale the image,
something that may consume large amounts of memory and processing
power.  The document also helps to maintain an optimal bitrate for
video as only the image size that is desired by the receiver is
transmitted.  [STANDARDS-TRACK]

I-D Action: draft-ietf-siprec-req-11.txt

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

	Title           : Use Cases and Requirements for SIP-based Media Recording (SIPREC)
	Author(s)       : Ken Rehor
                          Leon Portman
                          Andrew Hutton
                          Rajnish Jain
	Filename        : draft-ietf-siprec-req-11.txt

	Date            : 2011-05-31

   Session recording is a critical requirement in many business
   communications environments such as call centers and financial
   trading floors.  In some of these environments, all calls must be
   recorded for regulatory and compliance reasons.  In others, calls may
   be recorded for quality control or business analytics.

   Recording is typically performed by sending a copy of the session
   media to the recording devices.  This document specifies requirements
   for extensions to SIP that will manage delivery of RTP media to a
   recording device.  This is being referred to as SIP-based Media
   Recording.

I-D Action: draft-ietf-softwire-gateway-init-ds-lite-04.txt

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

	Title           : Gateway Initiated Dual-Stack Lite Deployment
	Author(s)       : Frank Brockners
                          Sri Gundavelli
                          Sebastian Speicher

	Pages           : 15
	Date            : 2011-06-01

   Gateway-Initiated Dual-Stack lite (GI-DS-lite) is a variant of Dual-
   Stack lite (DS-lite) applicable to certain tunnel-based access
   architectures.  GI-DS-lite extends existing access tunnels beyond the
   access gateway to an IPv4-IPv4 NAT using softwires with an embedded
   context identifier that uniquely identifies the end-system the
   tunneled packets belong to.  The access gateway determines which
   portion of the traffic requires NAT using local policies and sends/
   receives this portion to/from this softwire.

I-D Action: draft-ietf-tsvwg-natsupp-01.txt

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

	Title           : Stream Control Transmission Protocol (SCTP) Network Address Translation Support
	Author(s)       : Randall R. Stewart
                          Michael Tuexen
                          Irene Ruengeler
	Filename        : draft-ietf-tsvwg-natsupp-01.txt
	Pages           : 11
	Date            : 2011-06-01

   Stream Control Transmission Protocol [RFC4960] provides a reliable
   communications channel between two end-hosts in many ways similar to
   TCP [RFC0793].  With the widespread deployment of Network Address
   Translators (NAT), specialized code has been added to NAT for TCP
   that allows multiple hosts to reside behind a NAT and yet use only a
   single globally unique IPv4 address, even when two hosts (behind a
   NAT) choose the same port numbers for their connection.  This
   additional code is sometimes classified as Network Address and Port
   Translation or NAPT.  To date, specialized code for SCTP has NOT yet
   been added to most NATs so that only pure NAT is available.  The end
   result of this is that only one SCTP capable host can be behind a
   NAT.

   This document describes an SCTP specific chunks and procedures to
   help NAT&#39;s provide similar features of NAPT in the single point and
   multi-point traversal scenario.

I-D Action: draft-ietf-xcon-common-data-model-29.txt

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

	Title           : Conference Information Data Model for Centralized Conferencing (XCON)
	Author(s)       : Oscar Novo
                          Gonzalo Camarillo
                          David P. Morgan
                          Jari Urpalainen
	Filename        : draft-ietf-xcon-common-data-model-29.txt
	Pages           : 96
	Date            : 2011-06-01

   RFC5239 defines the idea of a centralized conferencing (XCON) as an
   association of participants with a central focus.  The state of a
   conference is represented by a conference object.  This document
   defines an Extensible Markup Language (XML)-based conference
   information data model to be used for conference objects.  A
   conference information data model is designed to convey information
   about the conference and about participation in the conference.  The
   conference information data model defined in this document
   constitutes an extension of the data format specified in the Session
   Initiation Protocol (SIP) Event Package for Conference State.

I-D Action: draft-schmidt-mmusic-sdp-local-identifier-01.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title           : SDP Local Identifier
	Author(s)       : Mischa Schmidt
                          Hans-Joerg Kolbe
                          Martin Stiemerling
	Filename        : draft-schmidt-mmusic-sdp-local-identifier-01.txt
	Pages           : 12
	Date            : 2011-06-01

   Dynamic Policy Controllers like resource and admission control
   systems need to be able to locate media receivers in each segment of
   the network to determine the path of the media flows prior to
   allowing or rejecting the session setup.  This is fine as long as
   this is handled within an operator&#39;s network but limited when
   extending this to home network.  Current definitions of SDP are not
   clear about conveying a local identifier (e.g., a private IP address)
   of the client that is destined to receive media streams after
   successful SDP negotiation.  In this draft we outline the need for
   carrying such information over SDP and discuss a set of possible
   solutions in a scenario with a home network and a operator network
   domain.

I-D Action: draft-george-ipv6-required-02.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title           : IPv6 Support Required for all IP-capable nodes
	Author(s)       : Wesley George
                          Chris Donley
                          Christopher Liljenstolpe
                          Lee Howard
	Filename        : draft-george-ipv6-required-02.txt
	Pages           : 7
	Date            : 2011-06-01

   Given the global lack of available IPv4 space, and limitations in
   IPv4 extension and transition technologies, this document deprecates
   the concept that an IP-capable node MAY support IPv4 _only_, and
   redefines an IP-capable node as one which supports either IPv6 _only_
   or IPv4/IPv6 dual-stack.  This document updates RFC1812, 1122 and
   4084 to reflect the change in requirements.
