The charter of the IP over Cable Data Network (ipcdn) working group in the Operations and Management Area of the IETF has been updated. For additional information, please contact the Area Directors or the working group Chairs. +++ IP over Cable Data Network (ipcdn) ================================== Current Status: Active Working Group Chair(s): Richard Woundy <Richard_Woundy@cable.comcast.com> Jean-Francois Mule <jf.mule@cablelabs.com> Operations and Management Area Director(s): Bert Wijnen <bwijnen@lucent.com> David Kessens <david.kessens@nokia.com> Operations and Management Area Advisor: Bert Wijnen <bwijnen@lucent.com> Mailing Lists: General Discussion: ipcdn@ietf.org To Subscribe: http://www.ietf.org/mailman/listinfo/ipcdn Archive: http://www.ietf.org/mail-archive/web/ipcdn/index.html Description of Working Group: The IETF IPCDN Working Group develops and standardizes MIBs for IP-capable data-over-cable systems, for example cable modems, multimedia terminal adapters and associated cable-data equipment in a cable headend. These MIBs cover not only cable data interfaces, but also management of cable-data equipment and systems. The WG mailing list may be used to discuss Internet-related issues in data-over-cable equipment and systems. In the event of a particular new Internet technology issue arising in the cable-data context, the WG will identify whether that is best handled within the IETF or is best handled by another standards body. In the event that new IETF MIB work is requested, the WG chairs can discuss additional WG work items with the AD. Such additions will have to go through normal re-charter process. If non-MIB work gets identified, such items are not normal work items for this IPCDN-MIB WG and must go through normal IETF new WG chartering process. Standardization of MIBs for DOCSIS and PacketCable systems are explicitly within the scope of the IPCDN Working Group. The IPCDN WG will also keep informed on what other groups in the industry are doing as it relates to the efforts of this working group. The WG will align its specifications with IPv6 and SNMP Standards. Related groups: CableLabs (http://www.cablelabs.com/) is structured into projects. In its Cable Modem DOCSIS project, CableLabs has produced three generations of data over cable specifications: DOCSIS 1.0, DOCSIS 1.1, and DOCSIS 2.0. In its PacketCable project, CableLabs has produced one generation of interface specifications for delivering real-time multimedia services over DOCSIS (http://www.packetcable.com/specifications/). Internationally, IPCablecom is the global name associated with the extensions & global standardization of PacketCable in ETSI & ITU-T SG9. DOCSIS 1.0 includes specifications for a bidirectional data-over-cable interface (RFI, or Radio Frequency Interface) and a data privacy service (BPI, or Baseline Privacy Interface). The key devices in a DOCSIS network are the Cable Modem (CM, the device at the subscriber premise) and the Cable Modem Termination System (CMTS, the device at the cable headend). For DOCSIS 1.0 systems, the IPCDN WG has published the Cable Device MIB (RFC 2669), the RF Interface MIB (RFC 2670), and the Baseline Privacy MIB (RFC 3083). DOCSIS 1.1 extends the DOCSIS 1.0 specifications to support better quality of service parameters (RFIv1.1), to enable operation in European cable networks (EuroDOCSIS), and to authenticate modems and firmware images (BPI+). The IPCDN WG will update the Cable Device and Radio Frequency MIBs for DOCSIS 1.1, and repair flaws discovered in operational use. Other IPCDN WG documents will address the operational and management issues for new DOCSIS 1.1 functional components (e.g. BPI+), for subscriber device management, and for uniform event notification. The IPCDN WG has also published the DOCSIS Subscriber Management MIB (RFC4036) for DOCSIS 1.1 and 2.0 systems. DOCSIS 2.0 enhances the DOCSIS 1.1 specifications at the physical layer, in particular to support two new physical layer encodings: S-CDMA and A-TDMA. The IPCDN WG will update the Radio Frequency MIB for DOCSIS 2.0. PacketCable 1.0 is built on top of the DOCSIS 1.1 cable modem infrastructure and it includes a suite of interface specifications covering multimedia terminal adapter (MTA) device provisioning, voice over IP session signaling, QoS signaling based on IETF standards. The key systems in a PacketCable network are the multimedia terminal adapter (MTA), a Call Management Server (CMS), a PacketCable-compliant DOCSIS 1.1 CMTS, Media Gateway Controllers, Media Gateways along with back-office systems. In ITU-T SG-9 and ETSI AT, IPCableCom has standardized PacketCable to create a set of international standards. Work items: The IPCDN WG will address issues related to network management, especially as they concern HFC access networks. It is expected that other services (i.e. RSVP, IPSEC, etc.) will operate mostly unmodified. The specific work items include -- DOCSIS, - publish MIB documents for: - subscriber device management on a DOCSIS 1.1 CMTS, - managing the quality of service parameters for a DOCSIS 1.1 device, - managing the Baseline Privacy Plus system for a DOCSIS 1.1 device, - uniform event notification on a DOCSIS 1.1 device, - revise MIB documents for: - DOCSIS 1.0 RF Interface MIB to support EuroDOCSIS parameters and DOCSIS 2.0 physical layer management, - the DOCSIS 1.0 Cable Device MIBs to address SNMPv3 and IPv6 compliance and interoperability issues, -- IPCablecom & PacketCable - publish MIB documents for: - managing the device parameters of PacketCable/IPCableCom MTA devices, - managing the signaling parameters of PacketCable/IPCableCom MTA devices, - managing events for PacketCable/IPCablecom systems, Goals and Milestones: Done Post final I-D on Baseline Privacy MIB; Last call Done Post I-Ds revising RF and CM MIBs to support DOCSIS1.1 and for compliance with SNMPv3 and IPv6 Done Submit Baseline Privacy MIB to IESG for publication as a Standards Track RFC Done Submit DOCSIS Subscriber Management MIB to IESG for consideration as a Standards Track RFC Done Submit DOCSIS 1.1 QoS MIB to IESG for consideration as a Standards Track RFC Done Submit DOCSIS BPI+ MIB to IESG for consideration as a Standards Track RFC Done Submit DOCSIS Event Notification MIB to IESG for consideration as a Standards Track RFC Oct 05 Submit updated DOCSIS RF MIB to IESG for consideration as a Standards Track RFC (Proposed Standard) Oct 05 Submit updated DOCSIS Cable Device MIB to IESG for consideration as a Standards Track RFC Oct 05 Submit PacketCable/IPCableCom MTA device MIB to IESG for consideration as a Standards Track RFC Oct 05 Submit PacketCable/IPCableCom MTA signaling MIB to IESG for consideration as a Standards Track RFC Dec 05 Submit PacketCable/IPCableCom MTA event MIB to IESG for consideration as a Standards Track RFC Jan 06 Re-evaluate charter and milestones or conclude wg. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
