    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,
