The IETF IPCDN Working Group develops and standardizes SNMP MIBs for IP-capable data-over-cable systems, for example cable modems and associated cable-data equipment in a Headend. These MIBs cover not only cable data interfaces, but also management of cable-data equipment and systems.
The WG is also a forum for discussion of 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 work is identified, such items MAY be added that to the WG's charter, subject to normal IETF processes. Standardisation of MIBs for the EuroModem cable modem is within the scope of the IPCDN Working Group. Harmonisation of EuroModem MIBs and DOCSIS MIBs is desirable and will be examined by the IPCDN WG.
The IPCDN WG will also keep informed on what other groups in the industry are doing as it relates to the work of this working group.
Related groups:
The IEEE 802.14 WG was chartered to specify the physical layer and data link layer protocols for the CATV Data Network. The IEEE has discontinued the IEEE 802.14 effort, so that group no longer exists.
DOCSIS has completed its 1.0 versions of Data over Cable standards and is in the process of refining these standards to add additional functionality and to repair any flaws discovered in operational use. The IPCDN WG will update the documents produced which track the 1.0 versions accordingly. These include the RF Interface MIB and the Cable Device MIB. In addition, the operational and management issues of multicast over a Cable Data Network will be addressed.
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.

IPCDN WG Minutes, August 9, 2001
The WG meeting was very short as there was only one I-D author present and less than a dozen attendees. Due to the lack of I-D authors present, the WG chair could only report the current status of the WG I-Ds (see slides) and was unable to agree timescales for completion of outstanding I-Ds with the exception of the DVB MIBs.
The WG chair explained to the WG that due to various factors, the slow adoption of DVB Cable return channel meant that is would not be possible to produce standards track RFCs for the DVB MIBs as there were not enough implementors. The AD (Thomas Narten) suggested that it may be possible to publish the DVB I-Ds as informational with a caveat in them stating they did not complete the IETF process and should anyone wish to implement them, the MIBs should be resubmitted to the IETF and the work finished.
