Internal WG Review: Recharter of IP over Cable Data Network (ipcdn)
A new charter for the IP over Cable Data Network (ipcdn) Working Group in the
Operations and Management Area of the IETF is being considered.
The draft charter is provided below for your review and comment.
Review time is one week.
The IETF Secretariat.

IESG, IAB
This WG currently exists in the INT Area. But all they do is
work on MIB documents. Basically it means that I interact with
them much more than any of the INT ADs (which is indeed
logical if they just work on MIBs).
So Thomas, Margaret and I have discussed with the WG chairs
to move the WG to OPS area and I will then be primary AD.
WG chairs agree with that.
At the same time, the WG has a whole set of new MIB docs
they want to work on (in fact they are already working on
them). So the charter lists those new MIB documents and
has new milestones for them. The milestones have been
kind of aligned with Cablelabs Certifaction Waves, so that
is hoped to help motivate the WG pariticpants to finish
by some specific date. Let us hope that that will indeed work.
Below is the proposed re-charter text. There is quite extensive
background info included, which may seem superfluous, but I think
it does help readers of the charter to understand how this all
relates to other work in the cable industry.
Thanks,
Bert

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 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 MIB work, 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, PacketCable and CableHome
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 STD.
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.
In its CableHome project, CableLabs has produced one generation
of interface specifications for extending manageability for
customer care to the residential gateway or home router device
connected to the Internet through a DOCSIS-compliant cable modem
(http://www.cablelabs.com/projects/cablehome/).
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.
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.
CableHome 1.0 is a set of specifications for residential
gateway or home router functionality standardizing methods
for implementing address acquisition, device configuration
and management, network address translation, event reporting,
remote connectivity diagnostics, secure software download,
firewall policy file download, firewall monitoring,
management parameter access control and other residential
gateway functionality. By standardizing these features,
CableHome 1.0 specifications enable cable operators to
deliver high-value, managed broadband services to their
high-speed data service subscribers, through a DOCSIS cable
modem.
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,
-- CableHome
- publish MIB documents for:
- managing attributes of a residential gateway or
home router device,
- managing private address-to-public address mappings
for a residential gateway or home router device,
- managing the address lease acquistion client and the
address lease server functionality of a residential
gateway or home router device,
- managing diagnostic utilities used to remotely test
the connectivity between a residential gateway and
privately-addressed LAN hosts,
- managing firewall attributes, monitoring firewall
attacks, and managing security certificates in a
residential gateway or home router device,
- managing QoS configuration in a residential
gateway or home router device.
