IP over Cable Data Network (ipcdn) Charter

Description of Working Group
The goal of the IPCDN WG is to define how the Internet Protocol (IP) is
to be supported on a Cable Television (CATV) Data Network. The working
group will prepare a framework and requirements document describing a
typical CATV infrastructure and how an IP based network might be
architected to utilize this infrastructure. It will also address the
service interface between IP and the CATV Data Network. The
architecture document will discuss the technical details related to the
differences between symmetric and asymmetric CATV Data Networks. A
terms of reference document will also be published.
Currently, there are no standards available for supporting IP over a
CATV Data Network. The IEEE 802.14 WG is chartered to specify the
physical layer and data link layer protocols for the CATV Data Network.
However, this does not address the issue of mapping higher level
protocols onto the hybrid fiber coax (HFC) access networks. The IPCDN
WG will define a specification of how IP is mapped onto HFC access
networks. Both IPv4 and IPv6 will be addressed, although in separate
documents. The following topics will be discussed:
multicast, broadcast, address mapping and resolution (for IPv4) and
neighbor discovery (for IPv6).
The IPCDN WG will also address issues related to network management,
especially as they concern HFC access networks. It is expected that
other services (i.e. DHCP, RSVP, IPSEC, etc.) will operate unmodified.
Also, depending on the capabilities provided by cable data network
service, specific mappings of RSVP service classes to lower layer
services might be desirable. If additional capabilities become
necessary, these will be directed to the appropriate group.
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.
The WG is chartered to deliver the following set of documents:
- informational RFCs covering the framework, architecture,
requirements and terms of reference for Cable Data Networks.
- an IPv4-over-HFC access network document covering the mapping
of IP over RF channels, encapsulation and framing of IPv4 packets,
IP to modem and/or PC address resolution, multicast, and broadcast.
- an IPv6-over-HFC access network document covering the mapping
of IP over RF channels , encapsulation and framing of IPv6 packets,
IP to modem and/or PC address resolution, neighbor discovery,
multicast, and broadcast.
- a media-specific mib for managing HFC spectrum.
- a mib for managing cable data network service including
management of IP over cable data network.
