Cable assigned names and numbers
|Publication Date:||1 August 2008|
This Recommendation is a set of Cable industry registries and namespaces for Names and Numbers. Numerous protocol fields make use of identifiers with well-known names or number values, for example, the IETF DHCP protocol and vendor specific option values, the IETF RADIUS and DIAMETER protocols and associated Cable attributes, etc. To ensure that such quantities have consistent values and interpretations in different implementations, their assignment must be administered by a central authority. For IETF protocols, that role is provided by the Internet Assigned Numbers Authority (IANA). For vendor-specific protocol fields that are defined by Cable industry Recommendations and specifications, or when the use of such protocol identifiers may be common to multiple Cable industry projects and specifications, that role is provided by CableLabs.This Recommendation is a common repository that holds these values.
This Recommendation uses some of the terminology and guidelines of [IETF RFC 2434].
The scope of this version of this Recommendation includes:
• A DHCP registry for protocol fields authoritatively assigned by CableLabs that are in use in eDOCSIS, DOCSIS, IPCable2Home, and IPCablecom, for both IPv4 and DHCPv6.
• An XML registry for XML namespaces for DOCSIS and IPCablecom.
• A DIAMETER registry for IPCablecom.
• A Receive Channel Profile (RCP) registry for CableLabs-defined Standard-RCPs and Vendor-defined Manufacturer-RCPs that are used in DOCSIS 3.0 and beyond to communicate the receiver capabilities of a cable modem.
NOTE - The structure and content of this Recommendation have been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T recommendations has not been applied.
