Source Recommendation ITU-T J.800.1 was approved on 22 August 2008 by
3、 ITU-T Study Group 9 (2005-2008) under Recommendation ITU-T A.8 procedure. ii Rec. ITU-T J.800.1 (08/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU
4、Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardizat
5、ion Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information techno
6、logy which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Complianc
7、e with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligato
8、ry language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation o
9、f this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the
10、 date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to con

15、DHCP Registry 1 Scope This Recommendation defines the Cable-specific DHCP option codes for DHCPv4 and DHCPv6 including the DHCPv6 Vendor-specific Information Options. The scope of this version of this Recommendation includes: DHCPv4 protocol fields authoritatively assigned by CableLabs that are mand
16、ated for product implementation in eDOCSIS, DOCSIS, IPCable2Home, IPCablecom, and OpenCable specifications. DHCPv6 protocol fields authoritatively assigned by CableLabs that are mandated for product implementation in DOCSIS specifications and in other specifications under development for IPCablecom.
17、 The Cable DHCPv6 options are carried in the DHCPv6 Vendor-specific Information option (option code OPTION_VENDOR_OPTS, Section 22.17 of RFC 3315). The enterprise number for Cable Television Laboratories, Inc. to be used in the DHCPv6 Vendor-specific option, is 4491. The actual product requirements
18、related to the implementation of these DHCP options can be found in relevant ITU-T Recommendations and CableLabs Project specifications. 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 s

34、Values for DHCPv4 Option 43 Several Cable industry Recommendations and specifications mandate implementation of DHCPv4 option 43 by the DHCP client function of consumer premises equipment devices, to convey to the cable operators provisioning system information about the product that can be used to
35、make device and service configuration decisions during the provisioning process. The DHCPv4 Option 43 sub-options code values for all Cable projects for DHCPv4 are listed in Table 1. Also see DHCPv4 Option 43 Syntax Requirements in eDOCSIS. The “used in“ column includes the specifications where thes
