ITU-T G.9980 (11/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communicati
9、on technologies (ICTs). The ITU 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 Worl
10、d Telecommunication Standardization 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
11、some areas of information technology 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 recogn
12、ized operating agency. Compliance 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 wo
13、rds “shall“ or some other obligatory 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 tha

18、ec. ITU-T G.9980 (11/2012) Introduction The basis of this Recommendation is the Broadband Forum CPE WAN management protocol (CWMP), commonly referred to as TR-069. The protocol is intended for communication between a CPE and an auto-configuration server (ACS). The CPE WAN management protocol defines
19、 a mechanism that encompasses secure auto-configuration of a CPE, and also incorporates other CPE management functions into a common framework. TR-069 specifies the generic requirements of the management protocol, and methods that can be applied to any TR-069 CPE. Other Broadband Forum technical rep
20、orts (TRs) specify the managed objects, or data models, for specific types of devices or services. The protocol may be used to manage various types of CPE, including stand-alone routers and LAN-side client devices. It is agnostic to the specific access medium utilized by the service provider, althou
21、gh it does depend on IP-layer connectivity having first been established by the device. Rec. ITU-T G.9980 (11/2012) 1 Recommendation ITU-T G.9980 Remote management of customer premises equipment over broadband networks Customer premises equipment WAN management protocol 1 Scope This Recommendation d
22、efines the requirements for the remote management of networked devices by a service provider in a consumers home. It provides an overview of, and the necessary normative references to, a family of technical specifications (see Figure 1). It describes how the various technical specifications in this
23、family are related. CPE such as G-PON ONUs may be partially managed by OMCI, as specified in b-ITU-T G.988. b-ITU-T G.988 defines options for shared management of such devices. These options, and the OMCI management of CPE, are outside the scope of this Recommendation. The protocol is intended to pr
24、ovide flexibility in the connectivity model. The protocol allows both CPE and ACS initiated connection establishment, avoiding the need for a persistent connection to be maintained between each CPE and an ACS. The functional interactions between the ACS and CPE should be independent of which end ini
25、tiated the establishment of the connection. In particular, even where ACS initiated connectivity is not supported, all ACS initiated transactions should be able to take place over a connection initiated by the CPE. The protocol allows one or more ACSs to serve a population of CPE. Each CPE can only
26、be associated with one ACS, while each ACS may be associated with one or more service providers. However, a single physical device may present more than one logical CPE device, each of which may be associated with a different ACS. The protocol provides mechanisms for a CPE to discover the appropriat
27、e ACS for a given service provider. The protocol provides mechanisms to allow an ACS to securely identify a CPE and associate it with a user/customer. Processes to support such association support models that incorporate user interaction as well as those that are fully automatic. The protocol allows
28、 an ACS to control and monitor various parameters associated with a CPE. The mechanisms provided to access these parameters are designed with the following premises. Different CPE may have differing capability levels, implementing different subsets of optional functionality. Additionally, an ACS may
29、 manage a range of different device types delivering a range of different services. As a result, an ACS must be able to discover the capabilities of a particular CPE. An ACS must be able to control and monitor the current configuration of a CPE. Other entities besides an ACS may be able to control s
30、ome parameters of a CPEs configuration (e.g., via LAN-side auto-configuration). As a result, the protocol must allow an ACS to account for external changes to a CPEs configuration. The ACS should also be able to control which configuration parameters can be controlled via means other than by the ACS
31、. The protocol should allow vendor-specific parameters to be defined and accessed. 2 Rec. ITU-T G.9980 (11/2012) The protocol is intended to minimize implementation complexity, while providing flexibility in trading off complexity vs. functionality. The protocol incorporates a number of optional com
32、ponents that come into play only if specific functionality is required. The protocol incorporates existing standards where appropriate, allowing leverage of off-the-shelf implementations. The protocol is agnostic to the underlying access network. The protocol is also extensible. It includes mechanis
33、ms to support future extensions to the standard, as well as explicit mechanisms for vendor-specific extensions. Figure 1 CPE WAN management protocol and its related technical specifications Any protocol describing remote configuration or software-/firmware modification of CPEs must provide the capab
34、ilities to comply with all applicable national and regional laws, regulations and policies. The implementation of mechanisms to ensure the explicit endorsement of the customer by means of opt-in permissions before remotely initiating any procedures on the CPE may be required by some specific nationa
35、l and regional laws, regulations and policies. Implementers and users of the described CWMP shall comply with all applicable national and regional laws, regulations and policies. Implementers and users of all ITU-T Recommendations, including ITU-T G.9980 and the underlying techniques, shall comply w
