Foreword This Technical Specification (T
12、S) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction e3 interface based upon CWMP This clause provides an introduction to CWMP protocol, as specified by Broadband Forum, and a high-level descr
13、iption of how the protocol is applicable for the e3 interface specification. CWMP is an HTTP-based protocol, defined by Broadband Forum with TR-069 Technical Report 1, that provides the remote management functionalities for performing provisioning and OAM tasks over managed devices of the Customer P
14、remises Network (CPN). CWMP is specified in ES 203 069 2, which references TR-069 and corresponding data models. In TR-069 1, these devices are generically referenced as Customer Premises Equipment (CPE) devices: a CPE may correspond to the CNG (or Internet Gateway Device, as in TR-069 1) or a CND c
15、onnected to the CNG, i.e. any kind of device behaving as Terminal Equipment. The CWMP protocol defines a set of base communication functionalities and procedures to perform the following remote management tasks on managed devices: configuration management (including software upgrade), fault manageme
16、nt, performance management and security management. CPEs are managed via CWMP by a Remote Management System (RMS), or Auto Configuration Server (ACS) as referenced in TR-069 1. In the manager-agent paradigm, the RMS/ACS provides the CWMP manager function, while the CPE is required to provide the CWM
17、P agent function. The functions provided by a CWMP-based RMS implement the remote management functional entity required for the CNGCF: therefore CWMP is a protocol for implementing the e3 interface. CWMP allows the RMS to manage also CND devices connected to the CNG, in two different ways: a CND may
18、 be proxied by the CNG, i.e. the CND is indirectly managed by the RMS: in this case, the CNG exposes via CWMP the functionalities needed to remotely manage the CND, that is directly controlled by the CNG via other communication protocols on the e3 interface; a CND may be directly managed via CWMP: i
19、n this case, the CND is required to provide the CWMP agent function for direct communication with the RMS; in case the CNG provides the NAPT function, CWMP defines a STUN-based mechanism for the RMS to contact the CND, while the CND is required to provide a STUN-client function. Taking into account
20、the previous two possible applications of CWMP for the e3 interface, such a CWMP-manager entity provides a generic Customer Premises Network Configuration Function (CPNCF). ETSI ETSI TS 183 065 V3.1.1 (2011-07)51 Scope The present document provides the ETSI TISPAN endorsement of ES 203 069 2, which
21、references Broadband Forum TR-069 1 “CPE WAN Management Protocol“ (CWMP). The endorsement is in line with the requirements of TISPAN NGN for the specification of the e3 interface. 2 References References are either specific (identified by date of publication and/or edition number or version number)
22、or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.
