Mr Yoichi Maeda, Chairman, ITU-T Study Group 15, addressing the WTSA-12 Plenary
ITU-T Study Group 15 Chairman, Yoichi Maeda, today presented a compromise proposal developed by several delegations which cleared the way for approval of Recommendation ITU-T G.9980. The standard defines requirements for service providers’ remote management of networked devices in customers’ homes.
The compromise was achieved after including a statement in the scope of the Recommendation which reminds implementers and users to comply with all applicable national and regional laws, regulations and policies.
Recommendation ITU-T G.9980 Remote management of CPE over broadband networks – CPE WAN Management Protocol (CWMP) is based on a Broadband Forum protocol commonly referred to as TR-069. The protocol may be used to manage various types of customer premises equipment (CPE), including stand-alone routers and LAN-side client devices. Functionalities include:
- auto-configuration and dynamic service provisioning;
- software/firmware image management;
- status and performance monitoring;
Though it depends on IP-layer connectivity, CWMP is agnostic to the specific access medium utilized by the service provider.
Recommendation ITU-T G.9980 will be made available free of charge at http://itu.int/ITU-T/recommendations/.
Participants at WTSA-12 have approved key standards (ITU-T Recommendations) on a technology for multiprotocol label switching – transport profile (MPLS-TP) required by telecoms operators to increase network efficiency while also reducing capex and opex costs.
Recommendation ITU-T G.8113.1, “Operations, Administration and Maintenance mechanism for MPLS-TP in Packet Transport Network (PTN),” provides an Ethernet-based protocol for operations, administration and management (OAM) in Transport Networks. MPLS can carry packets of different types, allowing telecom operators to offer private connections as well as IP services. Many network operators expect MPLS-TP to work under the same principles as longstanding ITU transport network technologies like SDH and OTN. MPLS-TP provides network operators with a reliable packet-based technology, the operation of which aligns with current organizational processes and large-scale work procedures. Its deployment may reduce the need for layer 3 routing in an operator’s network.
Recommendation ITU-T G.8113.2/Y.1372.2, “Operations, administration and maintenance mechanisms for MPLS-TP networks using the tools defined for MPLS,” is an extension to the IETF’s MPLS protocol and is developed in cooperation with the Internet Engineering Task Force (IETF). It is a Transport Profile of MPLS and can be used for OAM in Transport Networks.
The IETF is soon expected to provide an ACh codepoint for the Ethernet-based OAM protocols.
Also approved during the first plenary of the Assembly were Recommendation ITU-T D.195 (“Time-scale for settlement of accounts for international telecommunication services”), ITU-T Y.2770 (“Requirements for Deep Packet Inspection in Next Generation Networks”) (with modification) and ITU-T G.9901 (“Narrowband OFDM Power Line Communication Transceivers – Power spectral density (PSD) specification”).
