Re: [nmrg] RE: Proposed IETF Working Group: sming
For your information, several years ago standards bodies involved in
telecom management also recognized the need for the "definition of a
transport-independent information information model so as to allow a
variety of implementation-specific technologies to be derived from a
single definition." This need was driven by advances in technologies
applicable to telecom management, in fact to the management of networks
of any description, and market pressures to take advantage of these
advances.
More specifically, ITU-T Study Group 4, which is responsible for the
Telecommunication Management Network (TMN) framework, information
models, and protocols, recently approved a revised TMN interface
specification methodology in Recommendation M.3020 based on the
following principles:
- requirements need to be understandable to telecom management experts
and yet provide sufficient detail to drive information modeling
- information model details must be traceable to requirement details
- information definitions must be defined independent of deployment (ie
implementation) technology
- industrial strength graphical methods and tools should be used, with
an initial focus on OMG-approved Unified Modeling Language (UML)
notations, including use case, class structure, sequence, collaboration,
activity, and implementation diagrams as well as state charts
- support for CMIP and CORBA environments should be provided initially
This work was supported by related regional and national standards
bodies, such as ETSI and T1, and built upon related work in the
TeleManagement Forum.
The role of M.3020 in TMN was described during the TMN SNMP BOF held at
the IETF March meeting in Adelaide and related information from that
BOF, including a copy of M.3020-2000, is available via ftp as follows:

Any comments on the above are of course welcome.
