TMN Evolution of Reference Configurations for RACE

Objective

The TERRACE project has the objective of defining reference configurations to provide a framework for evolution towards the target IBC-TMN.
The research had the objective of defining reference configurations to provide a framework for evolution towards a target integrated broadband communications (IBC) telecommunication management network (TMN). TMN reference configurations were defined at 3 levels:
Level A (time, network and country independent);
Level B (time and network dependent, country independent);
Level C (time, network and country dependent).
Key issues in the research were:
reference configurations (RC);
national evolution scenarios;
TMN standards;
regulatory issues.

The research has resulted in the following achievements:

The Level A TMN RC has been structured as a template comprising 3 RC key constituents (RCKC) each with 4 subconstituent (RCSC) members;

The following Level B reference case studies have been completed:
synchronous digital hierarchy (SDH);
metropolitan area networks (MAN);
introduction of an asynchronous transfer mode (ATM);
exploration of service management techniques.

Level C TMN reference configurations which have been completed from the series of Level B case studies are:
short term scenario in Ireland;
intermediate scenario (MAN) in Ireland;
intermediate scenario (SDH) in Sweden.
Technical Approach

TMN reference configurations are being defined at three levels: Level A (time, network and country independent), Level B (time and network dependent, country independent) and Level C (time, network and country dependent). The level A TMN reference configuration was defined at an early stage in the project and has recently been reviewed and revised. The Level B TMN reference configurations are being produced as a series of case studies.

The Level C TMN reference configurations definition started with a survey of current network management implementation in a total of 67 networks operated by 14 PTOs plus 19 privately operated networks.

Key Issues
. Reference configurations.
. National evolution scenarios.
. TMN standards.
. Regulatory issues.

Achievements
The Level A TMN-RC has been structured as a template comprising 6 key constituents (RCKCs) each with 4 sub- constituent members (RCSCs).

The following Level B reference case studies have been completed:

. synchronous digital hierarchy (SDH)
. metropolitan area networks (MAN)
. Introduction of ATM based on the results of projects R1014 and R1022
. exploration of service management techniques.

Level C TMN reference configurations which have been completed from the series of Level B case studies are:

. short term scenario in Ireland
. intermediate scenario (MAN) in Ireland
. intermediate scenario (SDH) in Sweden.

Methodologies have been elaborated for TMN reference configuration design and definition of evolution scenarios. A tool (TMN STAX) has been developed to support this methodology.

The TMN reference configuration framework has been captured and documented in CFS M201: TMN Reference Configuration Abstract Framework; and the design activity in CFS M200: TMN Evolution. CFS M210 covers project results on methods for TMN reference configuration design and evolution. Related security aspects have been captured and documented in CFS H210: TMN Security Architecture.

By the end of 1992, the project will have produced 15 deliverables. five contributions to standard bodies, ten papers to workshops and/or conferences; and Issue C of four RACE CFSs. In addition, the project has organised two workshops on key aspects of the TMN evolution (Open Network Provision Impact and TMN Security).

Expected Impact
The partners represented within the project guarantees a comprehensive coverage across Europe. The applicability of the results to the industry and the PTOs is considered obvious.

The project is providing guidelines on the evolution of the management systems from today's situation to the target IBC TMN. TERRACE is therefore expected to continue its impact on the process of standardisation in the field of TMN reference configurations. In addition, it provides a reference technical framework on which a consensus for the management of the target IBC as well as of the key stages of evolution can be achieved.
