Objetivo

The main objectives of the project are to:

. Define QoS verification methodologies for the IBC environment.
. Define mapping models, supporting relations between QoS and performance, applicable in the framework of the verification methodologies.
. Develop experimental tools for QoS verification, exploiting the mapping models.
The main objectives of the project are to:
define quality of service (QoS) verification methodologies for the integrated broadband communications (IBC) environment;
define mapping models, supporting relations between QoS and performance, applicable in the framework of the verification methodologies;
develop experimental tools for QoS verification, exploiting the mapping models.
Achievements of the project are:
definition of an overall QoS model QOSMIC Cube of Service Management Methodologies, combining the service life cycle, represented by the Timeline Model, and the associated customer/provider aspects;
clarification of QoS performance relationships and terminology;
completion of experimental tool Prototype 1, implementing the file transfer case study. (This prototype has been demonstrated at Telecom 1991 in Geneva and at the Telecommunication Management Network (TMN) Conference 1991);
active contribution to the work in sub-technical group (STG) 1.4 (Quality of Service and network performance (NP));
leadership in the production of common functional specification (CFS) D510 and H531, contribution to standard;
presentation of the Timeline Model and clarification on QoS and performance terms to European Telecommunications Standards Institute (ETSI).
Technical Approach

The approach taken divides the work into two complementary parts:

Analytical part
. Definition of an overall QoS model, taking into account the life cycle of a service and both user and provider views.
. Definition of verification methodologies, applicable in the framework of the QoS model, and QoS performance mapping models based on the decomposition of end-to-end services into elements.
. Application of mapping models to selected case studies: file transfer, HDTV, video conference.

Practical developments
. Development of two experimental tool prototypes, exploiting mapping formulas of the analytical work, to derive QoS at both ATM and application levels. Prototype 1 runs in an ATM network simulation environment. Prototype 2 adds a physical sub-system to Prototype 1, which connects to the user-network interface (UNI) thus allowing live evaluation of QoS, first in demonstrator environments and, later on, in IBC field trials.

Key Issues

. Clear definition of Quality of Service.
. Identification of relevant performance parameters.
. Practical validation of models and tools.

Achievements
. Definition of an overall QoS model QOSMIC Cube of Service Management Methodologies, combining the service life-cycle, represented by the Timeline Model, and the associated customer/provider aspects.
. Clarification of QoS performance relationships and terminology.
. Completion of experimental tool Prototype 1, implementing the file transfer case study. This prototype has been demonstrated at Telecom '91 in Geneva and at the TMN Conference '91.
. Active contribution to the work in STG 1.4 'Quality of Service and NP'. Leadership in the production of CFSs D510 and H531, contribution to standard.
. The Timeline Model and clarification on QoS and performance terms have been presented to ETSI in 1991.
. Dissemination of results within project member companies (presentations, seminars, communication of papers) and in RACE (Deliverables sent to several projects upon request, presentations at RCMs).

Expected Impact
. On service providers and customers: a framework for comprehensive handling of QoS verification issues in planning and operational phases.
. On verification tool providers: a basis for the development of QoS and performance verification tools adapted to the ATM technology.
. On standards related with QoS: enhancements to the definitions, scopes and correlations of QoS terminology and verification functions.
