The CADENUS project will propose an integrated solution for the creation, configuration and provisioning of end-user services with QoS guarantees in Premium IP networks. The solution is based on the CADENUS framework, which is a structuring set of core functional blocks at the user - provider interface. It will provide service creation and configuration in a dynamic way through the appropriate linking of user related service components (authorisation, registration, etc.) to network related service components (QoS control, accounting, etc.). For the provisioning of end-user services with QoS guarantees, a number of components are required. Some of them have been developed or are under development in standardisation bodies. Other QoS related issues, will be developed in the project. Also, the project will produce recommendations, architectures, mechanisms and policies concerning service configuration and provisioning for both network operators and service providers.
Objectives:
Objectives: The primary goal of the project is to develop, implement, validate and demonstrate a framework for the configuration and provisioning of end-user services with QoS guarantees in Premium IP networks (eg. for voice over IP).
Sub-Objectives are: To investigate the system-related architectures for implementing Premium IP network transport services to deliver end-user services with QoS. To specify and realise a framework for end-user services having a range of call features and with QoS guarantees. To develop a system implementing the framework which enables the efficient delivery of services by new enterprises and traditional operators. To trial and demonstrate end-user services with QoS guarantees via this framework. To disseminate the results in standards bodies and to the industry in general.
Work description:
The CADENUS project is divided into six coherent workpackages (WPs). WP1, Service Architecture in Premium IP, is responsible for specification of Premium IP networks, development of the service provisioning architecture and specification of the requirements of its components. This includes theoretical studies of the networks, services and systems. WP2, Resource Management and QoS Control in SLA networks, is responsible for the development of a number of the framework components that are required for the provisioning of end-user services with QoS guarantees. These components are yet developed within the standardisation bodies. This includes theoretical studies of the systems, simulations and the actual development. WP3, Service Configuration and Provisioning Framework, is responsible for the actual development of the service configuration and provisioning framework. WP3 will carry out specification of the system requirements, development of framework architecture, framework design, implementation and testing WP4 implements Trials and Demonstrations of the framework components and services implemented via the framework. WP4 is a vehicle for validation of the framework approach in the project. This includes trials planning and evaluation, trials setup, trials support etc. WP5 deals with project management and technical management issues. Within this workpackage, an assessment and evaluation role will also be performed. WP6, Dissemination and Exploitation, co-ordinates external links with other projects (including EURESCOM P906), contributions to standards bodies, links with the relevant fora and project dissemination. It also includes activities related to the exploitation of the technologies developed within the project.
Milestones:
Milestones:
(1) A service configuration and provisioning framework for services with QoS guarantees, which will be developed, implemented, tested and validated in the project.
(2) Recommendations to network providers and service providers on service provisioning in Premium IP networks which include a mix of network technologies like DiffServ/IntServ, MPLS, ATM, IP/ATM etc.
(3) Recommendations to service and network providers on common QoS monitoring and management tools to be used in operation.
(4) A standard way to create and manage Service Level Agreements.
(5) Contributions to standards bodies (IETF, ITU-T, ETSI)
