Project organisation

The project is structured around four Work Packages:

WP0, Project Management and Co-ordination of External Liaison, is concerned with the administrative and technical management of the project, including liaison with other projects and co-ordination of dissemination and standardisation.

WP1, Specification of Functional Architecture, Algorithms and Protocols, is responsible for defining a business model and a generic, multi-domain, multi-service IP QoS functional architecture for inter-domain QoS delivery. The main output will be the specification of algorithms and protocols for negotiation and establishment of inter-domain SLSs, inter-domain TE and routing, including the required interactions with intra-domain TE and route computation capabilities to achieve inter-domain QoS delivery.

WP2, System Design and Implementation, will enhance experimental routers and simulators to support the inter-domain QoS requirements of the project. Based on the specifications from WP1, WP2 will design and implement the specified algorithms and protocols, as both testbed prototypes and simulation tools/models. WP2 will deliver prototypes and simulators to WP3 in an incremental way to allow experimentation activities to take place.

WP3, Integration, Validation and Experimentation, is responsible for setting-up the required experimentation infrastructure and for performing validation and performance evaluation activities on the prototypes and simulators developed by WP2. The testbed experiments are focussed on proof-of-concept validation, while the simulation experiments aim at assessing the performance and scalability of the project’s inter-domain solutions.
