Project Overview

The objective of the project is to study, specify, implement and validate a set of service definition and traffic engineering tools to obtain quantitative end-to-end Quality of Service guarantees through careful planning, dimensioning and dynamic control of scaleable and simple qualitative traffic management techniques within the Internet (i.e. diffserv).

The following technical areas will be addressed:

• Specification of static and dynamic, intra- and inter-domain SLSs to support both fixed and nomadic users.
• Protocols and mechanisms for negotiating, monitoring and enforcing SLSs.
• Intra- and inter-domain traffic engineering schemes to ensure that the network can cope with the contracted SLSs, within domains, and in the wider Internet.

Objectives

• Study the issues behind, develop architectures for, and propose algorithms and protocols to enable: negotiation, monitoring and enforcement of Service Level Specifications between service providers and their customers and between peer providers in the Internet.
• Develop a functional model of co-operating components, related algorithms and mechanisms to offer a complete solution for intra-domain traffic engineering to meet contracted SLSs in a cost effective manner.
• Develop a scalable approach, architecture and set of protocols for interdomain SLS negotiation and QoS-based routing to enforce end-to-end quality across the Internet.
• Validate the above through both simulation and/or testbed experimentation.
• Use, enhance and contribute to drafts, specifications and standards of the wider international community, participate in IST consensus activities and disseminate TEQUILA results.
