Traffic Engineering for Quality of Service in the Internet, at Large Scale

Objective

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 (QoS) 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:
(a) Specification of static and dynamic, intra- and inter-domain SLSs (Service Level Specification) to support both fixed and nomadic users.
(b) Protocols and mechanisms for negotiating, monitoring and enforcing SLSs.
(c) Intra- and inter-domain traffic engineering schemes to ensure that the network can cope with the contracted SLSs - within domains, and in the Internet at large. All specified functionality will be validated through simulation, prototype development and network experiments.

Objectives:
The project has five key objectives:
(1) 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.
(2) 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.
(3) 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.
(4) Validate the above through both simulation and/or testbed experimentation.
(5) Use, enhance and contribute to drafts, specifications and standards of the wider international community, participate in IST consensus activities and disseminate TEQUILA results.

Work description:
The overall work in the TEQUILA project is split over 3 workpackages, and follows a phased approach: a theoretical phase followed by a refinement phase, then an experimentation and dissemination phase.

Milestones:
The expected results include:
- A validated framework for the provisioning/definition of end-to-end QoS through the Internet
- Models for access and inter-domain SLSs.
- Specification and evaluation of intra- and interdomain SLS negotiation protocols
- A validated framework for end-to-end QoS monitoring
- Validated intra- and inter-domain traffic engineering methods, tools and algorithms deployable in Diffserv capable IP networks
