Internet Design for SLS Delivery
"From Service Level Specification to Per Hop Behaviour"
|The IST-TEQUILA project organised a workshop
on Quality of Service in IP networks and Internet Design for SLS delivery.
This workshop was held in Amsterdam on 25-26 January 2001.
Presentations, Pictures and Attendees
The presentations are now available on the Web through the workshop program web page. A list of the workshop attendees is also available here.Take a look at the workshop pictures page, by Michael Smirnov (GMD-FOKUS / CADENUS Project). Some more pictures by David Griffin (UCL / TEQUILA).
The workshop focuses on two (related) topics:
Background on the TEQUILA project
The European project TEQUILA (IST-1999-11253) stands for Traffic Engineering for Quality of Service in the Internet, at Large Scale. TEQUILA's main objective is to study, specify, implement and validate service definition and Traffic Engineering tools for the Internet. The TEQUILA system should provide both quantitative and qualitative service guarantees through planning, dimensioning and dynamic control of traffic management techniques based on DiffServ. The project addresses the following technical areas: (a) Specification of static and dynamic, intra- and inter-domain SLSs (Service Level Specification). (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.

SLS related standardisation efforts in the IETF
Members of the TEQUILA project introduced a first Internet Draft ("SLS - contents, parameters and semantics") on the SLS topic in June 2000. A second version of this draft and a proposal for a "Service Level Usage and Specification Framework " has been produced. These drafts together with two other proposals of AT&T and the IST-AQUILA project are currently discussed on a public mailing list: firstname.lastname@example.org .To subscribe to the list send an email to email@example.com with the sentence: subscribe firstname.lastname@example.org in the body and nothing in the subject line.
