STANDARDIZATION ACTIVITIES

Application Profiles

With the concept of Application Profiles AQUILA proves that it is possible to supply legacy non-QoS aware applications with QoS. The solution is based on the assumption that we have a QoS enabled network offering network services and non-QoS aware Internet applications running on a host.

Inter-domain Resource Control (BGRP)

During recent months AQUILA carefully watched the ongoing activities in the IETF regarding QoS signalling. Initial plans to launch a working group in this area started in April 2001. After the 52nd IETF meeting in November 2001 in Salt Lake City, the NSIS (Next Steps In Signalling) working group was established.

From the charter: "This working group will develop the requirements, architecture and protocols for the next IETF steps on signalling QoS."

According to the charter of the NSIS WG, the topic of inter-domain signalling (see also Focal Topics, Multi Domain Aspects) mostly correlates to the work of the AQUILA project. AQUILA therefore prepared two Internet drafts addressed to this WG:

  • draft-aquila-bgrpp-arch
    This draft outlines the architecture of the AQUILA inter-domain signalling based on BGRP. It describes the basic architectural issues as well as the special implementation choices, protocol message content and message processing.

    This draft has been submitted to the IETF and     was announced there as
    <draft-salsano-bgrpp-arch-00.txt>     on May 14, 2002. It expired November 2002.

  • draft-aquila-bgrpp-sim
    This draft presents the mechanisms used for inter-domain resource management and simulation results, which prove the scalability of this approach.

    This draft has been submitted to the IETF and was announced there as
    <draft-nikolouzou-bgrpp-sim-00.txt>     on July 26, 2002. It expires January 2003.

Here is a set of links related to the Inter-domain IP QoS topic.

AQUILA members also actively contribute to the discussion on the NSIS mailing list to promote the AQUILA project's point of view and the submitted drafts.

 

Service Level Specification (SLS)

The TEQUILA project initiated an IETF draft on Service Level Specification (SLS) template definition and Service Level Specification negotiation protocol requirements.

During an AQUILA project meeting extension in Salzburg, Austria, on October 12, 2000, joint activities were discussed and planned in order to gauge interest for the creation of work effort within the IETF on SLS, for a BoF session at the next IETF meeting in San Diego (December 10 - 15, 2000), and for the establishment of an IETF Work Group on these topics.

The Salzburg meeting was one of the first joint meetings of the IST projects AQUILA, CADENUS and TEQUILA, which all work in the area of QoS for the Internet, taking into account different aspects. All projects are supported by the European Commission, Unit INFSO E1 (see IST Concertation)

The BoF session took place at the 49th IETF meeting in San Diego on December 13, 2000, 15:30 - 17:30.
For agenda, minutes, presentations and an e-mail list for SLS interest, please, visit the Service Level Specification Interest Web Page.

Discussions were ongoing - privately organized - during the 51st IETF meeting, London, UK, August 5-10, 2001. Minutes are available.
