This is the draft version of the meeting notes for the March 3rd, 2009 meeting of NML-WG second session at OGF 25, 14:00 - 15:30 CET. Please give comments and corrections. About 20 attendees have been present (please check) NML-WG Schema Definition Document ================================= Curently the following structure has been proposed and the persons giving/collecting input have been proposed - Introduction <- Jeroen van der Ham & Martin Swany - Schema <- Jeroen & Martin - Identifiers <- Lars Fischer - non-normative use examples <- Fred Dijkstra The original supposed chapter "Syntax" will be handled in a different document Document should be in Latex, so that no real editor is needed First draft to be ready at OGF26 Identifier discussion (urn:ogf:network:...) =========================================== Email to Joel Repogle by Richard Hughes-Jones & Jeroen for registration Joel will contact IANA for urn:ogf:network naming scheme Issues tracker (responsible Freek) ================================== - NSI Issues (John Vollbrecht & Freek) Slides of meeting will be put online by Martin & Jeroen ======================================================= Minutes of session will be provided by Freek and Ralph Niederberger =================================================================== Latex SVN repository (responsible Freek) ======================================== Freek made a short proposal =========================== Use cases are high level Freek would like to have a repository of use cases Describe small use cases e.g. a named link having a different name than its interfaces connected to the link http://forge.gridforum.org/sf/wiki/do/viewPage/projects.nml-wg/wiki/IssuesTr... Presentation: Network Services Interfaces by John Vollbrecht ============================================================ Status of NSI Generating a use case document & architecture document Concerning Architecture WG bi-weekly VC call since January A lot of issues found. See presentation for details Discussion led to set of "Issues documents" which provide info about thouhgts and decisions See: http://forge.gridforum.org/sf/docman/do/listDocuments/projects.nsi-wg/docman... NSi & NML collaboration in naming conventions is needed and desirable Many similarities and work items, so: Suggestion that NML and NSI have formal collaboration NSI-WG is working on Connection Oriented Network Service interface (Co-NSI) currently Requestor agent communicates with CO-NS agent via CO-NSI. Network Service Data Planes are connected via Link Connection Segments in a Multi-Domain Network Service. Data connections cross multiple Network Services Next Steps: Work on model of Network Service Work in user cases and how to describe them Create Architecture document by OGF268 Define required collaborations: NML, Security, Job Scheduling, others? Suggestions/Questions by audience: Which kind of security? What about Accounting and Authorization of Requesting ressources? Answers: Yes, these are also things to think about. How should collaboration be organized? - Send requests to NML or - direct discussion (e.g. live issue tracker) -> Wiki should be used Freek announces a "Terminology table" ========================================== This document is available via Gridforge. (only informational, that different standards use different terminologies and for checking, which terminology to use when talking to each other) best regards Ralph -- *************************************************** Ralph Niederberger Juelich Supercomputing Centre Institute for Advanced Simulation Phone: +49 2461 61-4772 Fax: +49 2461 61-6656 E-Mail: r.niederberger@fz-juelich.de WWW: http://www.fz-juelich.de/jsc/ JSC is the coordinator of the John von Neumann Institute for Computing and member of the Gauss Centre for Supercomputing *************************************************** Forschungszentrum Jülich GmbH 52425 Jülich Sitz der Gesellschaft: Jülich Eingetragen im Handelsregister des Amtsgerichts Düren Nr.
