  1. Functional design of Domain Tool UCL e2e monitoring workshop May 15th, 2003 Victor Reijs victor.reijs@heanet.ie

  2. Outline • Co-operation environment... • Environment of Domain Tool... • Functions... • Interfaces... • Issues...

  3. Co-operation environment • I2: 4 years ago talk on e2e problem: • NLM-HEAnet and VidiNet: Chariot • TF-NGN: • PERT • Performance infrastructure • NIMI • GGF/OGSA • E2E piPEs • Monalisa, others?

  4. Outline • Co-operation environment... • Environment of Domain Tool... • Functions... • Interfaces... • Issues...

  5. Environment of Domain Tool • man • machine • developer • administrator User representation Access interface Domain Tool... Inter-domain interface Other Domain Tools MP interface Un-Instrumented networks Instrumented networks MP

  6. Domain Tool block Access interface Inter-domain interface Domain specific block... API interface Analyses+ aggregation Driver interface MP driver MPspecific block Domain Tool MP interface

  7. Domain Specific block Access interface Inter-domain interface Communication AAA Scheduler Pathfinder Aggregation DBMS Administration Data analyses Domain specific API interface

  8. Outline • Co-operation environment... • Environment of Domain Tool... • Functions... • Interfaces... • Issues...

  9. Functions • Administration… • Communication… • AAA • Scheduler… • Pathfinder... • DBMS… • Aggregation… • Data Analysis…

  10. Administration • knows what Domain Tool can do • knows about the feature set of connected MP’s • keeps track of test functionalities available [NMWG] • keeps track of other Domain Tools (JINI?) • keeps track of users and AAA • keeps track of aggregation functions • keeps domain policies

  11. Communication • does communication to other Domain Tools • schedules communication paths inside Domain Tool • [NIMI]

  12. Scheduler • accepts information requests • asks for path (using Pathfinder) • does resource management of Domain Tool and MP’s • determines if test is needed (could be in Database) • uses AAA towards MP specific block • does test management (start, stop, abort, etc.) • provides database exceptions/error information • [E2E piPEs]

  13. Pathfinder • determines MP’s in the e2e path • determines the IP path • for own domain: finds MP’s on path • determines neighbor Domain Tool • un-instrumented domain exists

  14. DataBase Management System • has (distributed) Domain Database • knows if MP’s have Local Database(s) • uses AAA • determines if data is available [Test Arbiter] • [OGSA]

  15. Aggregation • has domain specific aggregation functions... • aggregates test results for domain • provides aggregated results • provides aggregated exceptions/error information

  16. Aggregation functions • Statistical functions: • mean, percentile, standard deviation, etc. [NMWG] • adding averages, concatenation, etc.

  17. Data Analyses • knows how to analyze the test results of MP’s • uses MP specific aggregation functions... • anonymizes data • provides MP results • provides MP exceptions/error information • [test engine, E2E piPEs]?

  18. Outline • Co-operation environment... • Environment of Domain Tool... • Functions... • Interfaces... • Issues...

  19. Interfaces • Access interface (XML, SOAP) • user (man or machine) • domain administrator • MP developer • Inter-domain interface (XML) • Driver interface • MP interface [PMP, E2EpiPEs?] (proprietary) • API interface (XML?) • data analyses • aggregation functions

  20. Outline • Co-operation environment... • Environment of Domain Tool... • Functions... • Interfaces... • Issues...

  21. Issues • Chaining and/or referral (resilience)? • Data and AAA • 3 levels: multi-domain, domain, MP • Aggregation, Data Analyses, Scheduler • Agree common/defined naming • Work together!
