5. Status of the Schemata Network Monitoring Service XML test request XML tests results • Request Schema: • Ask for results / ask to make test • Schema Requirements Document made • Use DAMED style namese.g. path.delay.oneWay • Send: Char. Time, Subject = node | pathMethodology, Stats • Response Schema: • Interpret results • Includes Observation environment • Much work in progress • Common components • Drafts almost done • 2 (3) proof-of-concept implementations • Implementations using XML-RPC, (Document /Literal ) NMWG GGF10 Berlin March 2004 R.

9. Issues / Needs • Schemata Implementations and Proof of Concept trials very important. • Concern on WS-RF – we don’t want to re-invent • Proposed new Network Measurements Research Group BoF in Hawaii • Link to GHPN-RG work on Network Services • We feel this is positive.
