  1. <draft-fessi-nsis-m-nslp-framework-02.txt ><draft-dressler-nsis-metering-nslp-03.txt> Progress Report:Metering NSLP (M-NSLP) 64th IETF meeting, NSIS WG

  2. Overall Status • Two documents • “Framework for Metering NSLP”<draft-fessi-nsis-m-nslp-framework-02.txt > • “NSLP for Metering Configuration Signaling”<draft-dressler-nsis-metering-nslp-03.txt> • Framework document has its first full version • Protocol document is still in progress • Metering NSLP will be presented in the PSAMP WG session • First prototype implementation of the Metering NSLP is running at the University of Tuebingen • Using the GIST implementation from University of Goettingen 2

  3. Summary of Changes in the Drafts since Last Versions (1) • First full version of the framework document • Problem statement of “path-coupled” measurement and metering • Application scenarios • Requirements: • General requirements • Security requirements • Reviews and Comments are very welcome! • Particularly, we are looking for comments on the usage scenarios: • Accounting • QoS Monitoring • Monitoring for Network Security • Which of them do you consider to be { important | useful | irrelevant | nonsense } ? 3

  4. Summary of Changes in the Drafts since Last Versions (2) • M-NSLP protocol document is still progressing • Protocol operation and message processing rules are currently discussed • Metering Specification (MSPEC) is currently being refined • High level state machine • Interaction with GIST 4

  5. MSPEC Issues • MSPEC consists of • <Flow Specification> • Problem: How should the flow specification be related to the MRI? • Discussion somehow related to the packet classifier QSPEC discussion on the mailing list • How can the flow spec be expressed? • In the current version of the M-NSLP, we use the IPFIX information model • <Measured Properties> • e.g. number of bytes, timestamps • <Measured Properties> are expressed using the IPFIX and PSAMP information model. • An extension of the IPFIX information model may be required • <Measurement Configuration Parameters> • e.g. Export Protocol, Export Interval, Collector ID, Aggregation Rules, encryptionRequired, etc. 5

  6. Next Steps • Continue the specification • of the M-NSLP protocol operation • and the MSPEC • Refine state machine • Elaborate security solutions • Continue prototype implementation 6
