  xtgt
• 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

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 ?

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

5
MSPEC Issues

• MSPEC consists of
• ltFlow Specificationgt
• 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
• ltMeasured Propertiesgt
• e.g. number of bytes, timestamps
• ltMeasured Propertiesgt are expressed using the
  IPFIX and PSAMP information model.
• An extension of the IPFIX information model may
  be required
• ltMeasurement Configuration Parametersgt
• e.g. Export Protocol, Export Interval, Collector
  ID, Aggregation Rules, encryptionRequired, etc.

Next Steps

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