  • Gerhard Münz, Benoit Claise
  • 70th IETF Meeting, Vancouver, 2007

2
Reviews received for -02
  • We received three thorough reviews. Thank you
    very much!!!
  • Comments about how to improve the text
  • add note of caution concerning configuration of
    Template IDs
  • done in -03
  • problems to understand configuration of a
    Metering Process as combination of Selection
    Process instance(s) and one cache instance
  • hopefully better explained and motivated in -03
  • configuration data model is also useful for
    storage of configuration data
  • mentioned in the introduction of -03

3
Reviews received for -02
  • Comments concerning the XML Schema
  • request for direction parameter for
    ObservationPoint-gtLincard/Interface
  • added in -03
  • request for description attribute which can be
    used for annotations
  • added in -03
  • request for integration of file input/output
  • started with FileExport as new export option in
    -03, solutions for configuring file input is
    subject to ongoing work
  • request for ACL-like filters (OR filter is
    missing)
  • consensus is required as only AND is specified in
    PSAMP-TECH
  • request for configurable packet size and delay
    caused by Exporting Process
  • propose to use device-specific extension of the
    model if such configuration parameters exist
  • request for observationPointId parameter
  • added in -03, as well as exportingProcessId,
    meteringProcessId, selectorId (all optional,
    configuration does not have to be supported by
    device)

4
Additional changes in -03
  • Text
  • many small changes aiming at increasing the
    comprehensibility
  • Configuration data model
  • configuration of Exporting Process restructured
  • Reporting class is now called Option class
  • UML
  • removed id attributes from diagrams which are
    needed for references in XML ? class diagrams now
    only show configuration parameters

5
To be done/open issues
  • File export
  • configuration of a collector writing received
    data into a file
  • Add the possibility to directly link the
    collecting process to an exporting process with
    FileExport?
  • File import
  • raw packets add a file-based Observation Point
    (e.g. pcap file)
  • IPFIX/PSAMP records add a file-based Collecting
    Process
  • Do we need this second option? Is anybody
    deploying such a configuration?
  • Selection Process
  • check if current configuration corresponds to
    PSAMP view
  • SCTP
  • add PR-SCTP related parameters

6
Relationship to Netconf
  • Comments received
  • recommend but do not mandate
  • protocol-independence is an advantage
  • no-one requested to force the usage of Netconf
  • Suggestion
  • keep the configuration data model
    protocol-independent
