WP 4 Status
2
Objectives

• Development and integration of tools for
• Topology discovery in multi-domain networks
• Active and passive traffic and end-to-end QoS
  measurements at domain boundaries
• Design and implementation of a distributed
  database with policy-controlled data collection
• Contribution to the standardisation of traffic
  flow measurements in the IETF IPFIX (IP Flow
  Information eXport ) working group

3
Extensions related to TA

• The work carried out so far is consistent with
  what declared in the TA both in content and
  timing
• Novelty compared to TA
• Contributed to establishment of a new IETF
  working group on packet sampling (PSAMP) in July
  2002
• Co-chairing the IETF PSAMP wg
• Authoring one of the two current working group
  Internet drafts of the PSAMP wg

4
Overall Role

• WP4 has the following fundamental roles
• providing and integrating tools for the retrieval
  of real-world measurements data
• providing storage (database) for raw data and
  processed data
• The raw data will serve as input for
• Visualisation tasks (WP6)
• Modelling and simulation tasks (WP5)
• The tools developed will be the input for
• System integration, trial and evaluation (WP7)

5
Output(so far)

• D3 Specification of inter-domain QoS monitoring
  and structure discovery component delivered in
  time (Sept 2002)
• D5 Specification of inter-domain QoS database
  with policy-controlled data collection delivered
  in time (Sept 2002)
• Four IETF Internet drafts (ten versions)
• Nine Technical Papers

WP 4 Status

• WP 4 Deliverables
• D3 and D5 delivered in time (Sept 2002)
• D8 and D10 to be delivered by the end of March
  2003
• In time delivery expected

10
Status of D8 and D10

• D8 Prototype of inter-domain QoS monitoring and
  structure discovery components
• CM ToolSet (active measurements) tested in
  inter-domain scenarios
• MRT tool (ASes topology discovery) an adaptor to
  the INTERMON architecture developed
• Passive IPFIX flow meter first version as
  stand-alone tool designed, implemented and
  currently under test

11
WP4 Dissemination

• Technical papers
• 9 technical papers submitted and presented at the
  IPS Workshop (Salzburg, Feb. 2003)
• 1 paper submitted to ITC18
• Presentations on traffic flow measurements
• T. Tseby at SCAMPI workshop, Amsterdam, Jan. 2003
• J. Quittek at the Terena QoS Measurement and
  Monitoring Workshop, Berlin, July 2002
• Standardization
• Actively contributing to traffic measurements
  standardization at IETF
• Contributed to the establishment of a new IETF WG
  (PSAMP)
• Co-chairing IETF PSAMP

  IPFIX and PSAMP

12
Further Plan

• Integration of tools and database into the
  INTERMON architecture
• complete the interfaces to other components
• implementation of integration components (GC)
• possible integration of additional tools, not
  included in D8
• possible modifications/enhancements to tools
• collection of real data at FH Salzburg
• Contribute to trial demonstration
• Contribute to IETF IPFIX WG reporting on
  experience with the INTERMON IPFIX meter

13
Innovations

• Integration of a variety of monitoring and
  topology discovery tools in an advanced
  architecture
• Implementation of databases for storage of
  information contributed by different monitoring,
  simulation and modelling tools
• Information model for configuring an IETF IPFIX
  meter (which can serve to produce further
  contributions to the IETF)

14
Exploitation Plans

• TILABs implementation of a CISCO service
  assurance agent for inter-domain monitoring will
  be tested in Telecom Italia networks
• NEC will port the IPFIX meter protocol
  implementation to its HW router products
• TID will use the INTERMON topology discovery
  tools to coordinate multi-provider scenarios
• The experience gathered with the INTERMON passive
  measurements tools should support SR to set up
  new projects with national Telecoms
