WP 4 Status

Slide 204/19/23

Objectives

Development and integration of tools for:Topology discovery in multi-domain networksActive 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

Slide 304/19/23

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 wgAuthoring one of the two current working group

Internet drafts of the PSAMP wg

Slide 404/19/23

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)

Slide 1204/19/23

Further Plan

Integration of tools and database into the INTERMON architecture:complete the interfaces to other componentsimplementation of “integration components” (GC)possible integration of additional tools, not

included in D8possible modifications/enhancements to toolscollection of real data at FH Salzburg

Contribute to trial demonstrationContribute to IETF IPFIX WG reporting on

experience with the INTERMON IPFIX meter

Slide 1304/19/23

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)

Slide 1404/19/23

Exploitation Plans

TILAB’s 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
