Slide 1
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

Slide 2
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

Slide 3
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 11
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
22/05/2017
Slide 12
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)
22/05/2017
Slide 13
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
