Slide 104/19/23
WP3 Specification of Inter-domain QoS Analysis Architecture
WP3 part of the presentation for the Brussels review meeting on the
12th of march, 2003
Slide 204/19/23
Goal of INTERMON
enhance the inter working of tools for QoS and traffic
analysis in large-scale, multi-domain Internet networks
collect, process and present (in an automatic fashion)
information about:
Network topology, Traffic flows, QoS, and SLA fulfillment
using these instruments:
Topology detection and traffic measurement tools
Distributed information base
Analytical models and simulations based on measurements
Visual data mining techniques
Slide 304/19/23
Goal of WP3
integration of existing tools into INTERMON architecture
development of a scalable architecture for
integration of various components for:
topology discovery, traffic measurement,
traffic modelling, network behaviour simulation
data aggregation and visual data mining
building a common graphical user interface for data access
main focus of WP3: define the common interfaces for the
different tool classes, define control/data structures and
the component setup for the required connectivity
Slide 404/19/23
Subtasks of WP3
build central instance for toolkit control and communication
interfacing to other work packages
WP4: database access, topology detection, IPFIX meter
WP5: simulation and modelling
WP6: GUI and VDM
make data from measurement available to modelling,
simulation and visual data mining
coordination of control and data flows in order to implement
a system to run the proposed user-level
usage scenarios
Slide 504/19/23
WP3 Status
D2 document delivered in time (august 2002)
all selected tools have been set up by partners
integration has partially started, e.g. between
data sources and data collection
data repository and client GUI
not all interfaces completely specified yet
work on central control components and overall
integration work just started
integration within common GUI currently in progress
Slide 604/19/23
Architecture Specification
starting from the logical description of the INTERMON
architecture functionality stated in previous deliverables
additional design deliverable D4 was deployed in order to
address the following topics:
Scalability, Reliability, and Security
D4 represents the basis for next steps in the upcoming
implementation and integration phases
Three main system components (in addition to tools):
Global Controller (main data base, central control instance)
Local Controller (distributed local data bases, load balancing)
Tool Manager (tool specific control and data collection)
Slide 704/19/23
Further Plan
technical specification of remaining interfaces until April’03
specification of interaction of components within the
proposed usage scenarios until June 2003
refinement of graphical integration within common GUI
implementation work on central control components and
interfacing (middleware) to the existing tools and data
bases
integration meeting in June will produce first
‘all-together’ setup and enhanced testing possibilities
Slide 804/19/23
Innovations
centralized common control instance for numerous
instances of very different tools
abstractions from specific tools (e.g. different meters)
integration of different result types (routing information,
accounting records, QoS metrics)
connection of diverse components/services such as
traffic metering, modelling, simulation and visual data
mining in one analysis and visualization pipeline
Slide 904/19/23
Exploitation Plans
present open concept which allows easy
integration of further tools later on
cooperation with SCAMPI (high speed measurement)
and 6QM (IPv6 measurement) projects
contributions to standardization
( IETF IPFIX and PSAMP working groups)
InterMon Paper at IPS workshop
(bringing together IPFIX and PSAMP)
presentations at SCAMPI workshop (27.1.03, Amsterdam),
6QM meeting (7.3.03, Berlin), and TF-NGN meeting (7.02.03,
Rome)
Slide 1004/19/23
Topology Detection Demonstration
is part of the overall INTERMON demo
shows integration of Topology Detection toolkit into the
INTERMON system
local routing information collector watches routing
updates (just like a router does)
routing information is encoded in XML and send to
collection point (TD tool manager)
collected data can be viewed via GUI
