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
