METROlogie Pour L’Internet et les Services

SLIDE 2

Metropolis Project

Partenaries

LIP6 (Leader) France telecom R&D GET INRIA Institut Eurecom LAAS Renater

Funded by French Government (RNRT)

2 M€ projects 400 man.months over 36 months

Will end in late 2004

SLIDE 3

Aims

To develop a common framework for

metrology (science of measurements) of IP networks

QoS measurent and SLA Development of realistic models Protocol analysis and in vivo study of

network behaviour

Network dimensioning

SLIDE 4

Organisation

SP 1 : State of the art on metrology of networks
SP 2 : Classification and dimensionning
SP3 : Network measurement analysis
SP4 : Methodology for measurement and sampling
SP5 : Modelling
SP6 : Pricing and SLA
SP7 : measurement platforms

SLIDE 5

Measurement platforms

Active Measurements

RIPE probe NIMI architecture Pandora architecture

8 measurements point

Will go to 15 during the year

Combination of

RIPE or SATURNE probes for measurement NIMI like architecture for measurements consolidation

Pandora: A new measurement platform

Based on specific µ-kernel for measurement and

components architecture

Highly scalable, robust, and flexible

SLIDE 6

Measurement platforms

Microscopic Passive Measurements

DAG cards

3 GigaEthernet measurement points

3 academic, Generate around 80 Gbytes of data per day

Macroscopic passive measurements

Ipanema, QosMosMicroscopic passive

measurements

Flow level measurement

QosMos probe

Very precise flow classification and application analysis

Ipanema probe

One way delay measurement
