Measurement Tools in PlanetLab Europe

Measurement Tools in PlanetLab Europe

Tanja Zseby (Fraunhofer FOKUS, Berlin, Germany)(some slides from other OneLab partners)

An Open Federated Laboratory Supporting Network Research for the Future Internet


PlanetLab Europe (PLE)

● PLE: PlanetLab Nodes in Europe

Managed by PLE office in Paris

In cooperation with PlanetLab Central (Princeton)

● Supported by the EU FIRE Project OneLab

Development of measurement tools for PLE users

Integration of new testbed types: wireless, DTNs, autonomic, etc.

Federation with other testbeds (PLC, G-Lab,…)


Measurements in Experimental Facilities

● Support facility operation

Control correct operation of facility, incident handling

Planning, understanding users, statistics, reporting

● Service to users: Before, during, after experiment Experiment Supervision: capture results of experiments,

parameters under investigation

Environment Supervision: captures parameters not under investigation that may be relevant for experiment outcome

Measurement Service: provide measurement data to algorithms that require such input (routing, adaptation, learning functions).

Special capture card

● Deployment in Progress

22 OneLab project partners


Topology Information Overview

Example: ETOMIC - Active Measurements

● Active Measurement Infrastructure

Sends packet bursts

Parameters can be configured by user

● Web interface: https://etomic.tlm.unavarra.es

Upload measurement experiment

Execute measurement experiment

Download results

● Periodic measurements database

Scheduled measuremements available to users


Passive Measurements: CoMo Box

CoMo Features:- Resource control- Customer modules upload- Controlled access to results


Multipoint Packet Tracking

● Passive measurement of path, OWD, loss, etc.

● Based on hash-based sampling

● Support for P2P, multipath routing experiments, etc.

● Different Options

On PlanetLab nodes directly

On ANME with hardware support for capturing and clock sync

Lightweight probe available for mesh nodes (OpenWRT)

● Demo at SIGCOMM 2010


Multipoint Packet Tracking

Select same packet at different observation pointsSelect same packet at different observation points

Selection Processes:Filtering: f(ci) parts on c remain can select same packets Sampling: f(si) or f(ti,) s, t change cannot select same

<sA, tA, c1><sB, tB, c1> <sB, tB, c1>

Henke. Schmoll, Zseby: Empirical Evaluation of Hash Functions for Multipoint Measurements, ACM CCR, 2008 and RFC5475


IP Flow Information Export (IPFIX)

● Protocol for exporting Measurement information

RFC since 2008, very active IETF group

● Used for data export for passive measurements in PLE

Packets, flows, QoS values

Own new information elements

● IPFIX File format for data storage

● Packet and Flow Selection Techniques

● Contribution to Standardization

● libipfix: http://net.fokus.fraunhofer.de/libipfix/


Next Steps

● Common entry point for access to measurements

Guidance for experimenters for measurement service

Support for installation of measurement boxes

● OMF Integration

Measurement configuration as part of control framework, result data via IPFIX

● Deployment in G-Lab (some tools)

● Exploring the use of perfSONAR

● Cooperation with GENI I&M ?


Next Steps

● Integration of further tools?

Many tools Standardized methods, IFs required

MOME DB stores Tools & Traces

● Federation challenges

Coordinate measurements among multiple administrative domains

Parameter settings, costs, etc.

Standards !
