2. The background
Advanced networking is becoming increasingly popular in the field of the arts and humanities
Enabling collaboration
Sharing experiences
Creating virtual stages
In a way which is unimaginable only a few years ago!
GÉANT launch event performance:
Musicians in Stockholm
Dancers in Kuala Lumpur

3. Why research and education networks?
Many modern distributed artistic performances are using advanced networking
GÉANT and the European NREN infrastructures are ideal platform:
Accessible, high-quality (over-provisioned) IP network
Availability of point-to-point circuits
Support and expertise available within GÉANT
to facilitate the use of advanced networking for the arts
The challenge presented today:
Create a successful simultaneous performance
featuring dancers in Brasilia and Barcelona
performing together on a virtual stage
as if they were all in the same place.

4. Brilliant performances Crucial monitoring  perfSONAR
Advanced networking requires advanced monitoring
Monitoring an international scale:
gathering information from different network domains
The solution: perfSONAR MDM
The GÉANT multi-domain monitoring service
Interoperable on a global scale
Suitable for NRENs, research projects
Fully supported

5. The event: 3rd European Network Performing Arts Production workshop
Hosted by Gran Teatre del Liceu in Barcelona
Local technical support:
RedIRIS (Spanish NREN)
CESCA (regional network in Catalonia – Anella Cientifica)
Coordination:
TERENA
Internet2
technical expertise provided by GARR
Dates: 15, 16 and 17 June 2011
Topics: equipment & requirements for
Interactive performing arts education
Multi-site performance events, and
High quality netcasting over advanced networks

6. The dance performance: e-Pormundos Afeto
A joint dance performance between Brazil and Barcelona
Responsible:
e-pormundos afeto (Brazil)
the KONIC group (Barcelona)
Credits:
“Grupo de Trabalho de Midias Digitais e Artes" – Digital Media and Arts Working Group (2009/2010)
Developed the "arthron" tool for transmission
Responsible: Laboratorio de Video Digital headed by Prof. Guido Lemos
Supported by RNP (Rede Nacional de Ensino e Pesquisa) – Brazilian NREN
Directed by: Ivani Santana
Co-created with: Konic Theatre

10. The dance performance netowork requirements
Transmission requirements:
Source: Brasília (Brazil)
Destination: Barcelona (Spain)
Data estimation: Mbps (each direction)
Protocol: User Datagram Protocol (UDP)
No special requirement – best effort service
Operational Requirements:
Validate end-to-end connectivity
Verify any possible botleneck across different networks
Multi-domain troubleshooting infrastructure

11. The monitoring solution
The monitoring solution was based on perfSONAR MDM for Troubleshooting
perfSONAR MDM provided:
Reliable multi-domain monitoring
accessible through a common interface both in Europe and Brazil
The measurement and troubleshooting strategy:
Regular and on-demand bandwidth tests:
Using perfSONAR MDM in Europe and the Brazilian perfSONAR infrastructure
Test amongst main sites

12. A deeper look at perfSONAR MDM?
perfSONAR MDM (Multi-Domain-Monitoring) is the multi-domain monitoring service for the GÉANT Service Area (GSA)
Part of the GEANT portfolio
Based on the perfSONAR protocol
Interoperable with hundreds of deployments around the world
(from the perfsonar.geant.net website)
(from the perfsonar.geant.net website)

13. Link utilisation, input errors, output drops (RRD-MA)
Purpose:
Monitor link utilisation, input errors, packet drops
Provide access to historical measurements
Strategy:
Query router interfaces using SNMP from a perfSONAR server
Store data into RRD files
made accessible through web-service

14. Link Utilisation User Interface

15. OWD, jitter, packet loss, traceroute (HADES)
Purpose:
Monitor OWD, jitter, packet loss, traceroute variations
Regularly scheduled
On demand (to be implemented)
Provide access to historical measurements
Strategy:
Sending 9 packets every minute from pS server (Meas. Point)
Measure OWD, jitter, packet loss and tracking IP route
Store data into perfSONAR SQL-MA archive
made accessible through web-service

16. HADES User Interface – OWD, jitter packet loss

17. HADES User Interface – route comparison
Simple route comparison

18. Achievable bandwidth (BWCTL)
Purpose:
Measure the achievable bandwidth between two MPs
Regularly scheduled and
on demand (only for NREN NOC/PERT engineers)
Provide access to historical measurements
Strategy:
Run bandwidth test between MPs using a web-service interface to BWCTL
Display data with graph and store into perfSONAR SQL-MA archive
made accessible through web-service

19. Accessing Historical Bandwidth Measurements
Each dot is a measurement run.
Clicking on the dot a window displays the details

20. …and getting the results in two clicks from the web interface

21. perfSONAR Deployment: the domains involved

22. perfSONAR Available Measurement Points

23. perfSONAR Results RNP_Brasilia > ANELLA_Barcelona
GEANT_Madrid > RNP_Sao_Paulo
RNP_Sao_Paulo > REDIRIS_Madrid

24. Conclusions
With monitoring points on all key links, engineers from all the networks could
access network measurement data
from multiple domains in a standardised format.
work together, identifying potential issues on the intercontinental route
ensure a smooth network performance
take action to solve these before the event
confident that they were seeing the same information in a consistent format.
…and a configuration problem causing a poor bandwidth was actually identified and corrected
