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

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.

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

requirements
Transmission requirements:
Source: Brasília (Brazil)
Destination: Barcelona (Spain)
Data estimation: 25-30 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

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

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)

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
connect • communicate • collaborate
Link Utilisation User Interface

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

HADES User Interface – OWD, jitter

Simple route comparison

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 SQLMA archive
– made accessible through web-service

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
