EVALSOa high bandwidth
communication link for Paranal
ESO Lunch Talk - 2010/11/30

Why?
For very obvious reasons, Observatories tend to be built in remote areas where high capacity communication infrastructures are not normally available or easily accessible. This is the case for the ESO Paranal and the Cerro Armazones Observatories, located in the Atacama Desert, in the Northern region of Chile.
Although computing and networking infrastructures are available and continuously evolving at the sites, the possibility to fully exploit in real time such facilities is limited by the available bandwidth to connect them to the rest of the research and academic world. To fully exploit such remote sites (from fast data transfer to rapid response mode, from remote monitoring and engineering to virtual presence) high capacity links, i.e., bandwidth >Gigabit-per-second (Gbps), are necessary.
The start
Driven by this idea, a consortium of 9 members has been created in 2007 aiming to create a physical infrastructure (and the tools to exploit it) to efficiently connect the the ESO Paranal and the Bochum Cerro Armazones (OCA) Observatories to Latin American network and from there to Europe.
The project builds on the National Research network of Chile (REUNA) and International infrastructures created in the last years with the EC support (RedCLARA, GEANT) to provide Latin American and European Research a competitive edge by having faster access to the collected data and using the connected facilities in an ever more efficient way.
This proposal was presented at the European Commission Frame Program 7 and in late 2007 was granted co-funding.
Enabling Virtual Access to Latin–America Southern Observatories
… was born!
EVALSO
• SA1: Upgrading of the communication infrastructure
• JRA1: Fast Data Access• Will aim at drastically improve the time needed for making the data available
from the moment of the physical observation.
• JRA2: Virtual Presence • Will plan and produce the tools that
could be used to make possible the virtual presence of scientists, engineers, and experts at remote facilities and, to the extreme, the possibility to perform remote observations.
• JRA3: New observing modes • Will investigate and concept prove new
observing modes made now possible by the availability of the fast link and the tools developed by JRA2.

Some Remarks
• EVALSO cannot be considered the ultimate solution• Continental infrastructures have to be coordinated to remove the
bottlenecks, especially between Latin America and Europe• The limiting element in the chain is now the intercontinental link capacity
and its cost
But in the meantime let us be happy for making the first step …• … and let me thank and congratulate the people in the different
organizations who have worked really hard to make this first achievement of EVALSO a reality
• … within budget!
(Fernando Liello, Project Coordinator, Universita’ di Trieste, from his presentation at EVALSO Launching event)
Current and future use
Till the end of the EVALSO project (mid2011), it will be available for the Research Activities of the EVALSO Consortium. After that time, the infrastructure will be used according to mutual agreements that are being discussed among ESO, OCA, and REUNA.
Some key concepts:• ESO will be responsible for the maintenance of the optical infrastructure;• REUNA will be responsible for the maintenance of the DWDM equipment
and for the network operation for all nodes;• Dedicated channels are established between: OCA and
REUNA/Antofagasta, ESO/Paranal and ESO/Santiago, REUNA/Antofagasta and REUNA/Santiago, ESO/Santiago and REUNA/Santiago;
• More channels may become active as result of future projects and agreements.
Example: OCA
Thanks to the availability of high bandwidth communication to the observatory infrastructure, the AIRUB(OCA) plans to:
• reduce travel waste (people time, money, CO2) thanks to remote real-time control of telescopes and robotic operation
• reduce data transfer costs by replacing shipping over hard disks• allows immediate response to newly discovered variable phenomena• use remotely controlled telescopes with good video and audio quality links
as part of the educational process (teaching and/or training) without need for expensive traveling and therefore more affordable for the students/university
