Spanish airport & air navigation management
Spain is the second largest tourist destination in the world. With
over 55 million visitors in 2005, the infrastructure and management
of transport services has to be world class to cope with the
increasing demand. As a result of high seasonal visitor numbers
flying into Spain, aviation authorities require class-leading technology
to handle the millions of passengers that pass through Spanish
airports every year.

About the company

Aena is the public business entity for airports and air navigation
management in Spain, controlling 47 airports and one heliport.
During 2005, the airports under Aena management saw over 181
million passengers, operated 2 million aircraft, and transported
more than 654,000 tons of cargo.
Currently Aena is undergoing a major airport expansion program.
A 6.2 billion euro expansion of Madrid Barajas International
Airport was inaugurated in 2006. Major expansion at Barcelona
International Airport and Málaga Airport will be finished by 2008.
Many of the other airports in the network will be expanded to
accommodate the increasing air traffic demands.

The Challenge

When Aena began to plan this extensive project, one of the most
important considerations was outfitting their airports with the
most modern and secure network installations available. This was
to ensure management, security and airport operation data was
afforded the highest possible performance and reliability. Also
remaining scalable for future expansion was a key criterion.
Having traditionally used ATM technology, Aena decided to change
to Ethernet for all network connection and data communication
needs. This included use of Fast Ethernet, Gigabit Ethernet, and in
the future 10 Gigabit Ethernet, making use of leading technology to
future proof their network design and infrastructure.
Aena wanted to deploy state-of-the-art multi-service networks with
built-in redundancy, bullet-proof reliability, and local support to meet
their infrastructure mission statement of Quality, Security, Service.
Aena is upgrading its aeronautical facilities in order to meet air traffic
demands with the highest safety and quality standards.

The Solution

In the last two years Allied Telesis have won 15 networking projects
in 14 Aena managed airports.
Aena network infrastructures incorporate the latest multimedia
elements, inter-connecting all of the security and communication
equipment, including cameras, x-ray machines, and smoke
detectors, along with airport operation data.This creates a safer
environment and also allows data to be immediately transferred to
save passenger time.
The networking company chosen to meet these requirements
needed to provide class leading technology and an established
support structure.
"For us, local support by the network equipment manufacturer is
essential, and Allied Telesis fullfills this requirement. Also, Allied
Telesis' long history and experience in the networking market
guarantees the quality of their products" said José Carrasco (Aena's
Communications Manager).
The Allied Telesis solution utilizes a generic network structure that
comprises a redundant Layer 3 core for high reliability and traffic
throughput. This network core is connected with Gigabit fiber links
to Layer 2+ or Layer 3 distribution switches, which provide the
security and features required for each specific airport installation.
Vigo and Salamanca Airport networks, described in the following pages,
highlight some of the Allied Telesis solutions employed for Aena.
