Further milestone reached: Adaptation of BER network technology completed

Alterations to the “central nervous system” of the future Berlin Brandenburg Airport have been completed. Marcus Hänsel, Managing Director of Alcatel-Lucent Enterprise Deutschland, and Hartmut Mehdorn, CEO of Flughafen Berlin Brandenburg GmbH, put the new BER-NET into operation today.

Airport CEO Hartmut Mehdorn: “We have completed another important mile-stone on the way to the opening of the BER. The BER-NET is the central nervous system of the new airport. With these adaptations, we can now fulfil the requirements of our partners and users to a high standard. We can fur-thermore expand the BER-NET in future and adapt it to the increasing tech-nical needs of users at the airport.”

Wilhelm Dresselhaus, Chairman of the Board of Alcatel-Lucent Deutschland AG: “A powerful state-of-the-art data network is an important basis for suc-cessful enterprises. Berlin Brandenburg Airport now has such a network at its disposal, one that is fast and extremely flexible. IP service routers from Alcatel-Lucent and intelligent network infrastructure from Alcatel-Lucent En-terprise ensure that the requirements of the network users – the airport company, airlines, service providers and public authorities – are fulfilled optimally“.

The airport network includes IP service routers from Alcatel-Lucent along with intelligent LAN and WLAN infrastructure and voice communication solu-tions from Alcatel-Lucent Enterprise.

The data network originally planned for Berlin Brandenburg Airport, known as the BER-LAN, was planned, put out to tender, and ordered between 2006 and 2009 as a corporate network. The design envisaged that external part-ners would integrate homogeneously in the network structure as clients. The basis of a corporate network is the paradigm that all users comply with the specifications of the network operator. A total of around 360 different sys-tems operated by airlines, public authorities and other airport users access the central nervous system of the BER.

Paradigm shift brought the solution

As it turned out, however, customer requirements had risen significantly since the drafting of the original plans in 2006. The issue was analysed within the scope of the SPRINT programme. The recommendation derived from the results was to map the greater customer demands in the network and to implement them by upgrading to a carrier-grade network.

As a result, on 27 September 2013, the supervisory board approved the proposal by the airport’s management board and released additional funds of approximately 11 million euros to ready the network to meet future, more demanding requirements. The BER-LAN that was planned as a corporate network was redesigned within around one year into a more complex carrier technology, the BER-NET. The carrier technology offers customers guaran-teed services of high quality. Any disruptions occurring on the subnetworks of one partner will not adversely affect other customers’ systems or the overall network.

The BER-NET comprises approximately 1,000 network elements. Since, as part of the BER-LAN planning process, preparations had already been made for the development into a carrier network, it was not necessary to replace the entire network but only the distribution and server switches. The central component of the network, called the backbone, was retained. It was possi-ble to install the replaced switches as terminal device switches in the area of the control centres, thus saving costs during future expansion.

The new technology allows new user networks to be integrated in the BER-NET without difficulty. Even in the case of subnet overloads occurring, it is possible to continue transmitting safety-related services at the necessary level of quality.
