Airspace Q4 2018: Intelligent networking for future ATM

17 December 2018

Consistent and reliable network performance, without service interruption is essential for air traffic management’s safety-critical environment.

In 2018, Frequentis responded to this need with software defined network technology. Its vitalsphere NetBroker ensures the service continuity and performance required of an ATM-grade network through the use of real-time network performance information and a set of application-specific performance targets with the ability to switch single voice and data flows between networks when performance is reduced.

It has completed the upgrade of the Caribbean satellite telecommunications network, MEVA-III, to support IP-based applications for faster and more secure voice transmissions, as well as more reliable transmission of AFTN/AMHS (aeronautical fixed telecommunication network/aeronautical message handling system) and surveillance data.

The network of 18 nodes for 15 ANSPs at sites in the Caribbean, Latin, Central and North America is an important part of ICAO’s work to create a phased transition from legacy communication technology in the Caribbean, increasing the efficiency of local ANSPs.

Previously, the MEVA network, which provides interactive voice and data telecommunications services between international air traffic control facilities and other regional telecommunication networks in the region, was restricted by coverage limitations and quality. The service now offers the highest efficiency and 99.9% availability, as well as a reduction in operating costs by allowing payment only for the received network service.

The implementation of intelligent networking in ATM also adds a valuable performance layer to support remote and digital technology towers, system-wide information management and modern surveillance technologies, which require more network bandwidth, more data sharing and more flexibility in communication flows.

NetBroker monitors network performance, and proactively re-routes traffic flows based on the importance of the application or priority of the communication, ensuring customer specific air traffic and safety demands are met.
