DECEA deploys SDN: Increased air traffic while improving safety levels
To prepare for the challenges of the future, the Brazil ANSP, DECEA, set out to enhance its network availability, reliability and safety. DECEA is achieving these goals by implementing a next-generation converged and hybrid ATM-grade network from Frequentis.
As DECEA rolls out the first software-defined air traffic management network in the world, it is gaining a range of benefits including greater operational flexibility and the capacity to scale without reducing performance. Critically, these enhancements do not come at the cost of safety: The ability to proactively detect and re-route around failures ensures exceptional service continuity.
Gaining nationwide network visibility
DECEA manages and controls air traffic across a vast area, which is split between multiple network provid-ers. It includes many regions where setting up basic telecommunications infrastructure is a challenge, and where network coverage is provided by very-small-aperture terminals (VSATs): Two-way satellite ground stations with dish antenna.
Case study: DECEA
“By deploying a Frequentis ATM-grade network with software-defined networking capabilities, we hope to substantially improve the way we deal with brownout scenarios in the future.“ Lt. Col. Eng. André Eduardo Jansen, Technical Director of CISCEA (The Commission for Implementation of the Airspace Control System, a department of DECEA)

Navigating towards a future- ready ATM networkDECEA is faced with 10 percent year-on-year growth in traffic entering Brazilian airspace, with no indications that this rate will decline anytime soon. Most conventional networks react only to total link loss, or black-out, events. However, situations where network performance degrades, or brown-out scenarios, can also have serious consequences for service levels, since conventional routing protocols cannot detect or rate these. Lt. Col. Eng. André Eduardo Jansen explains: “One of the current challenges we face relates to unstable quality of service of our telecoms infrastructure in brown-out scenarios within the network.”
Embracing a pioneering solution
To increase the efficiency, reliability and security of air traffic management in Brazil, DECEA deployed an ATM-grade, IP-based network delivered by Frequentis. As a hybrid solution that features SDN elements, it is the first of its kind in the field of ATM. The network converges different types of applications, from radio communication to operational data traffic, providing application-aware network flows and use-case-based bandwidth optimisations. It includes a network control layer that probes, monitors and controls the transmission of data for each type of application separately. Incorporating ED-137 compliant dynamic delay compensation over IP, VSAT and time-division multiplexing (TDM) based wide-area networks, the network ensures that radio communications are time-synchronised and have high audio quality. The solution provides ATM-grade network overlays that sit between the physical network components and the communication applications, eliminating the dependencies that existed between individual applications and backbone networks. Following extensive independent testing, DECEA is undertaking a phased implementation, with help from Frequentis.
Rock-solid foundations
Frequentis new ATM-grade network offers DECEA a high degree of operational flexibility, helping it to meet current and future demands.
By migrating from a static to a dynamic network infrastructure, DECEA reduces its network bandwidth requirements by an estimated 90 percent1) in compari-son to a standard enterprise IP network - translat ing into considerable cost savings.
Equipped with real-time monitoring and brown-out detection combined with intelligent routing, DECEA will be able to identify degradations before they im-pact operation and automatically move critical com-munications through alternative network elements, achieving new heights of service continuity. DECEA expects to achieve better than 99.999 percent end-to-end availability for the critical services, helping to maintain exceptional safety levels.
“We believe that the Frequentis ATM-grade network will help us achieve high availability and improved safety for our air traffic management and air traffic control systems.“ Lt. Col. Eng. André Eduardo Jansen, Technical Director of CISCEA
1) Bandwidth savings come from a combination of efficient 1:N streaming, radio main/standby handling, voice compression and ED-137B header compression. We are happy to calculate an estimate for your specific environment. Contact [email protected]
