“…This is accomplished with ping6. We follow Ayaz et al [16] by implementing the resource scheduling in the ground-station with a deficit round-robin scheduler. We use the implementation provided by dummynet; the high, medium, and low classes of services are weighted 100:10:1.…”

The VHF voice communication system currently used for air traffic control is experiencing increasing capacity problems. The "L-band Digital Aeronautical Communications System" is an upcoming technology providing an aeronautical datalink outside of the VHF band. The objective of this paper is to develop a method to emulate its communication performance. We developed a formal model of the system and implemented it on the basis of the dummynet network emulation tools. This implementation was deployed in a networking appliance and measured in a test-bed network. The results indicate that the emulator provides the performance predicted by simulations and is suitable to evaluate and verify protocols and applications envisioned to utilize this datalink.

The modernization of the European air transportation system will increase the need for data communication. This creates the need for large-scale simulations to ascertain that new aeronautical communication systems fulfil the requirements of future air traffic management communication. This paper presents a framework for such simulations based on service-oriented software architecture. The Framework for Aeronautical Communications and Traffic Simulations 2 (FACTS2) is based on the concept of service oriented simulation creating complex simulations from simple software building blocks called "services". Separating the tasks of services appropriately allows for natural parallelization at the service level. FACTS2 was applied to the simulation of European reference air traffic for the years 2007 to 2035 that will provide the basis for future aeronautical communication evaluations. It could be shown that the service-oriented simulation approach offers significant performance gains through parallelization scaling linearly with the number of available CPUs. The air traffic simulation results were validated against published simulation results to verify their correctness.

“…Having received the resource request of all polled aircraft, the ground-station assigns resources using an appropriate scheduling algorithm. There are two published implementations of LDACS resource schedulers by Gräupl [15] and Ayaz et al [16]. Both implementations are round-robin schedulers.…”
