Quality of service management & scheduling in satellite networks

This thesis introduces the basics of the satellite networks and traffic control methods. Different packet level network simulators supporting satellite networks are compared. This thesis utilizes the NRT-simulator developed in ESA 4SSTB project.
During the thesis a DiffServ traffic control module for ns-3 is developed. The work introduces the structure and properties of this module.
The other point of focus is to define a simple simulation scenario for comparing different traffic control methods in satellite networks. This work compares the following traffic control methods: FiFo, DiffServ, and Fq-CoDel. The performance of the traffic control methods is compared in terms of throughput, delay, jitter, and packet loss.
