Return link performance in DVB-RCS2 template provides use case to build campaigns to simulate radio resource management (RRM) performance in return (RTN) link with one beam only. Modulation and channel coding according to DVB-RCS2 used for traffic transmission. On/Off traffic model is used to generate application level traffic. Template is implemented by the SNS3 simulator.
