Simulation of GEO satellite on LAN

Satellite systems play significant task in the telecommunications infrastructure. They can interconnect various remote geographical areas or deliver multimedia services to many geographically dispersed and outlying "islands". Unfortunately, the satellite systems suffer from some drawbacks which influence data transmission. That is why it is necessary to simulate performance of various current and future protocols planned to use for data transmission on the satellite channel. This contribution introduces a product we made for simulation of the satellite environment on LAN.
