Herein is a research paper which depicts the use of emulation for testing purpose to illustrate the propagation of signals in the satellite communication. With the software NIST Net we could emulate any kind of links and get the results with actual packets in consideration. The procedure testing any network related protocol, link or equipment it is first simulated and if the results are satisfactory then the emulation is done which is in actual a real test bed so if the outputs are satisfactory then it is directly used as a part of the existing network. With Linux as the operating system installed in three computers and one of them acting as router which has NIST Net installed in it we could generate all the parameter that need to be considered in satellite communication. We can change the bandwidth, delay, drop rate with respect to congestion etc so that we could consider the parameters of actual links that will be involved and can get the idea of the throughput with the system and hence we could get the idea of the output we will be getting before hand. All new protocols go through this testing procedure before getting into implementation. Keywords: TCP, FTP, LEO, MEO, GEO, NIST Net, Congestion, Corruption.
