This paper evaluates the effects of bandwidth asymmetry introduced in a geostationary DVB-RCS satellite architecture on the round trip time of the transmission control protocol (TCP). In particular, it shows the analytical approximation of the round trip time (RTT) of a TCP connection and defines a bandwidth asymmetry index, which is the key point of the work. The final goal is the provision of analytical equations approximating the RTT behavior over asymmetric satellite networks in strict dependence on the asymmetry index. It can help design DVB-RCS system and evaluate their performance. The results are compared with the values obtained through the ns-2 simulator
