Abstract

One of the most important parameter of data communication is the tcp protocol. It has underwent many changes which brought into existence many variant of it like tahoe, reno, new reno, sack, vegas, westwood. Nowadays we are using tcp sack as the tcp variant as it is better as compared to its predecessor reno. With the software NIST Net we could emulate any kind of links and get the results with actual packets in consideration. The procedure of testing any network related protocol is first simulated and if the results are satisfactory than the emulation is done which is in actual a real test bed so if the output are satisfactory then it is directly used as a part of existing network. With Linux as the operating system installed in three computers and one of them acting as a router which has NIST Net installed in it; we could generate the all the parameter that need to be considered in data 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. All new protocols go through this testing procedure before getting into implementation. By getting these results we can know the difference in the throughput with the variants of tcp and get the comparison of reno and sack. Keywords: tcp variants, Emulator, NIST Net
