The main goals of this project are to learn about the different TCP models in NS3, learn about Congestion Control Algorithms, discover the NS3 environment, do some measurements in TCP based on the NS3, and investigate the ability of the Network Simulator software (NS3) for applying different computer network environments. At the end of the project, the student will be able to write his own code on NS3 or merge the available example codes of NS3 to apply different network scenarios.

Previous and current networking paradigms always introduced new technologies incorporated in various applications over the internet. Some of them demand high transmission throughput or low delay, which led to new issues since it increased the traffic over the internet. Congestion refers to the issue where the processing is slower than the receiving rate. Such an issue causes packet loss and, in some cases, collapses the whole network. Thus, it is crucial to address such problems by implementing a congestion control algorithm to handle such cases. No congestion control mechanism was implemented in the original standardized TCP design. Later, new mechanisms were designed, such as slow start, congestion avoidance, additive increase, multiplicative decrease, etc. Finally, new variants of TCP appeared to manage the congestion window differently, such as TCP Tahoe, Reno, NewReno, Vegas, Hybla, etc. This project aims to implement the specified TCP variants and analyze their performance in different network conditions to create a comprehensive and generalized idea regarding their performance.
