This project aims to demonstrate that real-world TCP connections can effectively compete with simulated TCP connections for bandwidth within a controlled NCTUns environment. By setting up similar simulation cases, we investigate the interactions between contending TCP connections: one real-world and one simulated. The experiment assesses their coexistence and dynamic contention in a simulated network, providing insights into their behaviors through real-time data exchange and analysis. The results highlight the capabilities of NCTUns in modeling real and simulated traffic interactions.
