This paper is devoted to the study of the effect of packet loss on the effectiveness of the TCP and UDP network protocols. During the experiment, a Python script was used to simulate data transmission over these protocols, taking into account packet loss, as well as network settings that allow simulating different loss levels. Based on the collected data, latency, bandwidth, and response time were measured when the percentage of packet loss changed. The results of the experiment showed that TCP is more sensitive to packet loss, which leads to increased latency and reduced throughput. In contrast, UDP exhibits lower latency, but is less reliable at high levels of data loss. The work highlights the importance of taking packet loss into account when designing network applications and infrastructure, and provides recommendations on choosing protocols for various types of network services.

Keywords:network protocols, TCP, UDP, packet loss, latency, bandwidth, response time, Python script, loss modeling, data transfer efficiency.
