Congestion Control in Networks: Optimizing Efficiency and Bandwidth Allocation

Protocol

This technical post breaks down congestion control mechanisms, focusing on the role of the transport layer. When multiple devices attempt to send an excessive volume of data simultaneously, the network can become overwhelmed. This phenomenon, known as congestion, leads to performance degradation, causing packets to be delayed or even lost. What Is Congestion Control and
