Whether it&rsquo;s webpage loading speed in web services, smoothness of live video streaming, inter-container communication in cloud-native applications, or download efficiency in P2P transfers, all rely on TCP congestion control to coordinate bandwidth allocation. A single BitTorrent node, for example, may maintain hundreds of concurrent TCP connections, and choosing the wrong algorithm can severely degrade bandwidth utilization. Since Van Jacobson&rsquo;s seminal 1988 paper at SIGCOMM, congestion control algorithms have evolved over nearly four decades — from heuristic loss-based methods to precise model-based measurement. This article covers 12 major congestion control algorithms, explaining their core ideas, strengths, weaknesses, and applicable scenarios, from Tahoe and Reno to CUBIC, BBR, and Copa.</p>
