Why are TCP connections still the backbone protocol of the Internet after decades of software evolution? Alex Gizis and Speedify Lead Developer Kevin explain the major internet transport protocols TCP, UDP, QUIC, and MPTCP, and how each protocol handles data transmission, latency, and reliability across modern networks.
We look at layers of networking protocols, why TCP/IP remains dominant, how UDP trades reliability for speed, and what newer protocols like HTTP/3 (QUIC) are changing about the way the web moves data. Plus jumbo packets, MTU, FastTCP, Bufferbloat, IPv6 vs IPv4, and mmWave communication in the next generation of internet devices. Learn how Speedify’s protocol uses MPTCP-like logic and a TCP accelerator (Performance Enhancing Proxy) to optimize variable latency bonded connections across Wi-Fi, Starlink, 5G, and wired internet for faster, more resilient performance.
