Communication Protocols You Should Know: HTTP/2, gRPC, QUIC
Communication Protocols You Should Know: HTTP/2, gRPC, QUIC Three main protocols shape how data travels on the web today: HTTP/2, gRPC, and QUIC. They are designed to speed up connections, reduce delays, and make communication more reliable. Understanding them helps you pick the right tool for the job and avoid common bottlenecks. HTTP/2 fixes many issues of HTTP/1.1. It allows multiplexing, so many requests share a single TCP connection without waiting for earlier responses. It also uses header compression to save bandwidth. Because HTTP/2 runs over TCP, it gains reliability, but head‑of‑line blocking can still slow some flows if a single stream stalls. ...
