Why HTTP/2 for Telecom Signaling?

The 5G Core made a radical break from telecom tradition by choosing HTTP/2 as its signaling protocol. Previous generations relied on telecom-specific protocols like Diameter and GTP-C that required specialized tooling and expertise. HTTP/2 brings web-scale engineering to the mobile core with binary framing for efficiency, multiplexed streams over a single TCP connection, HPACK header compression that dramatically reduces overhead on repeated requests, and native support for RESTful API patterns. This choice opens the door for standard web development tools, libraries, and monitoring…
