This article explains what head‑of‑line blocking is in HTTP, why HTTP/1.1 suffers from it, how HTTP/2 over TCP mitigates request‑level blocking but not transport‑level issues, and how QUIC over UDP fully resolves the problem.
This article introduces the QUIC transport protocol, explains its design goals and key features, details a practical iOS implementation using Chromium and Stellite libraries, presents code examples, and compares QUIC’s download latency against HTTP/2 on Wi‑Fi and 4G networks.
This article reviews the challenges of web performance, analyzes HTTP/1.1, HTTP/2, TLS, and QUIC protocols, discusses optimization techniques such as TCP fast open, TLS false start, server push, preconnect, and presents practical recommendations from the 2017 ArchSummit presentation.
With broadband speeds soaring, UDP’s simplicity and low latency now outperform TCP in web browsing, streaming, gaming, and IoT, as real‑world tests from Akamai and Google show dramatically lower packet loss, faster connections, and reduced buffering, signaling a shift toward UDP‑centric networking.
Ctrip's wireless development team shares a comprehensive overview of their app's network architecture, common performance pitfalls such as DNS and TCP issues, and a series of practical optimizations—including DNS caching, quality detection, priority handling, retransmission, payload reduction, and protocol upgrades—that dramatically improved service success rates and reduced latency.
