Deep Dive into QUIC Protocol: Architecture, Features, and Optimization Strategies

The article thoroughly examines QUIC—the user‑space, UDP‑based transport underpinning HTTP/3—detailing its architecture, fast 0‑RTT handshakes, connection migration, stream‑level independence, congestion control, and flow‑control mechanisms, while also discussing implementation hurdles like 0‑RTT reliability, load‑balancer routing, UDP restrictions, CPU overhead, and real‑world performance gains reported by major Chinese tech firms.

Research on WiFi-Cellular Network Seamless Handover Technology for Mobile Devices

The article examines the delay‑inducing challenges of Wi‑Fi‑to‑cellular handover on mobile devices and proposes three complementary techniques—dynamic link evaluation, QUIC‑based connection migration, and multipath TCP—to reduce detection, link‑setup, and TCP‑reconstruction times, while weighing power, cost, and future AI‑driven trajectory prediction.
