QUIC
QUIC (Quick UDP Internet Connections) is a modern transport layer network protocol designed by Google to improve web performance and security. It operates over UDP instead of TCP, reducing connection establishment latency and enabling multiplexed streams without head-of-line blocking. QUIC integrates TLS 1.3 encryption by default, providing enhanced security and privacy for internet communications.
Developers should learn QUIC when building high-performance web applications, especially those requiring low-latency connections like video streaming, online gaming, or real-time communication services. It's particularly useful for optimizing mobile and unreliable network environments, as it reduces connection setup time and handles packet loss more efficiently than traditional TCP/TLS stacks.
