Web performance to become faster with HTTP3

Web performance to become faster with HTTP/3             According to the officials at the Internet Engineering Task Force (IETF) which undertakes ratification of the key standards buttressing the internet and the web, the third official version of HTTP protocol may be launched soon. It will be called HTTP/3. This is being attributed to Google’s campaign to make the web performance even faster as this next version of the core protocol will be based on the technology that originated with the search giant. If it passes muster, it will be the second experimental technology developed by Google to become an official HTTP protocol upgrade, the first one being Google’s SPDY technology that was the foundation of HTTP/2.                

In 2013, a new experimental protocol was introduced by Google by the name Quick User Datagram Protocol (UDP) Internet Connections {QUIC} which aimed at making HTTP requests faster and more secure. It is capable of making network connections faster by reducing the number of round trips that one computer has to make when downloading information from another over HTTP. QUIC was proposed as a draft standard at the IETF in 2015. One year later, the idea of running HTTP requests using QUIC instead of TCP was proposed by Google in 2016. TCP has been inherent in internet communications since the mid 1970s and has supported the web since its beginning.     

Essentially, HTTP over QUIC is a rewrite of the HTTP protocol which is framed on top of Google’s QUIC instead of TCP as its base technology. QUIC is a rewritten version of the TCP protocol as an improved technology that combines HTTP/2, TCP, UDP, and TLS, to name a few. Tests have proved QUIC to be faster and more secure owing to its encrypted-by-default implementation. Hence, Google wants QUIC to slowly replace both TCP and UDP as the new protocol of choice for moving binary data across the Internet. Since 2015, HTTP over QUIC support has been added not only to Chrome 29 and Opera 16, but also to LiteSpeed web servers. While in the beginning, it was only Google’s servers that supported HTTP over QUIC, since last year the technology has also been adopted by Facebook.
