HTTP/2 is the second version of the hypertext transfer protocol and brings two significant improvements: more efficient network resource usage and reduced latency. Latency (the elapsed time between the user sending a request to the server and receiving the response) can either increase or decrease according to the way network resources are handled, so higher latency means a longer wait for the user. To reduce latency, HTTP/1.1 implemented a request pipelining technique, allowing TCP connections to send multiple requests without waiting for a response. However, although request pipelining facilitates concurrency, it does not avoid head-of-line (HoL) blocking, which occurs when a single data packet queue blocks subsequent transmissions while waiting for a response. This phenomenon affects both the TCP and HTTP protocols, so it appears at both the Transport and…
