HTTP 3

Problems in TCP|1000

In HTTP/2, we saw the TCP head-of-line blocking problem, i.e., TCP segments must be delivered in order.

HTTP/3 packet loss|1000

Therefore, the TCP segments have been replaced with UDP/QUIC datagrams. Here, the streams are independent, and the server does not care about the order.
If a datagram is lost, then except that stream rest, all will continue as it is.

Note

QUIC is a transport-layer protocol that provides several features to improve performance and security, while HTTP/3 is the application-layer protocol that benefits from these features to make server connections faster, more secure, and more reliable.
