Here, we want to discuss how connection and management of streams in HTTP/3 is based on RFC 9114. HTTP/3, which is built using the QUIC protocol, is specifically designed to improve performance and reduce latency in modern networks. One of the main advantages of HTTP/3 is its new connection management, which can eliminate the usual concerns regarding latency and network performance present in HTTP/2.
In HTTP/2, due to using TCP, any dropped packets can cause delays in data transmission, as the order of packets must be preserved and all of them must be re-sent until the order is properly restored. In contrast, HTTP/3 utilizes QUIC, which is a new layer transport protocol and can address this issue by using advanced techniques.
QUIC uses a series of built-in security mechanisms for encrypting data at the transport layer, providing enhanced security during transmission compared to previous protocols. By using UDP instead of TCP, QUIC can establish faster connections without the typical delays of TCP.
The establishment of connections in HTTP/3 is done using an initial SSL/TLS handshake, and since this protocol operates within a transport layer, the initial connections for users are much faster and can improve the loading time of web pages significantly.
The QUIC protocol also has the ability to manage different streams simultaneously, so if an issue occurs in one stream, it does not affect the other streams, a feature that may not be possible in HTTP/2 due to TCP.
<!-- The code below demonstrates a simple configuration structure for QUIC -->
{
"protocol": "quic",
"transport": "udp",
"security": {
"tls": "mandatory"
},
"version": "rfc9114"
}
Now let's examine the code line by line:
"protocol": "quic"
This line defines the protocol being used as QUIC.
"transport": "udp"
This line indicates that the QUIC protocol uses UDP as the transport layer protocol, which results in higher speeds and reduced latency.
"security": {"tls": "mandatory"}
This specifies that using TLS is mandatory in the security process, which ensures that the data sent is encrypted before being transmitted.
"version": "rfc9114"
This line indicates which version is being used, specifically referencing the RFC 9114 as the default herein.
