What are the benefits of QUIC?
Posted: Mon Dec 09, 2024 8:39 am
The benefits of QUIC are numerous and, as it is the protocol that HTTP/3 is based on , examining them is important to understand how the network is evolving . The improvements are several as Nicholas Marmonti explains in his article on QUIC and HTTP/3. Now, make yourself comfortable, because we will analyze them together.
Meanwhile, continuing to talk about Round Trip Time , services that are particularly sensitive to latency (such as web searches) benefit from zero-round-trip connections . Accessing an HTTPS page requires communication that takes 2/3 cycles with the server to establish a secure connection before the browser downloads the page.

With QUIC things change because the protocol is designed so that, if a client has already communicated with a server, it can start sending data without waiting times . Result? A much faster client-server-client response . Even an optimized site like Google gets a 3% improvement !
The improvement brought by QUIC is similar to TCP+TLS+HTTP/2 , but implemented on the UPD network protocol . However, TPC is an integral part of the operating system kernel and therefore making significant changes is quite complicated . It would be necessary to work on releases that have an impact at the system level and are usually distributed slowly on servers.
QUIC , on the other hand, reduces the limitations by making it unnecessary to update the system kernels because it moves its operation into user space. Furthermore, being based on UPD, it guarantees optimal performance for users connected to slow or high-latency networks , since it handles requests differently compared to the protocols used previously.
Other important advantages brought by QUIC , besides the faster connection, are:
Multiplexing support ;
FEC packets , Forward Error Correction, a kind of backup;
Congestion control ;
Authentication and encryption to defend against possible attacks;
Greater compatibility ;

introduced by QUIC, I'm sure you'll want to know how to check if it's active .
The process is very simple: just use the Chrome DevTools of Google Chrome and load a page, remembering to keep the Network panel open. Now look in the Protocol column and note if the string is present: http/2+quic/43 . If it is, then it means that that domain is using QUIC .

It is worth reminding you that if you use Siteground as hosting you are probably already taking advantage of QUIC because support for sites hosted on the servers has been activated for some time now.
Cloudfare , on the other hand, says that its customers will be able to activate HTTP/3 through an option in the dashboard to enable support. Then, when users visit a website from a client with HTTP/3 support, the connection will be automatically established using the new protocol and not the older versions.
HTTP/3 the web of the future has arrived!
If you've come this far, you'll agree with me on the importance of HTTP/3 , whose improvements make the web an increasingly efficient environment and projected towards a not-so-distant future!
To summarize in a few sentences what has been reported, HTTP/3 is the latest version of HTTP , the protocol through which the contents of web pages are transferred from servers to clients: it is a protocol different from all its predecessors that has introduced fundamental innovations. The protocol has been entirely rewritten, using QUIC instead of TCP, and the TLS cryptographic protocol has been used .
The changes introduced aim to make the web faster , safer and improve the browsing experience for every user. If you still have doubts about the UDP protocol adopted by HTTP/3 and want to understand how to make the most of this innovation to make your website even more performing , but you don't know where to start, press the button below and let's ge
