Steps to unable QUIC in the Browser

What is QUIC Protocol?

As we know Protocol is a rule regarding how the data is communicated, how the data is transferred between two mediums, encryption standards, etc., QUIC Protocol is the same that was developed by Google INC. in the year 2012 and owned by itself. Without delving into its history, we will see the working & usage of the QUIC....

Where QUIC is used?

QUIC, commonly known as HTTP/3, which is Version 3 of HTTP-based communication. We all know that HTTP Protocol is used in web technology to request data from the remote web server & present the data in the browser. The data may be anything such as images, text, video, audio, etc., HTTP will fetch those data from the server & present it in the visualized format in the browser....

QUIC – the replacement of TCP + TLS

HTTP works in the application layer and uses the TCP as its backend to communicate with the web server with its Handshaking mechanism. If TLS-enabled communication is enabled, then it will do the additional process to ensure that HTTPS Connection is secure & it’s a valid certificate from a third party....

UDP Usage in QUIC

QUIC Protocol is running on the top of UDP. UDP is connection less & unreliable in data transmission. TCP standard is fame due to its reliablity. QUIC just extends the UDP as reliable connection provider here with some advanced techniques. So, due its fastness and reliable communication, the communication between the Client-server is both fasty and reliable. So, less data loss is there....

Steps to unable QUIC in the Browser

Now a days, by default QUIC Protocol is enabled in the recent versions of chromium based browsers such as Google Chrome, Microsoft Chromium Edge, Vivaldi, So if the site supports HTTP/3 website, the request took the HTTP/3 based protocol....

Steps to see uses of QUIC for its communication in web Browser

Open Browser In a new tab, open the devoper tools -> Network tab Search for site (www.google.com) Right Click the row header(Name, Status, ..), there you can find the header named Protocol -> choose it If its http3 or h3, then it is using the QUIC Protocol for its communication....

Pros of QUIC Protocol

Due to its running based on UDP, no such overwhelming adoption is needed. Reliablity based UDP makes the connection faster. Security mechanism is handled based on existing TLS mechanism....

Cons of QUIC Protocol

As it is a new protocol so, not all browser support it yet. This can leeds to compatibility issue. This protocol is not based on traditional TCP so it may not support all the debugging tools, that will make a challage to Network administrator. Flow control mechanism needs to be handled properly. It’s congestion control mechanism is different from TCP that shows different behaviour in terms of Congestion-aware....
