Experimental QUIC Protocol

Regarding the networking procedure, various layers are used for a great connection whenever we access the internet. Being one of the most trustworthy companies in Information Technology, Google aims to launch a QUIC Protocol based on UDP functionality.

UDP is generally a protocol with no connection and helps establish a great connection between the device and the server. QUIC Protocol will enhance the speed and help secure the connection more efficiently.

Experimental QUIC protocol Chrome Flag

  • Switching from TCP to UDP is always beneficial regarding connection establishment time. The message is converted into packets and then passed through the protocol.
  • Latency: Establishing a connection would take less time.
  • Multiplexing: Connecting to multiple networks without head-of-line blockage.
  • Uniqueness: Different stream IDs are provided for a unique identity.
  • Independent of Hardware.

Unfortunately, many firewalls (security for your system) do not detect the QUIC Protocol. This is a significant setback for the Security Protocol.

Here’s how you can enable it:

Go to Google Chrome, copy-paste the link, and hit the enter button.
