QUIC also solves the problem inherent to the extremely fast pace of life. With QUIC the number of round-trips is reduced to one. A typical handshake you get consists of two round-trips: first, a TCP connection is established and then the TLS layer encrypts the connection. These features are typically performed by a higher-level protocol, such as TLS. It lives up to its name by doing things quicker than its established analogues.įirst and foremost, it is due to the fact that QUIC provides security features, like encryption (opens in new tab) and authentication, from the transport protocol itself. QUIC is a transport layer network protocol built on top of UDP, which transmits packets of data between servers or between a server and a client. This can slow the traffic speed down significantly, and as the demand for uninterrupted Internet connectivity across different networks grew, so did the need for a new, faster and more reliable solution. That means that if one of the response packets gets lost because of the weak connection, the rest of them will have to wait in line until the lost packet is re-sent, hoping that it gets through this time.
