Final answer:
QUIC is a transport layer protocol that improves web application performance. If a QUIC Handshake fails, a renewing process is done to establish a successful connection.
Step-by-step explanation:
QUIC stands for Quick UDP Internet Connections. It is a transport layer protocol that aims to improve the performance of web applications by reducing latency and improving security. QUIC is designed to be used over User Datagram Protocol (UDP) instead of Transmission Control Protocol (TCP), which makes it faster and more efficient.
When a QUIC Handshake fails, it means that the initial process of establishing a connection between the client and the server is unsuccessful. In this case, the client and server need to go through a renewing process to retry the handshake and establish a successful connection. The renewing process involves going through the steps of the QUIC Handshake again, which includes verifying encryption keys, negotiating transport parameters, and confirming the connection.
