QUIC

This chapter describes what is QUIC and how to configure QUIC.

What Is QUIC?

Quick UDP Internet Connections (QUIC) is a UDP-based transport protocol. It has the following features:

  • It has excellent performance in weak networks and can provide available services in the case of packet loss and severe network delay.
  • All QUIC traffic is encrypted, improving transmission security.
  • It reduces the transmission and connection delay and prevents network congestion.

Supported Version

IETF-v1 (H3)

Prerequisites

An international HTTPS certificate has been configured. For details, see HTTPS.
  • Disabling the HTTPS certificate will disable QUIC.
  • After configuring the HTTPS certificate, wait about 5 minutes for the configuration to complete and then enable QUIC.

Precautions

  • QUIC cannot be enabled for domain names with special configurations.
  • QUIC cannot be used for origin pull.
  • This function is in OBT and is available for free trial.
  • If you change the certificate type from International to Chinese (SM2), QUIC will become invalid.
  • If you configure two certificates for a domain name, QUIC takes effect only for the international certificate.
