The present disclosure provides communication techniques based on QUIC transport protocol. The communication techniques comprise receiving a first handshake message sent by a client computing device; defining a second handshake message in response to the first handshake message, wherein the second handshake message includes an encrypted-transport tag and a plaintext-transport tag; sending the second handshake message to the client computing device for selecting, based on the second handshake message, a target transport mode from a plurality of transport modes; receiving a third handshake message sent by the client computing device, where the third handshake message includes identification information of the target transport mode; and performing data transport based on the target transport mode.
