Embodiments of the present application provide a computer-implemented connection control method based on a QUIC protocol, comprising: receiving a QUIC connection request from a peer endpoint; analyzing the QUIC connection request and obtaining identification information of the peer endpoint; retrieving target historical information of the peer endpoint based on the identification information; adjusting a transport parameter based on the target historical information; establishing a QUIC connection with the peer endpoint based on an adjusted transport parameter; and controlling a connection state of the QUIC connection based on the adjusted transport parameter.
