Abstract

The invention discloses a message transmission method, a message transmission device, message transmission equipment and a readable storage medium, relates to the technical field of communication, and aims to solve the problem that a session source port is changed due to overtime aging and rebinding of NAT (Network Address Translation) mapping carried out on a QUIC (Query Unified Integrated Circuit) long connection session by NAT equipment. The method comprises the following steps: acquiring a first QUIC message from a QUIC client, wherein a connection identification field of the first QUIC message is used for identifying QUIC connection; according to the first QUIC message, obtaining a second QUIC message; a second QUIC message is sent to the receiving end; wherein the reserved field of the message header of the second QUIC message is used for uniquely identifying the QUIC connection, and the information in the reserved field is obtained according to the information in the connection identification field. According to the embodiment of the invention, the situation that the session source port is changed due to overtime aging and rebinding of NAT mapping carried out on the QUIC long connection session by the NAT equipment can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a message transmission method, apparatus, device, and readable storage medium. Background technique [0002] The QUIC (Quick UDP Internet Connection, UDP-based low-latency Internet Transport Layer Protocol) protocol uses UDP (User Datagram Protocol, User Datagram Protocol) as the transport layer. Many NAT (Network Address Translation) routers on the current network judge the connection by observing the SYN (synchronization), ACK (positive acknowledgement) and FIN (finish) messages in the TCP (Transmission Control Protocol) connection. establishment and termination of the NAT mapping table, thereby accurately maintaining the life cycle of the entries in the NAT mapping table. [0003] Many NAT devices in the existing network do not support the identification of the QUIC protocol. Therefore, the processing method in the prior art may cause the NAT device to p...
