Description

RELATED APPLICATION The present disclosure is a continuation of and claims the benefit of priority to PCT Application No. PCT/CN2024/123841, filed Oct. 10, 2024, and entitled MESSAGE TRANSMISSION METHOD, APPARATUS AND SYSTEM, AND STORAGE MEDIUM AND DEVICE, which is based on and claims the benefit of priority to Chinese Patent Application No. 2023113143021, filed with the China National Intellectual Property Administration on Oct. 11, 2023 and entitled “PACKET TRANSMISSION METHOD AND APPARATUS, STORAGE MEDIUM, DEVICE, AND SYSTEM.” The above applications are incorporated herein by reference in their entireties. FIELD OF THE TECHNOLOGY The present disclosure relates to the field of network technologies, and specifically, to a packet transmission method and apparatus, a storage medium, a device, and a system. BACKGROUND OF THE DISCLOSURE Currently, with development of internet technologies, to satisfy data transmission requirements, increasingly large Ethernet frame packets need to be transmitted between networks. Therefore, more networks start to perform data transmission by using jumbo frame (also referred to as giant frame) packets. In a related technology, not all tunnels between networks support forwarding of a jumbo frame packet. If an intermediate network device on a tunnel between the networks does not support forwarding of the jumbo frame packet, the intermediate network device returns a piece of error information to the network. After receiving the error information, the network may confirm that the corresponding tunnel does not support forwarding of the jumbo frame packet. However, if the intermediate network device needs to return the error information, a processor of the intermediate network device needs to process and analyze each received data packet. As a result, load of the processor of the intermediate network device is excessively high, and performance and a response speed of the intermediate network device are affected. Consequently, it is difficult for the networks to detect whether the tunnel supports forwarding of the jumbo frame packet, causing a transmission failure of the jumbo frame packet, and reducing efficiency of packet transmission between the networks.
