DATA PACKET TRANSMISSION METHOD AND RELATED APPARATUS

摘要

Disclosed are a data packet transmission method and a related apparatus; the method comprises: obtaining the priority level value of an uplink data packet that needs to be transmitted; searching for a corresponding relationship between the set priority level value and a tunnel identifier according to the priority level value, each priority level value corresponding to at least one tunnel identifier; if a corresponding tunnel identifier is found, then transmitting the uplink data packet to a security gateway via a secure tunnel corresponding to the found tunnel identifier. The present invention can reduce the number of data packets determined by the security gateway to be re-transmitted data packets, thereby reducing the probability of packet loss.
