Data packet transmission method and related devices

A data packet transmission apparatus, comprising:

• a memory operable to store computer-readable instructions;
• and
• a processor circuitry operable to read the computer-readable instructions, the processor circuitry when executing the computer-readable instructions is configured to:
• obtain quality of service profile information of a target service flow from a session management function network element,
• the quality of service profile information comprising a first data detection rule and a first processing rule,
• the first data detection rule comprising data packet set type internal identification information corresponding to at least one data packet set type of the target service flow and further comprising at least one of a data set sequence number of the data packet set type or a data packet sequence number within a data set of the data packet set type,
• the first processing rule comprising a processing rule corresponding to the data packet set type, and the processing rule corresponding to the data packet set type comprising packet loss processing information corresponding to the data packet set type;
• receive a data packet to be forwarded;
• determine whether to discard one or more data packets within the data packet set type according to the packet loss processing information in response to the data packet set type internal identification information of the data packet being matched with the first data detection rule;
• and
• determine data packets to be discarded within the data packet set type in response to determining to discard one or more data packets.

A non-transitory machine-readable media, having instructions stored on the machine-readable media, the instructions configured to, when executed, cause a machine to:

• obtain quality of service profile information of a target service flow from a session management function network element,
• the quality of service profile information comprising a first data detection rule and a first processing rule,
• the first data detection rule comprising data packet set type internal identification information corresponding to at least one data packet set type of the target service flow,
• the first processing rule comprising a processing rule corresponding to the data packet set type and further comprising at least one of a data set sequence number of the data packet set type or a data packet sequence number within a data set of the data packet set type, and
• the processing rule corresponding to the data packet set type comprising packet loss processing information corresponding to the data packet set type;
• receive a data packet to be forwarded;
• determine whether to discard one or more data packets within the data packet set type according to the packet loss processing information in response to the data packet set type internal identification information of the data packet being matched with the first data detection rule;
• and
• determine data packets to be discarded within the data packet set type in response to determining to discard one or more data packets.
