Traffic control method, traffic control apparatus and server

A traffic control apparatus applied to a device on a network side comprising a processor and a memory for storing program instructions, wherein the processor is configured to execute the program instructions to:

• determine a first queue delay based on transceiving time of a first communication data packet currently received from a user terminal and transceiving time of a second communication data packet received from the user terminal last time, wherein the first queue delay is queuing time of the first communication data packet in a buffer queue of a router;
• compare the first queue delay with a second queue delay stored by the device on the network side to obtain a delay duration, the second queue delay being queuing time of the second communication data packet in the buffer queue of the router, and the delay duration being a difference between the first queue delay and the second queue delay;
• determine that a network status of the user terminal is a normal status upon determining one of:
• the first queue delay is equal to the second queue delay;
• the first queue delay is greater than the second queue delay and the delay duration is less than a first threshold;
• or the first queue delay is less than the second queue delay and the delay duration is less than a second threshold;
• determine that the network status of the user terminal is an overload status in a case that the first queue delay is greater than the second queue delay and the delay duration is greater than or equal to the first threshold;
• determine that the network status of the user terminal is an idle status in a case that the first queue delay is less than the second queue delay and the delay duration is greater than or equal to the second threshold;
• predict a network bandwidth of the user terminal based on the network status of the user terminal and a reception data volume, the reception data volume being a data volume of the currently received first communication data packet or a data volume received by the device on the network side from the user terminal in a specified time interval;
• adjust a first quality of service parameter based on the network status and the network bandwidth of the user terminal to obtain a second quality of service parameter, wherein the first quality of service parameter is a quality of service parameter initially set for the user terminal by the device on the network side;
• and
• transmit the second quality of service parameter to the user terminal, wherein the user terminal transmits subsequent communication data packets based on the second quality of service parameter.

A server connected to a user terminal over a network, wherein the server comprises a memory and a processor, the memory stores programs, and the processor executes the programs to:

• initially set a first quality of service parameter for the user terminal;
• determine a first queue delay of a first communication data packet received from the user terminal in a buffer queue of a router, wherein the user terminal transmits the first communication data packet based on the first quality of service parameter;
• determine a second queue delay of a second communication data packet received from the user terminal in the buffer queue of the router, wherein the user terminal transmits the second communication data packet based on the first quality of service parameter, and the first communication data packet is transmitted immediately after the second communication data packet is transmitted;
• compare the first queue delay with the second queue delay to obtain a delay duration, the delay duration being a difference between the first queue delay and the second queue delay;
• determine that a network status of the user terminal is a normal status upon determining one of:
• the first queue delay is equal to the second queue delay;
• the first queue delay is greater than the second queue delay and the delay duration is less than a first threshold;
• or the first queue delay is less than the second queue delay and the delay duration is less than a second threshold;
• determine that the network status of the user terminal is an overload status in a case that the first queue delay is greater than the second queue delay and the delay duration is greater than or equal to the first threshold;
• determine that the network status of the user terminal is an idle status in a case that the first queue delay is less than the second queue delay and the delay duration is greater than or equal to the second threshold;
• predict a network bandwidth of the user terminal based on the network status of the user terminal and a reception data volume, the reception data volume being a data volume of the currently received first communication data packet or a data volume received by the device on the network side from the user terminal in a specified time interval;
• adjust the first quality of service parameter based on the network status and the network bandwidth of the user terminal, to obtain a second quality of service parameter;
• and
• transmit the second quality of service parameter to the user terminal, wherein the user terminal transmits subsequent communication data packets based on the second quality of service parameter.
