Packet Scheduling Method, Network Device, Storage Medium, and Computer Program Product

A network device, comprising a memory, a processor and a computer program stored in the memory and operable on the processor, wherein the processor, when executing the computer program, implements operations comprising:

• acquiring an allowable queuing delay of a target packet in a shaper queue, wherein the allowable queuing delay represents a maximum queuing duration that a packet waits to be sent in a forwarding queue;
• acquiring a sending countdown time of at least one forwarding queue, wherein the sending countdown time comprises a first sending countdown time and a second sending countdown time, the first sending countdown time corresponds to a first sub-block in the forwarding queue, and the second sending countdown time corresponds to a last sub-block in the forwarding queue;
• comparing the allowable queuing delay with the first sending countdown time and the second sending countdown time to acquire a comparison result;
• and
• scheduling the target packet according to the comparison result.

A computer readable storage medium, storing computer executable instructions, wherein the computer executable instructions are used for executing operations comprising:

• acquiring an allowable queuing delay of a target packet in a shaper queue, wherein the allowable queuing delay represents a maximum queuing duration that a packet waits to be sent in a forwarding queue;
• acquiring a sending countdown time of at least one forwarding queue, wherein the sending countdown time comprises a first sending countdown time and a second sending countdown time, the first sending countdown time corresponds to a first sub-block in the forwarding queue, and the second sending countdown time corresponds to a last sub-block in the forwarding queue;
• comparing the allowable queuing delay with the first sending countdown time and the second sending countdown time to acquire a comparison result;
• and
• scheduling the target packet according to the comparison result.
