Packet scheduling method, related device, and computer storage medium

A packet compensation apparatus, comprising:

• a non-transitory memory storing instructions;
• and
• a processor coupled to the non-transitory memory;
• wherein the instructions, when executed by the processor, cause the apparatus to be configured to:
• receive a to-be-scheduled packet, wherein the to-be-scheduled packet is a packet sent by a network side to user equipment;
• and
• obtain an actual packet length of the to-be-scheduled packet, wherein the actual packet length indicates a total length of the to-be-scheduled packet, wherein
• determine a first compensation value and a second compensation value based on the to-be-scheduled packet, wherein the first compensation value indicates an estimate of a variation relative to the actual packet length after the to-be-scheduled packet is forwarded by a first network device, the second compensation value indicates an estimate of a variation relative to the actual packet length after the to-be-scheduled packet is forwarded by the receiver, and the first network device is a network device located between the packet compensation apparatus and the user equipment on a forwarding path of the to-be-scheduled packet;
• and
• determine a first packet length and a second packet length, wherein a value of the first packet length is equal to a sum of a value of the actual packet length and the first compensation value, and a value of the second packet length is equal to a sum of the value of the actual packet length and the second compensation value;
• and schedule the to-be-scheduled packet based on the first packet length and the second packet length,
• wherein the first network device is a network device that is based on an asynchronous transfer mode (ATM), and the first compensation value is equal to a length value of an ATM cell header times a quotient of the value of the actual packet length and a value of an ATM cell length.

A packet scheduling method, comprising:

• receiving, by an access device, a to-be-scheduled packet, wherein the to-be-scheduled packet is a packet sent by a network side to user equipment;
• obtaining, by the access device, an actual packet length of the to-be-scheduled packet, wherein the actual packet length indicates a total length of the to-be-scheduled packet;
• determining, by the access device, a first compensation value and a second compensation value based on the to-be-scheduled packet, wherein the first compensation value indicates an estimate of a variation relative to the actual packet length after the to-be-scheduled packet is forwarded by a first network device, the second compensation value indicates an estimate of a variation relative to the actual packet length after the to-be-scheduled packet is forwarded by the access device, and the first network device is a network device located between the access device and the user equipment on a forwarding path of the to-be-scheduled packet;
• determining, by the access device, a first packet length and a second packet length, wherein a value of the first packet length is equal to a sum of a value of the actual packet length and the first compensation value, and a value of the second packet length is equal to a sum of the value of the actual packet length and the second compensation value;
• and
• scheduling, by the access device, the to-be-scheduled packet based on the first packet length and the second packet length,
• wherein
• access bandwidth of the user equipment is total bandwidth accessed to the user equipment, the access bandwidth of the user equipment comprises first bandwidth, the first bandwidth is used to indicate bandwidth accessed to a target network service of the user equipment, a value of the first bandwidth is less than a value of the access bandwidth of the user equipment, and the method further comprises:
• determining, by the access device, an identifier of the user equipment, and determining a third compensation value based on the identifier of the user equipment, wherein the third compensation value indicates an estimate of a variation relative to the actual packet length after the to-be-scheduled packet is distributed by the user equipment to the target network service;
• and
• the scheduling, by the access device, the to-be-scheduled packet based on the first packet length and the second packet length specifically comprises:
• determining, by the access device, a third packet length based on the actual packet length and the third compensation value, wherein a value of the third packet length is equal to a sum of the value of the actual packet length and the third compensation value;
• and scheduling, by the access device, the to-be-scheduled packet based on the first packet length, the second packet length, and the third packet length.
