Mapping multiplexing method and apparatus for optical transport network, and electronic device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the memory stores an instruction executable by the at least one processor, and the at least one processor is configured to run the instruction to execute the following operations:
• first providing a mapping opportunity generated by an Optical Channel Payload Unit (OPU) in a current transport window to one or more Optical Service Unit (OSU) services, which satisfy a first scheduling condition, in a first queue, and performing in-queue scheduling on the one or more OSU services, which satisfy the first scheduling condition, in the first queue so as to provide the mapping opportunity to one of the one or more OSU services in the first queue, wherein the first scheduling condition comprises:
• there is an OSU frame to be sent, or the remaining service mapping opportunity quantity reaches a preset upper limit M_max of the remaining service mapping opportunity quantity;
• and the second scheduling condition comprises:
• there is an OSU frame to be sent, and the remaining service mapping opportunity quantity is larger than a preset lower limit M_min of the remaining service mapping opportunity quantity;
• wherein the upper limit M_max and the lower limit M_min of respective OSU service are independently set;
• in a case where there is no OSU service satisfying the first scheduling condition in the first queue, providing the mapping opportunity to one or more OSU services, which satisfy a second scheduling condition, in a second queue, and performing in-queue scheduling on the one or more OSU services, which satisfy the second scheduling condition, in the second queue so as to provide the mapping opportunity to one of the one or more OSU services in the second queue;
• updating a remaining service mapping opportunity quantity of the OSU service which gets the mapping opportunity, wherein a service mapping opportunity quantity of respective OSU service in one transport window is independently set;
• and
• dynamically allocating OSU services entering mapping and multiplexing in the current transport window to the first queue and the second queue according to the remaining service mapping opportunity quantity of respective OSU service, wherein the remaining service mapping opportunity quantity of the OSU service assigned to the first queue is greater than the remaining service mapping opportunity quantity of the OSU service assigned to the second queue.

A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program, when being executed by a processor, causes the processor to execute the following operations:

• first providing a mapping opportunity generated by an Optical Channel Payload Unit (OPU) in a current transport window to one or more Optical Service Unit (OSU) services, which satisfy a first scheduling condition, in a first queue, and performing in-queue scheduling on the one or more OSU services, which satisfy the first scheduling condition, in the first queue so as to provide the mapping opportunity to one of the one or more OSU services in the first queue, wherein the first scheduling condition comprises:
• there is an OSU frame to be sent, or the remaining service mapping opportunity quantity reaches a preset upper limit M_max of the remaining service mapping opportunity quantity;
• and the second scheduling condition comprises:
• there is an OSU frame to be sent, and the remaining service mapping opportunity quantity is larger than a preset lower limit M_min of the remaining service mapping opportunity quantity;
• wherein the upper limit M_max and the lower limit M_min of respective OSU service are independently set;
• in a case where there is no OSU service satisfying the first scheduling condition in the first queue, providing the mapping opportunity to one or more OSU services, which satisfy a second scheduling condition, in a second queue, and performing in-queue scheduling on the one or more OSU services, which satisfy the second scheduling condition, in the second queue so as to provide the mapping opportunity to one of the one or more OSU services in the second queue;
• updating a remaining service mapping opportunity quantity of the OSU service which gets the mapping opportunity, wherein a service mapping opportunity quantity of respective OSU service in one transport window is independently set;
• and
• dynamically allocating OSU services entering mapping and multiplexing in the current transport window to the first queue and the second queue according to the remaining service mapping opportunity quantity of respective OSU service, wherein the remaining service mapping opportunity quantity of the OSU service assigned to the first queue is greater than the remaining service mapping opportunity quantity of the OSU service assigned to the second queue.
