Setting device, parameter setting method, and storage medium storing program

A parameter setting method to set a parameter for transmission queues at an Ethernet switch, the parameter setting method comprising:

• performing assignment processing to assign associations between an attribute associated with a transmission frame and a plurality of the queues having different priorities;
• performing a first setting processing to set a first parameter for a high priority queue of the plurality of queues having a priority equal to or higher than a threshold based on an adverse condition transmission schedule having transmission timings less desirable than transmission timings of a preset transmission schedule, the first parameter including a band corresponding to the high priority queue and a necessary buffer size for packet transmission;
• performing a second setting processing to set a second parameter for a low priority queue having a priority of less than the threshold using processing that is different from the first setting processing;
• and
• setting the band and the necessary buffer size to a band and a buffer size for which communication delay is resolvable when the packet transmission is performed according to the adverse condition transmission schedule.

A non-transitory computer readable storage medium storing a program executable by a computer to perform processing to set a parameter for transmission queues at an Ethernet switch, the processing comprising:

• assignment processing to assign associations between an attribute associated with a transmission frame and a plurality of the queues having different priorities;
• first setting processing to set a first parameter for a high priority queue of the plurality of queues having a priority equal to or higher than a threshold based on an adverse condition transmission schedule having transmission timings less desirable than transmission timings of a preset transmission schedule, the first parameter including a band corresponding to the high priority queue and a necessary buffer size for packet transmission;
• second setting processing to set a second parameter for a low priority queue having a priority of less than the threshold using processing that is different from the first setting processing;
• and
• third setting processing to set the band and the necessary buffer size to a band and a buffer size for which communication delay is resolvable when the packet transmission is performed according to the adverse condition transmission schedule.
