Control method, communication method, controller, node device, and readable medium

A controller, comprising:

• one or more processors;
• and
• a storage device having stored thereon one or more programs which, when executed by the one or more processors, cause the one or more processors to implement a control method comprising:
• configuring and issuing a time gate control list;
• wherein the time gate control list comprises at least one deterministic queue and a plurality of time slices;
• and in each deterministic queue, a gate corresponding to a periodic time slice of the deterministic queue is open, gates corresponding to periodic time slices of other deterministic queues are closed, and a gate corresponding to a free time slice is open, with the periodic time slice of the deterministic queue being a time slice corresponding to a time when data packets of a deterministic service flow are periodically forwarded in the deterministic queue, and the free time slice being a time slice other than the periodic time slice of each deterministic queue.
