Bufferless ring network

A bufferless ring network, comprising at least two nodes and at least two timeslots, wherein the at least two timeslots comprise a dedicated timeslot, wherein a first node in the bufferless ring network has use permission for the dedicated timeslot, wherein the first node is in a state of having the use permission for the dedicated timeslot, and wherein the first node is configured to:

• detect whether all dedicated timeslots that pass through the first node are available;
• set a permission switch signal when detecting that all the dedicated timeslots that pass through the first node are available;
• and
• cancel the use permission for the dedicated timeslot according to the permission switch signal,
• wherein a remaining node other than the first node in the bufferless ring network is configured to obtain the use permission for the dedicated timeslot according to the permission switch signal,
• wherein the remaining node comprises a node that needs to use the dedicated timeslot,
• wherein when obtaining the use permission, the remaining node is further configured to circularly shift a shift register corresponding to the remaining node by one bit in a preset direction when the remaining node detects the permission switch signal, and
• wherein a width of the shift register is equal to a quantity of nodes that need to use the dedicated timeslot in the bufferless ring network.
