Abstract: A photonic frame switching system may include a main controller and at least one photonic frame wrapper line card. The main controller may determine a point in time at which a photonic frame wrapper line card transmits a photonic frame by allocating a time slot to the photonic frame wrapper line card. When the photonic frame switching system includes a plurality of photonic frame wrapper line cards, points in times at which the plurality of photonic frame wrapper line cards transmits the photonic frames may be synchronized. In particular, when a portion of the plurality of photonic frame wrapper line cards transmit a plurality of photonic frames having different destinations, points in times at to which all of the plurality of photonic frame wrapper line cards transmits the photonic frames may be adjusted based on a latency by a destination change.

Abstract: A photonic frame switching method and system. The photonic frame switching method includes resetting, by a second input module receiving a master notification, a second timeslot counter used in the second input module to be synchronized with a first timeslot counter used in a first input module, and transmitting a photonic frame from each of a plurality of input modules to a photonic switch fabric device according to a timeslot allocated to each of the input modules based on a scheduling acknowledgement signal transmitted from a main controller, based on the synchronized first and second timeslot counters.
