PHOTONIC FRAME SWITCHING SYSTEM DETERMINING MOMENT OF TRANSMITTING PHOTONIC FRAME BASED ON TIME USED FOR CHANGING WAVELENGTH OF TUNABLE LASER DIODE

摘要

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.
