System and method for photonic switching

摘要

In one embodiment, a method of photonic frame scheduling includes receiving, by a photonic switching fabric from a top of rack (TOR) switch, a frame request requesting a time slot for switching an optical frame to an output port of a photonic switch of the photonic switching fabric and determining whether the output port of the photonic switch is available during the time slot, and generating a contention signal including a grant or a rejection, in accordance with the determining. Also, the method includes assigning the time slot to the TOR switch for the output port of the photonic switch, when the contention signal includes the grant, transmitting, by the photonic switching fabric to the TOR switch, the contention signal and receiving, by the photonic switching fabric from the TOR switch, the optical frame during the time slot, when the contention signal includes the grant.

1. A method of photonic frame scheduling, the method comprising:
receiving, by a photonic switching fabric from a first top of rack (TOR) switch, a first frame request requesting a first time slot for switching a first optical frame to a first output port of a photonic switch of the photonic switching fabric; determining whether the first output port of the photonic switch is available during the first time slot; generating a first contention signal comprising a grant or a rejection based on whether the first output port of the photonic switch is available during the first time slot; assigning the first time slot to the first TOR switch for the first output port of the photonic switch when the first contention signal comprises the grant; transmitting, by the photonic switching fabric to the first TOR switch, the first contention signal; and receiving, by the photonic switching fabric from the first TOR switch, the first optical frame during the first time slot, when the first contention signal comprises the grant.
