Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] To achieve the purpose of the present invention, the present invention provides an all-optical FIFO shared buffer queue structure based on fiber delay lines, which will be described in detail below with reference to the accompanying drawings.
[0030] The optical network lacks the necessary optical cache to realize store-forward optical packet switching. The optical FIFO shared buffer queue structure of the present invention avoids the low-efficiency optical-electrical-optical conversion to realize optical packet storage. The timeline and optical switching matrix implement packet buffering. The optical fiber delay line mainly utilizes the delay characteristic of the optical signal when it propagates in the optical fiber, and uses different lengths of optical fiber as the medium to delay the input optical signal, thereby simulating the optical buffer function.
