摘要： Method for complex coloring based parallel scheduling for the switching network that is directed at traffic scheduling in the large scale high speed switching network. The parallel scheduling algorithm is on a frame basis. By introducing the concept of complex coloring which is optimal and can be implemented in a distributed and parallel manner, the algorithm can obtain an optimal scheduling scheme without knowledge of the global information of the switching system, so as to maximize bandwidth utilization of the switching system to achieve a nearly 100% throughput. The algorithm complexity is O(log2 N).

摘要： An arrayed waveguide grating (AWG) based multi-core and multi-wavelength interconnection network, comprising N upper-level switches, N lower-level switches, and a network intermediate stage, with each upper- and lower-level switches has N CWDM optical transceiving modules. The N optical transceiving modules of each upper-level switch is connected with n m×1 multi-core optical multiplexing modules, the N optical transceiving modules of each lower-level switch is connected with n 1×m multi-core demultiplexing modules, the network intermediate stage is comprised of n2 r×r multi-core and multi-wavelength wiring modules. The upper-level multi-core optical multiplexing modules, the lower-level multi-core demultiplexing modules, and the n2 r×r multi-core and multi-wavelength wiring modules of the network intermediate stage are connected via an m-core MPO-MPO optical fiber jumper. The wiring complexity of the interconnection network is O(N2/r), with employment of a wavelength set of Λ={λ0, . . . , λk-1}. The present invention conserves wavelength resources of communication windows, enhances scalability of the AWG based interconnection network, while reduces network wiring complexity.

摘要： A method for constructing an AWG based non-blocking optical multicast switching network, comprising constructing a non-blocking optical copy network via a wavelength replication module and an arrayed waveguide grating recursively and constructing a non-blocking optical multicast switching network via cascading a data copy network with a point-to-point switching network. The number of active optical devices required for constructing an N×N optical switching network with r input/output ports and with each port carrying m wavelengths is just O(N logm N), realizing system scalability and saving hardware cost and power consumption. By splitting the routing path of the multicast network into a routing path with O(1) complexity in the copy network and a routing path in a point-to-point unicast switching network, the routing complexity of the multicast switching network is equivalent to that of a unicast switching network.

摘要： The present invention discloses a frequency domain equalization method, including transmitting an optical signal transmitted over a long distance to a dispersion compensation device, and performing dispersion compensation and equalization processing on the optical signal through the dispersion compensation device. The present invention utilizes the compensation effect of a single dispersion compensation device to realize dispersion compensation and frequency equalization on the optical signal, reducing the bandwidth requirements for the devices at the emitting and receiving ends, allows the directly modulated laser to still support long-distance fiber transmission in the case of high-speed signal modulation, and greatly reduces the system cost. In addition, transmissions over different distances can be supported by changing the value for the dispersion amount, so that the distance can be adjusted flexibly according to the requirements in the data center or other application scenarios.
