Abstract: A scheduling method for switching including receiving an allocation request for a time slot from input nodes to which the time slot is not allocated, receiving property information of at least one of virtual output queues (VOQs) in which data received by the input nodes is stored, determining a transmission priority of the VOQs for transmission of the data stored in the VOQs based on the received property information of the VOQs, determining input nodes to which the time slot is to be allocated using outputter arbiters for output nodes corresponding to the VOQs, allocating the time slot to the determined input nodes, and updating elements used to allocate the time slot with respect to input nodes for which the allocating of the time slot is completed and output nodes for which the allocating of the time slot is completed.

Abstract: A system for cooperation of disaggregated computing resources interconnected through an optical circuit, and a method for cooperation of disaggregated resources are disclosed. Functional block devices such as a processor block, an accelerator block, and a memory fabric block exist at a remote location, and these three types of remote functional block devices are interconnected and interoperated in a specific program to perform a cooperative computation and processing process. Accordingly, the system shares data and information of a memory existing in each block through optical signal interconnection that provides low-latency, fast processing, and wide bandwidth, and maintains cooperation and memory coherency.
