Abstract
A switch is provided that implements flexible switch scheduling according to priority levels set in data, by means of a simple apparatus configuration. A scheduler provided in the switch includes a request distribution block that distributes transfer data connection requests according to the priority level of the transfer data, a first allocator that performs allocation for high-priority-level transfer data connection requests from among the distributed connection requests, a second allocator that performs allocation for low-priority-level transfer data connection requests, an allocation combination block that combines the results of allocation by the first and second allocators, and a grant generator that sets a switch execution block on the basis of the combined allocation result, and outputs Grant signals; and further includes a request mask block that masks connection requests that duplicate the result of allocation by the first allocator before allocation is executed by the second allocator.
