摘要： 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.

摘要： An internet protocol (IP) layer processor has an IP header processing section for checking a defect in an IP header of a first ATM cell of an AAL5 frame, and a SAR (segregation and reassemblage) section for transferring the AAL5 frame in the form of separate ATM cells if the check by the IP header processing section indicates a normal IP header, without using a CPU. SAR notifies a defect in the IP header to CPU without transmission of the AAL5 frame if the check indicates the defect in the IP header. The IP layer processor achieves a higher processing due to the direct transfer by the SAR without using processing by a software.
