    • In order to reduce the required storage capacity as well as the processing time in a delay route searching technique for logical circuits, a fan-out direction delay time calculating means 22 figures out, for each component of a logical circuit, the worst transit time from the starting point; and a fan-in direction delay time calculating means 23 figures out, for each component of the logical circuit, the worst remaining time from that component to the end point. A delay analysis non-needing component identifying means 24 adds the corresponding pairs of the worst transit time and the worst remaining time calculated by the fan-out direction delay time calculating means 22 and the fan-in direction delay time calculating means 23 for each component, compares the resultant sums with the pertinent design standards on delay time, and thereby identifies components needing no delay analysis beyond which delay route search processing can be dispensed with, while the delay analysis non-needing component-reflecting delay route searching means 21 performs delay route searching covering no component beyond the components needing no delay analysis.

    • A router interposed between a subnet and a backbone network, where the subnet includes a plurality of layer 2 switches and a plurality of terminals. The terminals communicate with each other via the layer 2 switches and a master router, wherein the router connects to the master router, the subnet and the backbone network, and originally operates as a backup router, but can be transitioned to operate as a redundant master router. The router includes a severance detection unit for detecting severance between the layer 2 switches and a redundant function control unit which, when severance has been detected: (i) resumes interrupted communication between the backbone network and the subnet via the router, (ii) receives, from the master router, a copy of an address resolution protocol (ARP) table, and stores the copy of the ARP table in the router, and (iii) transitions the router into a redundant master router.
