Abstract
A transfer path in a router is set in a loop shape by a test processing unit. In a NP chip (network processor), decrement of a TTL value is inhibited by a test processing unit, and a routing table is set such that data are transmitted in order along the transfer path of the loop shape. Consequently, the test processing unit circulates a predetermined number of data on the transfer path of the loop shape, and inspects the data circulated.
