Patent ID: 8014297

Claim:
A network test apparatus connected to a relay apparatus, comprising: a transmitting/receiving unit transmitting/receiving to/from a relay apparatus an OAM frame containing one or more kinds of tests to test Ethernet-OAM conformance of the relay apparatus; a configuration information storage unit storing configuration information to generate, in a pseudo manner, a pseudo network configuration needed for each of the kinds of tests; a kind distinguishing unit, distinguishing a kind of test contained in the OAM frame and obtaining network information of a network to which the relay apparatus that transmitted the OAM frame belongs, when the OAM frame is received from the relay apparatus; a test conducting unit generating, in a pseudo manner, a pseudo network configuration including a pseudo network and/or a pseudo network apparatus according to the OAM frame received from the relay apparatus and conducting a test for Ethernet-OAM conformance of the relay apparatus on the generated pseudo network configuration corresponding to the kind of test, based upon the configuration information corresponding to the kind of test; and a test result storing unit storing a result of the test conducted by the test conducting unit.
