<p><P>PROBLEM TO BE SOLVED: To provide a network emulator device excellent in extensibility. <P>SOLUTION: An interface module 22 includes virtual nodes 27-1 to 27-N, and a traffic generator 24 transmits information about traffic virtually flowing through the virtual nodes 27-1 to 27-N through the virtual nodes 27-1 to 27-N to a network controller 13 in predetermined timing. The virtual nodes 27-1 to 27-N receive the request of path change transmitted from the network controller 13 and supply it to a resource simulator 23. The resource simulator 23 performs processing to the request of the path change, and transmits information indicating a processing result for the request through the virtual nodes 27-1 to 27-N to the network controller 13. This invention is applicable to a network emulator which tests the network controller, for instance. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
