<p><P>PROBLEM TO BE SOLVED: To simultaneously measure an IP of a measuring target such as a router and layer-1 performance of a transmission system. <P>SOLUTION: The IP measuring device 21 comprises: an IP measuring module 22 which transmits a frame data signal 10 to a measuring target 8, receives a frame data signal 9 (9a) transmitted from the measuring target 8, and evaluates layer-2 or more performance of the measuring target 8 on the basis of frame data contained in the received frame data signal and the transmitted frame data signal 10; a layer-1 measuring module 23 which receives the frame data signal 9 transmitted from the measuring target 8 and evaluates layer-1 performance of the received frame data signal 9; and a display unit 30. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
