Abstract:
1. A network information analyzing method for determining a status of a network including a plurality of communication apparatuses, the method comprising: registering line management code information in a management apparatus, the line management code information including a line identifier identifying each of the plural communication apparatuses in correspondence with each logical line; assigning the line identifier to each logical line used for establishing data communication between a transmission terminal and a reception terminal within the network; transmitting from the management apparatus to the communication apparatuses the line management code information including the line identifier; controlling each communication apparatus receiving the line management code information to output the received line management code information to the logical line identified by the line identifier included in the received line management code information; controlling each communication apparatus to extract the line management code information from a transmission signal, attach a corresponding apparatus identifier assigned to the communication apparatus to the extracted line management code information, and transmit the extracted line management code information attached with the corresponding apparatus identifier to the management apparatus; and analyzing the status of the network and determining a communication apparatus of an error occurring location and a channel of the error occurring location at the management apparatus based on the extracted line management code information attached with the corresponding apparatus identifier received from each communication apparatus; wherein the registering of the line management code information is performed before the transmitting of the line management code information; wherein the line management code information includes at least one of an apparatus identifier assigned to each communication apparatus, a line direction code corresponding to the line identifier, and data amount corresponding to the line identifier.
