Abstract:
1. A network failure information collection apparatus to collect information about network failure in a network communication apparatus connected to a packet network, comprising: a normal mode packet assembly unit to assemble a transmission packet from transmission data output from an application in a normal mode being a procedure used when a transmission process is performed by specified communication protocol and to transmit the transmission packet to the packet network; a special mode packet assembly unit to assemble the transmission packet from the transmission data in a special mode being a procedure in which a procedure for collecting failure information is embedded into the procedure used when a transmission process is performed by the specified communication protocol and to transmit the transmission packet to the packet network; a switching control unit to activate the normal mode packet assembly unit or the special mode packet assembly unit selectively; a response analysis unit to analyze a response to the transmission packet based on a received packet from the packet network and to collect failure information according to a behavior of the response to the transmission packet transmitted from the special mode packet assembly unit; and an output unit to output the failure information.
