Abstract:
1. A communication apparatus for monitoring a network system in which a frame is transferred by a maintenance frame for maintenance and management, the apparatus comprising: an input-output section which inputs or outputs a frame; a failure detection section which detects occurrence of a failure in the network system on the basis of the frame inputted from the input-output section; a setting section which sets the communication apparatus on the basis of detection of the occurrence of the failure by the failure detection section so as to terminate or transfer a data frame, wherein the terminate is MEP (Maintenance Entry Point) and the transfer is MIP (Maintenance Intermediate Point); a data frame control section which exercises control on the basis of setting regarding the data frame of the communication apparatus by the setting section so as to terminate or transfer the data frame inputted from the input-output section; and a maintenance frame control section which exercises control on the basis of the setting regarding the data frame by the setting section so as to terminate or transfer the maintenance frame inputted from the input-output section; wherein the setting section changes a frame transferring function of the communication apparatus from the MIP to the MEP and sets the communication apparatus to a monitoring termination node, when a blocking point of the frame is set in the communication apparatus; and wherein the setting section changes a frame transferring function of the communication apparatus from the MEP to the MIP and sets the communication apparatus to a monitoring intermediate node, when the blocking point of the communication apparatus is released.
