Abstract:
A fixed length data processing apparatus for processing fixed length data used for an asynchronous communication network, said fixed length data having transmission route identification information, said transmission route identification information being different depending upon a transmission route, said fixed length data processing apparatus comprising:a registration information holding unit for commonly holding for a plurality of transmission routes registration information necessary to identify fixed length data that is an object of a processing corresponding to a transmission route; and a data processing unit for identifying whether or not received fixed length data is fixed length data that is an object of a processing on the basis of at least said registration information in said registration information holding unit, to perform a data processing for fault management correspondingly to said transmission route, which data processing includes a process of generating alarm data to be notified to another fixed length data processing apparatus and inserting said alarm data to a flow of fixed length data passing through toward said another fixed length data processing apparatus, in said asynchronous communication network on the basis of said fixed length data when identifying that said fixed length data is fixed length data that is an object of a processing.
