摘要
A node device in an ATM communication network is provided which is capable of generating a cell for creating a failure alarm rapidly so as not to apply a load to a processor. The node device copies header data from an ATM cell, and uses the copied header data to generate a failure alarm cell (e.g., an Alarm Indication Signal (AIS)). The node device obtains a VPI (Virtual Path Identifier) or VPI/VCI (VPI/Virtual Connection Identifier) for the failure alarm notification cell from a header of the cell on the VP (Virtual Path) which forms the pair of the failed VP. Accordingly, the processor does not need to process data from a header conversion table.
