A method in which a network management system (NMS) processes information on a fault, such as numerous alarms or events, generated from high-capacity network equipment and forwards the processed fault information to a client in real-time. More particularly, the present invention relates to a fault information processing method and system for processing alarms more rapidly and efficiently using database table modeling to improve a delay in storing data in an alarm database in applications, which is most problematic in processing alarms and events. With the present invention, the temporary storage of the traps in the listener table is simply performed by the fault management module and other additional functions spending time are performed by adopting an asynchronous transaction processing manner through the listener daemon module in order to more rapidly and quickly process a large amount of alarm and event information which could not be satisfied in an existing synchronous manner, thereby realizing real-time processing of a number of traps.

In a method for the error-monitored transmission of data via interfaces of a multi-step communication system, the data is transmitted from a transmitter station to a data-receiving station via at least two relay stations which are connected therebetween and receive and further transmit the data parallel to each other. The data is retransmitted if the transmission has been insufficient due to a request from the receiver end and/or due to the lack of a confirmation from the receiver end. In order to increase performance while reducing power consumption of the system, the request or confirmation is generated only by the receiver station and is sent back to the transmitter station. The relay stations consequently do not generate any confirmations or requests.
