Abstract
An internet protocol (IP) network device is provided including a detector adapted to detect an event in the internet protocol (IP) network device. The network device also includes a generator adapted to generate a trap message including event information having information about the detected event. The network device also includes a transmitter adapted to transmit, to an internet protocol (IP) network management device, the trap message including the event information and a first sequence indicator. The network device also includes a timer adapted to measure a time period from a time at which the transmitter transmits the trap information. If the measured time period is equal to or longer than a predetermined time, the generator generates an empty trap message and the transmitter transmits, to the network management device, the empty trap message and a second sequence indicator.
