Abstract
A network monitoring system having at least one monitoring device and a plurality of transmission devices connected to a network includes a first data storage unit, provided in the at least one monitoring device, which stores first status information of all of the transmission devices, and an information attaching unit, provided in the at least one monitoring device, which attaches abridged status information of at least one of the transmission devices to a polling command and sends the polling command to the at least one of the transmission devices, wherein the abridged status information is generated to reflect the first status information. The network monitoring system further includes a second data storage unit, provided in each of the transmission devices, which stores second status information of a corresponding one of the transmission devices, and a comparison unit, provided in each of the transmission devices, which checks if there is a mismatch between the abridged status information of a corresponding one of the transmission devices and the second status information.
