Network monitoring device
First Claim
1. A network monitoring system having at least one monitoring device and a plurality of transmission devices connected to a network, said network monitoring system comprising:
- a first data storage unit, provided in said at least one monitoring device, which stores first status information of all of said transmission devices;
an information attaching unit, provided in said at least one monitoring device, which attaches abridged status information of at least one of said transmission devices to a polling command and sends said polling command to said at least one of said transmission devices, wherein said abridged status information is generated to reflect said first status information;
a second data storage unit, provided in each of said transmission devices, which stores second status information of a corresponding one of said transmission devices; and
a comparison unit, provided in each of said transmission devices, which checks if there is a mismatch between said abridged status information of a corresponding one of said transmission devices and said second status information.

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.

14. A monitoring device for monitoring a network to which a plurality of transmission devices are connected, said monitoring device comprising:
-
a data storage unit which stores status information of all of said transmission devices; an information attaching unit which attaches abridged status information of at least one of said transmission devices to a polling command, sends said polling command to said at least one of said transmission devices, and updates said status information based on a report sent from at least one of said transmission devices, wherein said abridged status information is generated to reflect said status information so that said at least one of said transmission devices can incorporate into said report information needed to update said status information, wherein said at least one of said transmission devices also checks to see if there is a mismatch between said abridged status information and second status information. - View Dependent Claims (23)
