In the signal inflow regulation system of this conventional network monitoring device, it is necessary to intentionally incorporate processing for avoiding congestion of the CPU in each application program. In addition, when the communication control unit is regulated, all communications are collectively regulated, and when you want to control the protocol conversion device urgently (such as changing the system configuration or changing the connection with the communication network, There was a problem that it interfered.

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The network monitoring system of the present embodiment includes a protocol conversion device 200 for converting signals from a plurality of network monitoring information control means in the communication network 100 into a specific protocol by various protocols, and via the protocol conversion device 200. For receiving a signal from the communication network 100, storing and editing network monitoring information on the signal, for displaying various information from the communication network 100, for displaying the status of the protocol conversion device 200, and for inputting control commands. Console 600.

The network monitoring device 300 is mainly composed of a memory containing a program such as an OS and various applications and a CPU for controlling the operation by this program. The network monitoring communication control unit 400 and the protocol conversion device control device are used. It has a communication control unit 410 and application processing units 500, 510 and 520 that perform various processes. The network monitoring communication control unit 400 and the protocol conversion device control unit communication control unit 410 have dedicated communication memory buffers 401 and 411, respectively.

Next, the operation will be described. The application processing units 500 to 520 process and edit network monitoring information such as traffic information and failure information from the communication network 100 and display it on the console 600. Control of the system configuration of the duplex protocol conversion apparatus 200. Processing, communication network 100
The content specification processing of the network monitoring information for each is shared and performed. Communication control unit 410 for controlling protocol conversion device
Transmits and receives control information signals of the protocol conversion device 200 under the control of the application processing units 500 to 520. The network monitoring communication control unit 400 controls the protocol conversion device 2 under the control of the application processing units 500 to 520.
Via 00, a designation information signal of network monitoring information for the communication network 100 and a network monitoring information signal from the communication network 100 are transmitted and received. The communication traffic of the network monitoring communication control unit 400 is usually much larger than the communication traffic of the protocol conversion device controlling communication control unit 410. Network monitoring communication control unit 400
Determines the usage rate of the dedicated communication memory buffer 401 when a signal is received from the protocol conversion device 200, and suspends processing for a certain period of time when the value exceeds a certain reference value held as data. Regulates the inflow of the next signal. After a certain period of time, the reception processing of the next signal is restarted, and thereafter, similarly, when the signal is received, the usage rate of the communication memory buffer 401 is obtained, and the regulation is applied according to the value.
