[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signal monitoring method for a network monitoring apparatus, and more particularly to a method for controlling a protocol conversion apparatus, receiving various network monitoring information signals from a communication network while performing protocol conversion, and editing network monitoring information. And a method for restricting the signal inflow of a network monitoring device that performs output.

2. Description of the Related Art A conventional network monitoring system is connected to various network monitoring controllers of a communication network, receives a network monitoring information signal according to various protocols, and converts it into a specific protocol. A network monitoring device connected via a communication line to receive network monitoring information on the signal of the specific protocol and store, edit, and display the network monitoring information. The network monitoring device includes a CPU and a memory, and controls each unit in the device based on a built-in program. A communication control unit operated by one application program uses one communication memory buffer. Communication processing with the protocol converter for the application program is collectively performed. In order to prevent the CPU (program execution right) from being occupied by some application programs, the conventional signal inflow regulation system includes processes such as taking a timing after each process in each application program is completed. The communication control unit monitors the usage rate of the communication memory buffer and restricts all communication when the usage rate exceeds a certain reference value.

[0003]

In the signal inflow control method of the conventional network monitoring apparatus, it is necessary to consciously create processing for avoiding CPU congestion in each application program. In addition, when the communication control unit imposes restrictions, all communications are regulated at once, and when urgent control of the protocol converter is desired (change of system configuration, change of connection with the communication network, etc.) Problem).

[0004]

According to the present invention, there is provided a signal monitoring system for a network monitoring device, comprising: a protocol conversion device for performing protocol conversion of various signals from a communication network; In a network monitoring system comprising a program-controlled network monitoring device that receives a signal and stores, edits, and outputs network monitoring information on the signal, the network monitoring device includes a first communication memory buffer, A communication control unit for controlling a protocol conversion device for transmitting and receiving signals for controlling the protocol conversion device to and from the protocol conversion device;
And a network monitoring communication control unit for transmitting and receiving a signal for monitoring the network of the communication network to and from the protocol conversion device, and using the second memory buffer for communication. In this configuration, the program execution processing of the network monitoring communication control unit is stopped for a certain period of time when the rate exceeds a predetermined reference value.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The network monitoring system according to the present embodiment includes a protocol conversion device 200 that converts a signal according to various protocols from a plurality of network monitoring information control units in the communication network 100 to a specific protocol, and the protocol conversion device 200 A network monitoring device 300 that receives a signal from the communication network 100 and accumulates and edits network monitoring information on the signal, and displays various information from the communication network 100, displays the status of the protocol conversion device 200, and inputs 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 of the program. The network monitoring communication control unit 400 includes a network monitoring communication control unit 400 and a protocol conversion device control unit. It has a communication control unit 410 and application processing units 500, 510, and 520 that perform various processes. Further, 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 fault information from the communication network 100 and display the processed information on the console 600, and control the system configuration of the duplicated protocol converter 200. Processing, communication network 100
, Respectively, to perform network monitor information content designation processing. Communication controller 410 for controlling protocol converter
Transmits and receives a control information signal 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.
00, a network monitoring information designation signal for the communication network 100 and a network monitoring information signal from the communication network 100 are transmitted and received. In general, the communication amount of the network monitoring communication control unit 400 is much larger than the communication amount of the protocol conversion device control communication control unit 410. Network monitoring communication control unit 400
Calculates the usage rate of the dedicated communication memory buffer 401 when a signal is received from the protocol conversion device 200, and if the value exceeds a certain reference value held as data, suspends processing for a certain period of time. 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, at the time of signal reception, the usage rate of the communication memory buffer 401 is obtained, and the restriction is applied based on the value.

As described above, it is possible to avoid exclusive use of the program execution operation of the CPU by the network monitoring communication control unit 400, and to control the protocol conversion device control communication control unit 410 and various application processing units 500 to 500 for controlling the protocol conversion device 200. 520 program execution time can be secured.

[0010]

As described above, according to the present invention, the communication control section in the program-controlled network monitoring device such as a CPU is divided into two, one for network monitoring and the other for protocol conversion device control. A buffer is provided, and the communication control unit for monitoring the network with a large communication volume monitors the usage rate of the communication memory buffer, and when it exceeds a certain reference value, suspends the processing for a predetermined time, thereby monitoring the network. This prevents the program execution operation in the CPU from being occupied by the processing for the purpose, and has an effect that the protocol converter can be controlled even when a load is imposed by the processing for network monitoring.
