PREFERRED EMBODIMENT OF THE INVENTION In the preferred embodiment of the network monitoring system of the present invention, monitoring equipment is connected by using TCP/IP with one dir more user devices, each of which has one or more control elements. The monitoring equipment transmits, by using the SOCKET communication, a request message which is received by the user device which executes the request and stores the execution resu It. When the user device completes the execution concerning all the control elements, it transmits, by using SOCKET communication, a response for notification 3 of completion of the execution toward the monitoring equipment which acquires, by using FTP command, the execution result stored in a memory of the user In the present 'invention, a file including contents of the control request may be transferred by.FTP command from the monitoring equipment to the user device. In this case, after the transfer of the file, a control request is transmitted by the SOCKET communication from the monitoring equipment to the user device which executes the request on the.basis of the contents of the file, and transmits a response message with the execution result by using the SOCKET communication.
An example of a network monitoring system of the present invention is shown in Figure 1, wherein monitoring equipment 10 is connected with user device 20 through a network. Monitoring equipment 10 comprises processing unit 13, memory 11, and protocol termination unit 12, while user device 20 comprises processing unit 23, control elements 301 to 30n) memory 21, and protocol termination unit 22. In this network, the request message and response message are transmitted by SOCKET and TCP/IP (transmission control protocollinternet protocol), while files are transported by FTP (file transport protocol)which is defined by WC 959 (Request For Comments by IETF (Internet Engineering Task Force)).
User device 20 collects control information of control elements 30, to 30. . Then, it transmits the control information to monitoring equipment 20, or stores the control information in memory 21.
4 a Monitoring equipment 10 transmits, by using SOCKET, a request message for: instructing the user device to execute control procedures for control elements 30, to 30n- User device 20 executes the control procedures on the basis of the request message, and stores the execution results as a file in memory 21. Further, user device 20 transmits a response message by using SOCKET in order to notify monitoring equipment of a completion of the control procedures.
Monitoring equipment 10 takes in the file stored in memory 2 1, by using the FTP command, and stores the file in memory 11. Thus, monitoring equipment 10 acquires the execution result in user device 20.
A detailed block diagram of the network monitoring system of the present invention is shown in Figure 2. User device 10 maybe slave equipment which comprises modems 31, to 31, The set of modems 31, to 31,, are assembled modems, or a modem pool. Modems 31, to 31n are connected with subscriber modems 50, to 50,, through subscriber lines 40, to 40n- Modem speed is optimized by connection training. It a much longer time, in proportion to the modem speed, to complete the connection training.
Several items such as performance monitoring are decided according to the protocol actually installed, for monitoring continuously the connection states of the modems for the purpose of prevention and maintainance.
Hub/Multiplexer 24 may or may not be installed, depending upon the system construction. Further monitoring equipment 10 may be switching equipment. A first example of control sequence is shown in Figure 3. 5 At SOCKET communication sequence 100, request message 101 is transmitted from processing unit 13 of monitoring equipment 10 through protocol termination unit 12 to user device 20, by using SOCKET-TCP/IP Request message 101 may request, for example, to collect the performance monitoring of all the control elements in user device 20. Then, monitoring equipment 10 awaits a response from user device 20.
in particular, monitoring equipment 10 monitors a reception of the response message at message read-in sequence 110 and at reception 111. In particular, an inspection is made to see whether or not the message received is a response message on the basis of interrupt notification, at reception check sequence 111.
When user device 20 receives request message 101 at SOCKET communication sequence 100, it collects performance monitoring information from all control element 1 to N at processing sequence 210, stores the processing result in memory 21 as file 220, and finally transmits response message 102for indication a completion of processing- toward monitoring equipment 10 at SOCKET communication sequence 110.
When monitoring equipment 10 receives response message 102, it exits from the response waiting to start communicating with user device 20 with a FTP communication sequence. In particular after remove log-in into user device 20 at sequence 201, monitoring equipment 10 requests transfer of file 220, made by user device 20, by using the "geC command of the FTP. Then, in response to the request, user device 20 transmits file 220 to monitoring equipment 10.
6 Monitoring equipment 10 stores file 220 as file 120 in memory 11.
When a plurality of user devices are connected with a single monitoring equipment, identical control requests are issued by the SOCKET to all the user devices. Afterwards, files from the user devices are collected by the FTP, because the FTP communication is independent of the SOCKET communication.
A second example of control sequence for the network monitoring system is shown in Figure 4. The monitoring equipment 10 makes beforehand file 120 in memory 11 concerning modem set-up and control information for user device 20. Then, monitoring equipment 10 executes the FTP communication at sequence 200, executes remote log-in into user device 20 at sequence 201, requests to transfer file 120 toward user device 20 by using a "puC 202, and finally sends file 120. User device 20 receives file 120 at sequence 203.
User device 20 stores file 120 as file 2 20 in memory 2 1.
After sending file 120, monitoring equipment 10 sends request message 101 which contains set-up conditions and control information for the control elements, by using the SOCKET communication.
Then, monitoring equipment executes a loop processing of sequences 110 and 111for receiving a response from user device 20.
When user device 20 receives request message 101, it executes the request concerning control elements 1 to N on the basis of request message 101 and file 220.
7 from adder 002 are modulated by modulator 003.
Here, execution time required for training sequence for the modem should be assured.
After completing the requested processing, user device 20 sends response message 102 for notification of completion of execution of the request.
User device 20 inserts a flag or identifier which indicates the execution result in response message 102,thereby notifying monitoring equipment 10 of an exceptional result, such as a failure in requested set-up or control.
When all the control elements need to be monitored in the.. conventional network monitoring system, the SOCKET communication must be executed for each control element.
However, according to the first example of the control sequence of network monitoring system of the present invention, only three communication procedures, that is, one SOCKET transmission, one SOCKET reception, and one FTP transfer are required, even when a plurality of control elements are included in user device 20. Thus, network communication is controlled easily,_network traffic is reduced, and the network is utilized efficiently.
Further, when a part of control elements should be monitored in the conventional network monitoring system, the SOCKET communication must be executed for that part of control elements one by one.
However, according to the second example of the control sequence of network monitoring system of the present invention, the above-mentioned one by one communication becomes unnecessary. In this case, too, only three 8 communication procedures, that is, one SOCKET transmission, one SOCKET reception, and FTP transfer are required, even when a plurality of control elements are included in user device 20. Thus, network communication is controlled easily. Further, it becomes unnecessary to manage transitions of state of lower protocol layers in the user device. Therefore, control load on the monitoring equipment is reduced.
While the present invention has been described in its preferred embodiments, it is to be understood A network monitoring method for reducing the traffic in the network, thereby operating the network efficiently and improving the throughput. In the network monitoring system of the present invention, wherein monitoring equipment is connected through a network with a user device with one or more control elements, the monitoring equipment transmits a request message which is received by the user device, which executes the request and stores the execution result.
When the user device completes the execution concerning all the control elements, it transmits a response for notification of the completion of the execution toward the monitoring equipment with acquires the execution result by using the FTP used in the TCPAP.
