Abstract

PURPOSE:To improve the strength of reception of burst message without reducing number of messages able to be received in a unit time when a time itself to store a received message to a database used by a job program having a retrieval key in the network management system is not decreased. CONSTITUTION:A message sent from an exchange enters a reception memory 12. A priority task 13 stores the reception message in the reception memory 12 to an FIFO form database 15. A task 14 started for a predetermined period reads the reception message from the database 15 and adds a retrieval key to the message and the resulting data are stored in a database 16. The priority task 13 attains its processing at a high speed independently of a time stored in the database 16, and a period task 14 attains storage processing without notifying trade-off of a processing time required to store the reception message in the reception memory 12 into the database 16 for the high speed requirement.

2. Description of the Related Art As shown in FIG. 2, a database creating method in a conventional network management system receives a message transmitted from an exchange 21 through a reception memory 22 in addition to an exchange 21 and a reception memory 22. It includes a priority task 23 for analyzing contents, adding a search key and storing it in a database 24, and a database 24 having a search key.

[0003]

In a network management system for managing a switching network including a plurality of exchanges,
The message sent from the exchange is very important for understanding the state of the exchange network. Further, since the exchanges are linked to each other, messages may be transmitted from each exchange in a burst depending on a failure.

In the conventional database creation method in the network management system, as shown in FIG. 2, the number of search keys used in the database 24 having the search key for storing the received message is increased so that the business program of the network management system can be easily used. When the database 24 is created, the data record storage processing time increases, and the number of messages received by the network management system per unit time and stored in the database 24 decreases. Therefore, when a message is sent in a burst from the exchange and the message is received by the network management system, the network management system is in a congestion state due to the resource reservation by the received message on the reception memory 24 waiting for the processing in the priority task 23. There was a problem that Further, there is a problem that the priority task 23 uses a lot of CPU time and the response of the work of the network management system becomes very slow.

The object of the present invention is to solve the above-mentioned problems,
Even if the number of search keys used in the database having the search key for storing the received message is increased, the network management system does not become congested, and the CPU usage time of the priority task is compressed to reduce the business response delay of the network management system. It is an object to provide a multi-stage base creation method of a received message in a network management system which can be significantly suppressed.

[0006]

According to the method of the present invention, a message transmitted from a plurality of exchanges constituting a switching network is received, the contents of the message are analyzed, a search key is added and stored in a database. A database creation method in a network management system, comprising: a first database having a pointer of a record to be written next and a pointer of a record to be read next, for writing and reading records by first-in / first-out; A priority task that receives a message and stores it in the first database, a second database that has a search key, a message that is activated in a predetermined cycle, reads the message from the first database, and analyzes the content to retrieve the search key. And a periodical task for storing it in the second database.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a multi-step database creation system for received messages in a network management system according to an embodiment of the present invention. This embodiment has an exchange 11, a reception memory 12 for storing a reception message from the exchange 11, a pointer of a record to be written next and a pointer of a record to be read next, and a first-in first-out (First-In). First-Out, hereinafter FI
A database 15 as a first database for writing and reading records by the FO method);
A priority task 13 for receiving a message from the exchange 11 via the reception memory 12 and storing it in the database 15.
And a database 16 as a second database having a search key, and a periodic task 14 for reading a message from the database 15, analyzing the content of the message, adding a search key, and storing it in the database 16.

Next, the operation of this embodiment will be described.
The message transmitted from the exchange 11 is stored in the reception memory 12 of the network management system. The priority task 13 is
The received message on the reception memory 12 is stored in the FIFO format database 15. The database 15 is composed only of the next write pointer, the next read pointer, and the record. Therefore, as shown in FIG. 4, the message storage processing time is, as shown in FIG. 4, the received message for the record pointed to by the next write pointer after the message is received (step S1). Writing (step S2) and updating the next write pointer (step S3) are performed only twice in the file server. Thus, the processing time of the reception message of the priority task 13 is executed at high speed without depending on the record storage time of the database 16 having the search key in the record of the reception message to be created next.

The task 14 activated in a predetermined cycle is shown in FIG.
As shown in, the received message is read from the record pointed to by the next read pointer of the database 15 (step S11), the content thereof is analyzed, and the search key is retrieved from the message issue time, station name, message class, message number, etc. in the exchange. Is created and set in a record together with the received message (steps S12, S13, S1
4 to S17), request the database management system (step S19), and the database 16 having the search key
To store.

In this way, the periodic task 14 responds to the request of the business program that uses the database 16 without paying attention to the trade-off with the high processing time for storing the received message in the receiving memory 12 in the database 16. The received message can be stored in the database 16 by adding a suitable search key.

In the above-mentioned embodiment, the combination of the periodic task and the database is single, but the timing of the periodic activation is adjusted in consideration of the contents of the target work, and the periodic task 14 and the database 16 and later are executed. Designing the combination of the database and the periodic task in multiple stages, to provide a gradual difference in processing between databases used for business programs that require real-time and those that do not,
The work response time can be optimized in the entire network management system.

[0012]

As described above, according to the present invention, a reception message is written by a priority task to a first database which has a next write pointer and a next read pointer and which writes and reads records by a FIFO, and activates at a predetermined cycle. The number of messages that can be received per unit time is reduced by reading the message written in the first database by the periodic task, analyzing the content, adding the search key and storing it in the second database that has the search key. Without receiving the burst message, the received message can be stored in the second database having the search key that meets the demand of the business program to be used while keeping the system resistant to receiving the burst message. Also, by considering the real-time nature of the work that uses the database and adjusting the timing of the periodical startup to design the periodical task, the database after the second database and the periodical task in multiple stages, The database used by the business programs required for the above is fast, and the database used by the business programs not requiring real time is slowly created, and the response time of each business can be made appropriate in the entire network management system.
