The present invention relates to an apparatus and method for multiplexing operations, and more particularly, to multiplexing using distributed processing.

In general, a system providing a multiplexing protection switching is composed of a plurality of boards (Board) to provide a real service and a board for fewer protection switching than the plurality of boards.

If a failure occurs in the service providing board in such a system, the protection switching board performs the service instead.

In the above case, the protection switching boards have the same setting information of each board for fast switching when providing a real-time service such as a voice call, and a function that needs to provide a service that is provided as soon as possible when performing the switching is necessary. Do.

The performance of the board in charge of the protection switching is required to have a relatively superior board to cope with a plurality of service providing board. In general, however, a board with the same performance as a service board is used.

In addition, if the protection transfer board is not set in advance for protection transfer, it is not possible to predict which board to replace during the transfer request, and thus hardware setting cannot be performed in advance.

When the protection switching service starts for the same reason as above, there is a problem in that it takes a lot of time to transfer since the setting of the board in charge of the protection switching starts.

1 illustrates a 3: 1 switching service, and the master board 150 provides setting information such as call setup information to the service providing board 160, and a protection switching board when a switching event occurs. Allow 170 to take over the service.

The service providing board 160 provides an actual service and transfers the setting information received from the master board 150 to the protection switching board 170.

The protection switching board 170 receives setting information from the service providing board 160 and replaces the service providing board 160 when a switching event occurs.

When the master board 150 requests call setup from the service providing board 160 in step 110 of FIG. 1A, the service providing board 160 performs call setup and protects in 120 of FIG. 1A. The setting information is transmitted to the protection switching board 170 for the switching function.

Thereafter, as in step 130 of FIG. 1B), when the transfer event occurs and the service being provided is transferred to the protection switching board, the protection switching board 170 identifies the service providing board in which the switching event occurs, and then the switching event. On the basis of the setting information of the board on which the service has occurred, the service providing board on which the transfer event has occurred continues to be provided.

In step 140 of FIG. 1B), the protection switching board 170 receives the setting information from the master board 150. That is, the process of performing the function that the service providing board 160 was performing instead.

However, in the above process, relatively high performance is required for the protection switching board 170 to cover a plurality of service providing boards 160, and the protection switching board 170 sets information on the board where the switching event occurs. After going through the setting process based on the, there is a problem that takes a lot of time since the service provided by the service providing board in which the transfer event has occurred to continue to perform.

The apparatus of the present invention for solving the above problems is in the apparatus for multiplexing operation using distributed processing, when the transfer event occurs, the transfer of the service providing board to the other service providing board other than the transfer service providing board performs It includes a master board for instructing to perform a function, and a service providing board for dividing and processing a function that can not be performed by switching when the transfer event occurs.

 The method of the present invention for solving the above problems is a method of a master board for multiplexing operation using distributed processing, when each service providing board attempts to store the setting information in a shared folder, the setting information is stored. When the transfer event occurs after the storing process, the service providing board divides the service provided by the service providing board having the transfer to the other service providing board except the service providing board where the switching has occurred. It characterized in that it comprises a step of providing instructions.

Another method of the present invention for solving the above problems is a method of a service providing board for multiplexing operation using distributed processing, the process of setting the service providing board by analyzing the setting information requested by the master board, and the setting process Thereafter, the setting information is stored in the shared folder of the master board, and after the storing process in the shared folder, the information set by the other service providing board when the master board requests setting from another service providing board. Loading from the shared folder of the master board and storing in the extra area of the service providing board, storing the extra area in the extra area, and when a transfer event occurs, Setting of the transferred service providing board stored in the extra area based on the information Using the information characterized by comprising the step of the service provider switching a board is provided, and provided by dividing a service that has occurred.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
