The present invention relates to physical address management of a local area network (LAN) of an intelligent network service control / management system, in particular, a multi-local area network (hereinafter simply referred to as a "LAN"), a high-speed communication environment consisting of multiple processors In addition, the present invention relates to a local area network (LAN) physical address management method of an intelligent network service control / management system for local area network (LAN) physical address management when using a lower protocol of the local area network (LAN) protocol for transmitting and receiving a large amount of messages.

In general, when sending a message on a LAN using a LAN subprotocol, the LAN physical address of the receiving processor should be given to the subprotocol along with the message to be transmitted. The LAN message transmission block uses this physical address for every message. Send a LAN message. At this time, when the LAN connection device of the receiving processor fails due to some reason and the device is replaced, the LAN physical address change of this processor occurs, and the LAN message transmission block returns to the previous LAN physical address of the receiving processor. There is no communication with this processor. Therefore, the LAN message transmission block must use the changed LAN physical address to communicate with the desired receiving processor. For this purpose, it is necessary to change the physical address without interrupting the service of the LAN message transmission block of each processor.

In the conventional case, when transmitting a message on a LAN, the LAN physical address contained in the program is used by the sending LAN message transmission block, or is read from an operator or a file.

It is a system that plays.

The input signal as the system is input from the input / output signal link through the CCS MTP Processor (CMP), which processes the lower part of the signal processing protocol, and the signal connection control and transaction processing in the Common Channel Processor (CCP), a front end processor connected to the VME bus. The SLP (Service Logic Processors 1 and 2), which are backend processors, generate a response message based on the service-specific logic data in the service processing memory database via the LAN devices LAN1 and LAN2, and convert the message into the reverse CCP. The data is sent to the service performing exchange via the CMP.

Here, the duplication of CCP, SLP, LAN, etc. is configured to have high performance and high reliability of this system, and CCP, SLP, LAN, which performs service under normal conditions, distributes the load half and half, and balances the load in the form of load sharing. For example, if one part becomes abnormal, the normal part is responsible for the load on the failed part. The service processing disk database is for backup and recovery of memory-resident databases that are maintained due to the characteristics that require real-time response, and the SMP (Service Management Processor) is provided for service data initialization and change management. I have a database.

The LAN physical address extraction block and the LAN physical address public memory loading block are provided in each processor including the OAP. The OAP has a task seat for management of LAN water fl addresses, and each processor, including the OAP, has an auxiliary storage device that maintains a LAN physical address table containing the LAN back address of all processors in the system. Each processor has two LAN connection devices, each having its own LAN physical address. The LAN physical address table recorded in the auxiliary memory is always kept unchanged while there is no change in the LAN interface physical address connected to this system, and the LAN message transmission block uses this physical address when restarting after the processor stops. Before starting the system, the OAP must collect the physical address of each processor's LAN access point and record the LAN logical address table in the OAP and each processor's auxiliary memory, which must be updated unless there is a change in the LAN access point. There is no. However, when there is a change in the LAN access point physical address, this table must be updated, and the table of each processor including the OAP must be updated to the same table. If this physical address is damaged, processors other than the OAP can be reloaded from the OAP.In the case of the OAP, the LAN physical address table of the OAP is updated by collecting all the processor's LAN physical addresses. You should update the LAN physical address table for all other processors.
