Switching system for inter-processor coupling device
专利汇可以提供Switching system for inter-processor coupling device专利检索，专利查询，专利分析的服务。并且PURPOSE: To continue the communication without being aware of a communication address change caused by switching by restoring PCI management information from drawback information at the time of integrating a PCI, and changing a fault PCI address of communication address information in the other PCI to a communication address of a stand-by PCI.
CONSTITUTION: Plural processors 2 - 4 are connected to a closed communication channel 1 of a ring shape or a bus shape through inter-processor coupling devices (PCI) 5 - 8, respectively, and in each PCI 5 - 8, mapping tables 9 - 12 in which a communication address and an entry number of the PCI 5 - 8 which become the other parties of communication are set, and a secondary medium for drawing back its information are provided. In such a state, when a communication by the existing PCI 5 is interrupted, mapping information 16 which is drawn back is reset to the mapping table 10 of the stand-by PCI 6, and a communication address is changed from the fault PCI 5 to the stand-by PCI 6, and informed to the other processors 3, 4 of communication. In such a way, even after the PCIs 5, 6 are switched, the communication can still be continued as it is.
