Electric system information state service system and core switch

The invention discloses an electric system information state service system. A cluster system is connected with a core switch and connected with multiple network switches. The core switch comprises a data interface recognition module, an interrupt recognition module, a nonvolatile storage and a remote control module, wherein the data interface recognition module is used for recognizing categories of application interfaces from at least one application server so as to further connect and control applications; the interrupt recognition module is used for having random access to any application server in the cluster system through the network switches, recognizing an application server having a linkage fault and obtaining specific information of the faulted application server; the nonvolatile storage is used for receiving and storing the category of the recognized application interface and storing the specific information of the faulted application server so as to associate the special information; the remote control module is used for searching for another application server adjacent to the faulted application server according to associated information, controlling the data interface reorganization module to be connected with the interface of the another application server according to the category of the interface of the another application server, and conducting transmission for the applications again. The invention further discloses the core switch in the server cluster system.
