WIPO Patent Application WO/2019/149031
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data processing method and apparatus applied to a node system. The method comprises: a first node controller receives a data access request sent by a first node, and determines that first data is not managed by the first node controller; the first node controller sends a listening request to processors of all the nodes connected to a second node; the first node controller receives a listening response, with regard to the first data, sent by a first target processor, the first target processor being the processor, in the processors of all the nodes connected to the second node, caching the first data; and the first node controller obtains, according to the state of the first data in the listening response, the first data and sends the first data to the first node. According to the present solution, when a fault occurs to a second node controller, by transferring a service to a first node controller on another NC plane for processing, and carrying out broadcast listening, the system can still process data normally without going down.
