Title:
SERVICE RECOVERY METHOD, DATA PROCESSING UNIT AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/109880
Kind Code:
A1
Abstract:
The present application provides a service recovery method. The method is executed by a DPU interface card, and specifically, after software (e.g. an operating system, another application program, etc.) of the DPU interface card is restarted, the DPU interface card acquires service information stored in a memory of a host, wherein the service information is information generated when the DPU interface card processes, before the software is restarted, an IO sent by a processor of the host, such that the DPU interface card recovers a service according to the service information stored in the memory of the host. Therefore, a DPU interface card does not need to depend on a local memory to recover an interrupted service, such that even if service data of a service is lost due to a version upgrade of software (e.g. an operating system, etc.) of the DPU interface card, a memory fault of the DPU interface card or other reasons, the DPU interface card can also quickly recover the service by using a memory of a host, thereby reducing the impact on the service.
