Data transmission method, device, equipment, medium and product

The invention relates to the technical field of remote direct data access, and discloses a data transmission method, device and equipment, a medium and a product, and the method comprises the steps: reading a data transmission table entry of a first random access memory according to a queue number; obtaining a new address of the current working queue event in the second random access memory from the idle pointer storage queue; when the data sending table item is invalid, updating the information of each table item, and writing the work queue event data into the data operation table item; and writing the queue pair number into the scheduling information storage queue. When the data sending table item is valid, updating each table item; and establishing a new data operation table item on the second random access memory according to the new address, and writing the work queue event data into the new data operation table item. According to the method, the random access memory is used for processing the work queue
