Network storage system and method based on UDP protocol

The invention discloses a network storage system and method based on a UDP protocol, and the system comprises an access control module which is used for receiving an authentication request and building session connection; a command processing module which acquires the operation request, analyzes the operation type, executes the operation and returns an execution result; a transmission control module which sends a to-be-read file data packet according to the operation request, adds an HUP protocol header to the to-be-read file data packet, and sends the file data packet through a UDP, receivesa to-be-written file data packet according to the operation request, extracts an HUP protocol header of the file data packet, and verifies the data according to a serial number and a verification codein the HUP protocol header; and a data access module which is used for reading and writing the file data packet by adopting an asynchronous reading/writing interface. According to an implementation method for reliable transmi
