Abstract

The invention provides a method and device for writing data based on a common Internet file system. The method comprises the steps of starting a thread to write SMB (Server Message Block) message datain a received file write request into a preset memory area; blocking the thread after it is monitored that the data is written into the preset memory area, and embedding a thread identity of the blocked thread into a preset waiting queue linked list; shearing each thread identity to a preset synchronization queue linked list after it is determined that the thread corresponding to the thread identity in the waiting queue linked list is woken up; indicating the woken thread to read the SMB message data of the synchronization queue linked list in the memory area, and writing the data into a disk; and traversing the synchronization queue linked list after the data is written into the disk, returning write success information to clients mapped by the traversed thread identities in sequence, and waking up the thread corresponding to the thread identity in the waiting queue linked list after the write success information is returned to the client mapped by the lastly traversed thread. A utilization rate of bandwidth resources can be effectively improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and device for writing data based on a common network file system (CIFS, Common Internet Files System). Background technique [0002] CIFS is a communication protocol that provides access to remote servers for computer devices with various operating systems such as Windows / Linux / Mac OS in the network. In a Network Attached Storage (NAS, Network AttachedStorage) cluster, the NAS shared files in the nodes are based on the CIFS server for data transmission, providing shared and data backup files for computer equipment. Taking the Windows operating system as an example, a Windows client can access NAS shared files on a node through a CIFS server. Wherein, the CIFS server transmits data with the Windows client and the node based on the Server Message Block (SMB, Server Message Block) protocol. [0003] Since the CIFS server adopts the SMB protocol, S...
