Acceleration method and system based on CIFS protocols

Abstract

The invention provides an acceleration method and system based on CIFS protocols. After an acceleration node receives a file request, if needed file data exists in a local cache file and the local cache file is not overdue, the needed file data is read from the local cache file; if needed file data exists in the buffer memory block, the needed file data is read from the buffer memory block; otherwise, the size of the request is increased; after response data of a source station is received, a local buffer file is updated, and residual data is stored in the buffer memory block; and data in response to the original size of the request is sent to a client. The acceleration method and system based on the CIFS protocols effectively reduce the frequency of direct data transmission between the client and the source station and accelerate data transmission by data pre-reading and buffer memory.

Description

technical field [0001] The invention relates to network data transparent transmission acceleration technology, in particular to an acceleration method and system based on CIFS protocol. Background technique [0002] CIFS (Common Internet File System, common network file system) is a service for sharing files between Microsoft Windows hosts through the network, and is usually called My Network Places. Generally speaking, CIFS can be regarded as an implementation of application protocols, such as file transfer protocol and hypertext transfer protocol. CIFS uses a client / server model. Specifically, the client requests a server program located far away on the server to provide services for it. The server obtains the request and returns a response, so that the user on the client can read and write files on the remote host as if accessing a local file, and can share and collaborate with other users on files. [0003] CIFS is a public or open version of the SMB (Server Message B...

AI Technical Summary

Problems solved by technology

[0015] (1) The client needs to upload or download the same file multiple times. Since the application acceleration network does not analyze the application layer protocol and only performs transparent transmission, it needs to transmit complete data every time, and the transmission time is long;

[0016] (2) The client can only request 16K data blocks at a time, and needs to request multiple times, and each data block needs to be confirmed, which consumes too much time to go back and forth;

[0017] (3) The existing CIFS protocol application scenarios are mainly in file sharing, which means that most of the requests are just for files, and the files are generally not changed, or the frequency of changes is very small, so that the cache cannot be fully utilized. Advantages to increase the response speed of the system, and it is easy to get stuck when multiple users access the same file at the same time
