Problems solved by technology

When transferring large files, these operations take negligible time, but when there are a large number of small files that need to be transferred, these things also need to be done, so the whole process takes up a relatively large proportion of system and network overhead, and it becomes important factors affecting network performance

Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] The present invention provides a method for uploading data of the FTP protocol, the method comprising: S101, an ordinary node sends an upload data request to a key node; S102, the key node receives the upload data request, and sends an acknowledgment to the ordinary node Sending information; S103, the common node uploads data to the key node after receiving and confirming the sending information; and S104, the key node receives the data, and uploads the data to the server.

[0029] Through the above embodiments, the method for uploading data of the FTP protocol of the present invention reduces the data transmission time, improves network performance, and ...

Abstract

The invention discloses a method for uploading and downloading data for an FTP (file transfer protocol). The method for uploading data comprises the following steps that S101, a common node sends a data uploading request to a key node; S102, the key node receives the data uploading request and sends a transmission confirmation message to the common node; S103, the common node uploads data to the key node after the transmission confirmation message is received; S104, the key node receives the data and uploads the data to the server. The method for uploading and downloading data for the FTP performs mass small file transmission by the FTP, thereby guaranteeing fast transmission of files.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method for uploading data and a method for downloading data of the FTP protocol. Background technique [0002] Although TFTP can efficiently transfer a large number of small files, its bottom layer is based on UDP and does not provide reliable transmission; although GridFTP also ensures efficient transfer of small files, it requires users to install Globus software. For a large number of users, this is not practical; therefore, choosing the FTP protocol has become one of the choices for those who need reliable and efficient data transfer of small files. [0003] However, the use of the FTP protocol has such a feature that when transferring large files, it is not easy to disconnect and is relatively stable; but when transferring many small files, the speed becomes very slow. Because the bottom layer of FTP uses the TCP / IP protocol, when FTP transfers files, it needs to open the...
