Embodiment Construction
[0049] In order to solve the traffic problem generated during the transmission of large files when the client cannot be identified to download large files in the prior art, the present application provides a traffic identification method and device based on FTP download.
[0050] refer to figure 1 As shown in the work flow chart, the embodiment of the present application provides a traffic identification method based on FTP download, the method is applied to a traffic identification device, and the traffic identification device is set between the client and the FTP server, and the method includes The following steps:
[0051] Step 101, obtain the FTP message sent by the client.
[0052] Usually, the client needs to interact with various servers when browsing web pages or downloading files. On this basis, a traffic identification device is set between the client and the server, and the traffic identification device can obtain messages generated during the interaction between ...

The present application provides a traffic identification method and device based on FTP downloading. In the method, the first type of FTP message in the FTP message is first identified, and according to the first download information corresponding to the first type of FTP message, it is judged Whether there is a cache corresponding to the first download information in the multi-thread cache, if it exists, it means that the file corresponding to the first type of FTP message is already in the transmission process, if the cache corresponding to the first download information is not identified It is the cache generated when the client downloads, counting the number of caches corresponding to the first download information; if the number of caches corresponding to the first download information is greater than the preset threshold, it means that the first type of FTP message corresponds to The file transmission is multi-threaded transmission, so that the first type of FTP message is determined to be the message generated when the client downloads, which solves the problem that in the prior art, when the client downloads a large file, the traffic generated during the large file transmission process cannot be identified. question.
Description
technical field [0001] The present application relates to the technical field of flow control, in particular to a flow identification method and device based on FTP download. Background technique [0002] With the development of network technology, the demand of network users for large file transfer is gradually increasing. Currently, large file transfer methods mainly include HTTP, FTP, and P2P, among which FTP (File Transfer Protocol, file transfer protocol) is a relatively widely used large file transfer method. [0003] FTP adopts the client-server mode. When the client uses FTP to download large files, there are mainly two stages. In the first stage, the client establishes a connection with the resource server, and obtains the storage address of the large file on the resource server. In the second stage, the client establishes a connection with the FTP server, and the FTP server transmits the large file to the client. When the client uses FTP to download large files, ...
