Example Embodiment

[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please refer to figure 1 , the present invention provides a transmission method that can quickly download a large number of small files in a high-latency scenario, comprising the following steps:

[0039] S1: The client establishes a TCP connection with the server, and sends the login information to the server. The server checks whether the login information is correct. If it is correct, the login is successful. Specifically, in this embodiment, the login information includes: a user name and a password.

[0040] The structure of the message sent by the client to the server is as follows:

[0041]

[0042] where user_name is the username and pass_word is the password.

[0043] S2: After the client successfully logs in, it checks the file directory displayed on the server, and sends an acquisition instruction for acquiring all files...

Abstract

The invention discloses a transmission method capable of quickly downloading a large number of small files in a high-delay scene, and the method comprises the following steps: enabling a client to send login information to a server, enabling the server to check whether the login information is wrong or not: if the login information is not wrong, determining that the login is successful; after the client logs in successfully, checking a file catalog displayed on the server, and sending an obtaining instruction for obtaining all files under a specified catalog to the server; enabling the server to sequentially traverse all the files under the specified catalog and sending file information corresponding to all the files under the specified catalog to the client one by one; when the client side receives file information corresponding to any file in the specified directory, sending a file downloading instruction to the server; enabling the server to search a corresponding file according to the file downloading instruction and sending the file to the client. According to the invention, a TCP connection is established, all control messages and file data are ensured to be transmitted on the TCP connection, and the downloading operation process of the client can be effectively accelerated.

Description

technical field [0001] The invention relates to the field of file transmission, in particular to a transmission method capable of quickly downloading a large number of small files in a high-delay scenario. Background technique [0002] When using the FTP protocol to transfer files, each file requires the client to establish two TCP connections with the server, one is used to transfer instructions, and the other is used to transfer actual data. The channel for transmitting instructions needs to perform a login operation after the connection is established, and the account number and password are sent separately, and the authentication operation requires 2 RTT (Round-Trip Time) to complete. [0003] After the login operation is completed, a command to switch the working directory needs to be sent, and the file download operation can only be started after the server responds successfully. When traversing directories before FTP downloads files, only one layer of directories can...
