Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 It is a flowchart of a method for fast data transmission based on the TCP protocol. The method includes the following steps.

[0037] In step S01, the responding end receives a file request sent by the requesting end, and the file request includes the IP address of the requesting end. The answering end can be any device that can send files, such as a server. The requesting end may be a terminal device used by the requesting user, for example, a computer, a mobile phone, a handheld computer and other user ends. Specifically, the client requests the server to download a file, and the server transmits the file to the client. The file includes but is not limited to pictures, word documents, pdf documents, comp...

Abstract

The invention provides a TCP-protocol-based burst data transmission method and apparatus. The method comprises: a response side receives a file request sent by a request side; the response side obtains an IP address of the request side according to the file request; the response side determines whether the IP address of the request side exists in a database; if not, file transmission to the request side is started based on a default initial TCP window size and the IP address and the transmission rate of the request side are stored in the database; and if so, the initial TCP window size is calculated according to the stored transmission rate and the RTT based on statistics, file transmission is carried out based on the initial TCP window size, and the transmission rate is updated. According to the method, the initial TCP window size is decided according to bandwidths of different request sides; the time of file downloading by the request side is reduced; and the network resource utilization rate of the request side is improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for fast data transmission based on TCP protocol. Background technique [0002] In the era of Internet development, the download bandwidth of ordinary users is relatively high, such as above 2M. However, when the user downloads data from the server, the initial download rate starts from very small, and then slowly increases the download rate. Different users have different network bandwidths. For users with high network bandwidth, when downloading a file, the download rate starts from very small and then increases slowly, which makes the download speed very slow, and it takes a relatively long time to download a file, and the user's network resource utilization is not high. . Especially for downloading small files is more obvious. Contents of the invention [0003] In order to solve the problem of slow file transfer speed and low utilization rate of net...
