Problems solved by technology

This method solves the problem of server performance, but since all user requests are aggregated to one point, a large amount of backbone network traffic is generated, and it is easy to cause network bandwidth bottlenecks. At the same time, the cost of this solution is very high
[0006] The second method is that some FTP systems artificially limit the number of concurrent connections from the client to the server to ensure that most clients have a faster response speed, but this method means that the FTP server will abandon the connection in a certain period of time. Some users, and cannot meet the needs of business growth, so this solution is unreasonable

Abstract

The invention discloses CDN system and method to realize the distributed FTP service, the system includes: media source library that works as the FTP download content source of CDN system; managing support system, which manages the FTP download business of CDN system and device management; content route / load balanced system, which is used in the whole CDN system, and schedules the requirement of FTP download content to certain service spot; CDN node network, which works as the device cluster providing FTP download service; and user terminal which is used to download FTP in the CDN system.

Description

technical field [0001] The present invention relates to data communications. More specifically, the present invention relates to a system and method for realizing FTP download service through a CDN network. Based on CDN (Content Distribution Network) network, the present invention realizes a distributed FTP download service system and its method. Background technique [0002] With the development of broadband Internet, downloading has become a major network application. According to the survey by CNNIC, 37% of the users in the survey of frequently used network functions choose to download. Among them, the FTP download method is widely used because of its fast transmission speed, stable connection, and functions such as resuming uploads from breakpoints. [0003] The FTP download service is implemented based on FTP (File Transfer Protocol), and adopts the working mode of C / S (that is, client / server). The traditional implementation method is a simple many-to-one structure,...
