Design And Implementation Of Network Applications For Large File Transfer Service

With the development of computer science, application development gradually from the traditional stand-alone applications to web application development distributed multi-machine communication. Many applications require the network to realize the transfer from one party to another file. Therefore, network file transfer service is often an integral part of the application. As the demand from different backgrounds, different development language, these documents are often repeated transfer service development, and security and reliability issues tend to be ignored. Content of this paper is to propose a system-oriented network applications large file transfer service, to solve large file transfer process safety and reliability issues by way of independent services and file transfer services and network applications other features decoupling module.This article on the "network acceleration system" project to build the foundation and background, the project requires the file transfer module with other modules with low coupling characteristics. Various development languages, the system needs to be summarized version of the acceleration system for a variety of large log file information to a log server problem, the design of a file transfer service system, using independence and the path of thinking, to achieve a large file fast and efficient transfer. After laboratory testing and on-line operation, good experimental results obtained.In addition, the development and design of this article during the system, while taking into account the safety and reliability issues and to use file transfer protocol UDT as a file transfer protocol. With the effective use of existing mature technologies coupled with further design, making the system more perfect and rich.
