基于UNIX的FTP枢纽服务器软件的设计

SOFTWARE DESIGN FOR UNIX-BASED FTP PIVOT SERVER

为了改善目前大型系统之间文件传输效率低下的状况,提出了"FTP枢纽"的新概念,讨论了FTP枢纽服务器所用的技术架构,通过FTP枢纽服务器软件的需求分析,给出了软件的模块划分,设计中采用了分层模式和中心控制模式(Server/Client)相结合的设计方式,更适于软件的完善和扩展。在概要设计的基础上,详细说明了用来业务注册的智能向导模块的设计思路,同时提出"文件处理引擎"的概念,"处理引擎"中的各模块具有可方便插拔的特性,使系统便于剪裁。FTP枢纽基于UNIX服务器和JAVA编码的设计具有良好的可移植性,可以平行地移植到多个领域,体现了较高的实用价值。

In order to improve inefficient file transmission between large-scale systems at present,a new concept of ‘FTP pivot＇ was proposed.The technical architecture which the FTP pivot server uses was discussed,and the division of software＇s module was given through the demand analysis of the FTP pivot server software.The design mode of combining hierarchical model with centric control model（Server/Client） was used when designing,which adapted to perfecting and expanding the software more.On the basis of sketched design,the design idea of intelligent wizard module for business registration was dwelled on,simultaneously the concept of ‘Document processing engine＇ was proposed.In ‘processing engine＇,each module has the characteristic enabling plug-pull to facilitate system＇s rescaling.The design of FTP pivot based on UNIX server and JAVA code has good portability and can be transplanted to many domains in parallel,which manifested a higher practical value.
