Design And Implementation Of Wide Area Network Data Transimission Sysytem Supporting Differentiated Requirements

With the development of network technology and multi region cooperation of enterprise business,the high performance and high reliability of data transmission in wide area network are necessary characteristics of the system.But the wide area network for data transmission is facing to develop a new transmission system in the face of the different needs of the business.This will exacerbate the system development cycle,waste a lot of manpower and material resources.This paper outlines the difference dissimilation demand in the transmission system of the wide area network of universality,analyses the transmission system of different users and different business to provide differentiated service demand,and in the wide area network environment,transmission software of different needs of the hierarchical structure of the design and implementation of,this paper from supporting the needs of different angle of,design and implementation of a wide area network,data transmission system.This paper analyses and researches the demand for wide area network data transmission process from the client/server model,sums up the needs of different functional requirements and business needs.In order to reduce the degree of coupling transmission system,reduce system updating and development effort,reference operating system microkernel model,transmission system is divided into different levels of the hierarchy,transfer function is concentrated in the kernel abstraction layer,and achieve the functional requirement as much as possible.Different business needs are independent of the kernel level abstraction layer,and interact with transmission module through the interface design.This paper analyses and summarizes the demand for business logic,then designs and implements the rationality of the system on the part of the business demand characteristics,and scenario testing is performed for two task trigger mechanisms,which are message mechanism requirements and source file polling requirements.The design and implementation of this paper can be used in the simple and easy transmission system network,and in the complex data transmission requirements,it can develop interface for further business development according to the system and reduce effort.This is very important for the transmission business,so that the developer can pay more attention to the business logic,which has certain contribution and significance to the development of wide area network data transmission.
