Design And Implementation Of Customized Browser Based On Chinese Platform

In order to change the situation of replying on foreign browsers,this project develops a customized browser based on Chinese platform which is able to provide optimal performance.With the help of the new version of the business application system 2.0,this compatible browser with dual cores meets the requirement of 200,000 users across the country as along as with further extension.The new browser based on business application system 2.0 is capable to solve system compatibility and sustainability.The issue of security shows its significance in the construction of the new version of the business application system.The customized browsers is required to adopt technologies with independent intellectual property rights.The customized browser supports domestic operating system,UOS and other localized platforms to provide necessary security support for basic applications such as government requirements.The development of customized browser learns from the years of experience during information construction.The researchers gather the requirements from real industry,study the working process and get feedback from end users.Subsequently,they pay attention to the core of business and sore point of this this industry.It is demanded to create a customized browser with compatibility,stability,and adaptability.The testing and verification are necessary to make sure the browser meets the industry standard.Requirements analysis and implementation of customized browser based on Chinese platform provide experience for future constructions.Standards on web development based on customized browser also have an important reference for the development of subsequent application systems.At the same time,it pays attention to improve efficiency of the office staff and reduce the cost of collaboration.With the goal of deep integration of the new version of the business application system 2.0 of the unit,it provides a unified business application system 2.0 access entrance and container.The browser described in this project is based on the W3C standard and is integrated with Chromium open source code.Chromium uses pre-DNS resolution and resource prefetching technologies in the network module to greatly reduce user waiting time,with new network protocols such as SPDY and QUIC to reduce network transmission time.Chromium uses NPAPI to encapsulate WPS and PPAPI to encapsulate FreeWML in terms of integrated plug-ins to solve compatibility problems.Besides,Chromium adopts a sandboxed renderer process to maximize the security of the agent process and the target process.V8 is the built-in JavaScript engine of Blink.Blink is the Chromium rendering engine,which can realize fast attribute access and dynamically generate machine instructions with efficient garbage collection capabilities.The browser encapsulates TCMalloc technology,which can efficiently allocate memory,reduce process fragmentation,and improve browsing The stability of the device.The system testing and results analysis of the customized browser are given at the end of the thesis.The completion of functional requirements and correctness of the browser are showed.It also describes the personnel configuration,and indicates the future potential extentions.
