Research And Implement Of A Lightweight Topology Display Mechanism Used In Mobile Device

With rapidly increasing of mobile devices and constantly developing of Mobile Internet,people can carry out their daily work, study and entertainment using their mobile devicesanytime and anywhere. Meanwhile the traditional IT Operations Management System ischanging from personal computer to mobile devices, which transport data by Mobile Internet.Topology is the entrance of the IT Operations Management System, but how to display thetopology fast, cleared and real-time on a mobile device is the most important thing. Bystudying the existing topology display technology, this thesis puts forward a kind oflightweight topology display mechanism used in mobile, this mechanism can show topologyon the mobile rapidly, accurately and clearly, and with connected to the server and the mobilethrough the Mobile Internet, the topology can be displayed real-time and dynamic. After anAndroid application development, the mechanism is verified feasible. This thesis mainlyincludes the following aspects:(1) This thesis adopts the mobile Internet combines server and mobile terminal. On theserver side, using data compression technology is for reducing the pressure of the mobileInternet data transmission, using the message digest technology is for marking the topologyfile and the uniqueness of the alarm message, using push technology is for download thetopology files and the warn messages, using data mining technology is for obtain real timealarm information. On the mobile, the message is download and displayed real-time anddynamic.(2) Because of the mobile equipments’ hardware resources is finite, this mechanism usesthe configuration files as well as the small format images in topology display on mobile,which is verified saving more resource and displaying faster. Because of mobile equipments’screen is small, this mechanism design the "cloud", with the "cloud" some of the topologyelements is shown together. The cloud is divided according to the structure characteristics ofthe topology, the topology properties and user privilege, which is verified displaying wholetopology clearly.(3) This mechanism can get the warn messages real-time and display clearly. The warnmessages is grading according to the alarm severity. While displaying, the different alarmlevel will show the different background color. The dynamic topology alarm can positionalarm device for the user more accurately, clearly and rapid, and also accelerate theoperational process.(4) On mobile devices this thesis uses the open-source Android platform, and on serverthis thesis used Eclipse and Tomcat development platform. The mechanism is developed, and the application runs well, it can show topology clearly and quickly on mobile devices,meanwhile the warn messages is shown dynamic and real-time.To sum up, this thesis can show the topology and warn messages real-time and clearlycombining with the Mobile Internet and the mobile. After programmed, the mechanism isverified feasible.
