Research And Implementation Task Management Center Based On Virtual Network Simulation System

Along with the rapid development of modern network system, today, computer simulation has become main tool for analysis and designs the network system, and plays a more and more important role in network system development and teaching. Today's network is oriented large-scale integrated multi-business network direction, and need network system simulation can make efficient simulation to subnet which has different function or running different network protocol. Facing the problems which are network resources scheduling, network data interaction and sharing in the research of the large-scale network, the article proposed virtual network simulation system, which is reconfigurable, open and capable for visualization and interactive with complex data, thus effectively promotes the large-scale network research.This thesis mainly research and implement task management center unit which makes the virtual network simulation systems become reconfigurable and interactive network simulation system. The first chapter introduced the concept and classification of system simulation and the application of computer simulation, and then expounded the virtualization and its significance; Chapter 2 analyzed and expounded virtual network simulation system by our designed, and also introduced the virtual operation center management subsystem and task management center subsystem,; Chapter 3 researched high level architecture based on distributed interactive simulation and analyzed component and develop executive process for high level architecture; Chapter 4 analyzed task management center structure and component modules, and then expounded design scheme for the data management system and general interface framework; Chapter 5 introduced optical network simulation platform based on the virtual network simulation system, as well as verified the feasibility of task management center on this platform; And an outlook of further research was made in the last chapter.The main work of this dissertation is listed as following:1. Participate in the design of virtual network simulation system scheme, it is a reconfigurable, open and interactive virtual network simulation and demonstration system, and it also connected with users and virtual network space, showing a brand-new way for the complex data visualization and interaction.2. Research and implementation task management center unit based on virtual network simulation system, using object reflective and polymorphism technology makes group members can share data, realize data and specific business logic separation, support data flexible expand and new members random access.3. Participate in the design and implementation of optical network simulation platform based on virtual network simulation system, through constructing test cases validate the function.
