| One practical ideas of the development of the Internet in the future is service providing oriented architecture. And the key of the implementation of this architecture is the study of the technologies of open and reconstructive routing and switching node in which a development environment, studied and implemented in this thesis, of reconstructive routing and switching may play a supporting role.(1) At beginning, the three levels, including platform, packages and components, of the processing of reconstructive routing switch systems are defined in this thesis. Platform is a system that can perform many tasks via reconstruction; packages are the units that can fulfill specified functions via reconstruction;and components are modules that can do specified processes via reconstruction.(2)Instructed by the methodologies of software engineering in the development of components, this thesis provides an architecture module and an implementation framework of the development environment of reconstructive routing and switching based on the platform of reconstructive routing. This thesis also studies the software methods of development environment of reconstructive routing and switching as well as the basic problem of the reconstructive ability of components. And from these researches, this thesis abstracts the components module, raises the principles of design and development of components, studies the description, simulation and testing of components(3)Eventually has designed and implemented the integrated compiling development environment of reconstructive routers.By the standards and open development flows it provides, the development of components becomes more than the simple development of objects but also the solving of problems of reasonability and reconstruct ability of components in a high level. Besides, this development environment provides component-based packages generating framework by which the library of component units could be developed more conveniently and quickly.(4) At last, this thesis develops the component instances according to the advised developing methods and verifies the reconstructive ability.The studies in this thesis will provide important supports for the design and implementation of open reconstructive routing and switching node and help implement the architecture of service providing oriented new type Internet technologies. It is very hopeful that the specific methods of components generating and the specification of relevant test could be regarded as the basics and standards of the industry technology of the domestic manufacturers in the realm of routing and switching as well as the operators of networks and be the one of the mainstream technologies of the international networks. |
