Especificação de componentes para simulação de redes TCP/IP.

Abstract

The growth of the Internet demand continuous investment directed to the evolution of the TCP/IP technology. Study of the systems of the computer networks, commonly, use the digital simulation technique. In t h i s context, environments of simulation based in components emerge as alternatives that makes easy the build and performance evaluation of the general computer networks models. The approach to Component-Oriented software development determine that an application can be builded through a kit of components coupled. That approach to is a natural evolution of the approach to object- oriented, on that a component correspond to a inter-relacioned classes kit w i th limited extern view. That master dissertation presents a component specification concern to the modeling of the TCP/IP networks. The components are generics representing the minimum funcionalities of t he TCP/IP network's basic elements, such as traffic sources, hosts, links and routers. That specification was made making use of Unified Modeling Language (UML) focalizing mainly the plan and elaborate phase, the analyze phase and design high-level phase (architecture design). Several phases of development process documented in this dissertation can be reusable in the development of the environment of the component-oriented simulator, as well, can be reusable in the development of the specific simulators, both concerns to the network performance modeling and evaluation with the TCP/IP technology.
