This report describes a project which creates an upgraded topology based on the Internet service provider (ISP) environment. In the current service provider network, reliability, availability and management have become issues which need to be considered. Many technologies have been presented to solve these issues. This project is based on the virtual environment finished by simulators which are tools necessary to accomplish the project. In this project, two simulators are applied. One simulator creates a network topology which can be used to simulate real architecture, check all the protocols and process packets exchange. The second simulator deals with traffic. In the virtual environment, the simulated traffic will be created, collected and analysed. From this operation, a report about the advantages and disadvantages in both the current and the upgraded network environments will be generated. Detailed results are then compared, explained and clearly presented using data format.
