Abstract
Business and business processes are becoming increasingly information intensive. The marketplace is responding to this need with never-ending increases in computational ability and application software sophistication. These evolutionary changes in processors and applications impose challenging and variegated performance requirements on the networks that support them. Consequently, data communications and networking are becoming increasingly vital to the success of information users.
Networking technologies, historically, have been largely regarded as the proverbial black box. Few, if any, people really understand the mechanics of these vital technologies. As information technologies become more complex, they will require very different levels of network performance. Networks will continue to evolve in response to these technological innovations. They will continue to become faster and more feature-rich.
The key of success will be to match the features and functionalities of networks to the attributes and performance requirements of the networked processors and applications. This requires everyone, from IT executives and managers to application programmers and network administrators, to understand the abilities, the limitations, and the performance requirements of each piece of the IT infrastructure, and to work together to craft cohesive solutions.
Therefore, this thesis is introduced to specify the network performance parameters and define the network performance evaluation techniques, and then analyze and evaluate the most important internetworking protocols from the perspective of network performance. Then some network analyzers are used to show a way to evaluate, optimize and manage the network performance of an existing network.
The thesis consists of five chapters, and the references.
