It has become an important feature of the work of designers to determine the problems that exist in his network, choose and analyze several optimization parameters during the analysis process, and then prioritize and evaluate the parameters in the architecture and design of the system. Network Analysis, Architecture, and Design, 2e, uses a systems approach methodology for teaching these concepts, which saw the network (and the environment it impacts) as part of a larger system, looking at interactions and dependencies between the network and its users, applications, and device. Network architecture takes the input from network analysis and provides a high level view of the network, focusing on the relationship between the main functions of the network, such as security, network management, performance and addressing and routing. With a number of examples, analogies, instructor tips, and exercises, this book works through a process of analysis, architecture, design and step by step, giving network designers a powerful resource for making good design decisions * Substantial revision of the first edition so popular - Practical Computer Network Analysis and Design - by an experienced architect who has led many network design projects in government, commercial and academic space.
