Part IINetwork Analysis, Architecture, and DesignCpE654 / NIS654Design and Analysis of Network SystemsWeek 04 15/30/2012CpE/NIS 654
For this Part II of the course, we will primarilyfollow the methodology as described in McCabebook but supplement it from Peterson/Davie bookor other sources as appropriateNetwork Design Methodology25/30/2012CpE/NIS 654
3-Part MethodologyThe 3 part methodologydescribed in this course are:•Network Analysis: how to develop network requirements, flow, and risk analysis. • Network Architecture (logical design): how to understand the relationships between functions within your network and how to develop an architecture describing these relationships. Make technology and topology choices based on required functions.• Network Design (physical design): how to determine the technology selection and connectivity, based on location, equipment, and business considerations.45/30/2012CpE/NIS 654
Network analysis, architecture, and design are similar to other development processesin that they address the following areas:•Defining the problems to be addressed•Establishing and managing customers expectations•Monitoring the existing networks, systems, and their environment•Analyzing data•Developing a set of options to solve problems•Evaluating and optimizing options based on various trade-offs•Selecting one or more options•Planning the implementationNetwork analysis, architecture, and design 55/30/2012CpE/NIS 654

Network AnalysisNetwork analysis is the step to:•understand what problems we are trying to solve9understand the users’ needs9understand the system requirements•compile information that will be used in developing and architecture and designIf there is an existing network then we should study the current network components and know the problems that we have (e.g. study the performance of different devices such as routers and switches).
