Part II Network Analysis, Architecture, and Design CpE654 / NIS654 Design and Analysis of Network Systems Week 04 1 5/30/2012 CpE/NIS 654
For this Part II of the course, we will primarily follow the methodology as described in McCabe book but supplement it from Peterson/Davie book or other sources as appropriate Network Design Methodology 2 5/30/2012 CpE/NIS 654
Chapter 1 – Introduction Network Analysis, Architecture, and Design Network Design Methodology 3 5/30/2012 CpE/NIS 654
3-Part Methodology The 3 part methodology described 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. 4 5/30/2012 CpE/NIS 654
Network analysis, architecture, and design are similar to other development processes in 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 implementation Network analysis, architecture, and design 5 5/30/2012 CpE/NIS 654
Information flows between network analysis, architecture, and design 6 5/30/2012 CpE/NIS 654
Network Analysis Network analysis is the step to: understand what problems we are trying to solve 9 understand the users’ needs 9 understand the system requirements compile information that will be used in developing and architecture and design If 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).
