Logically divided into three sections.› The first section covers the analysis process.
how to develop requirements, understand traffic flows, and conduct a risk analysis.
› The second section covers the architectureprocess. describe how to make technology and
topology choices for your network, how to understand the relationships among the various functions within your network.
› The third section covers the design process. describe where location information,
Equipment, and vendor selections are used to detail the design.

Network analysis, architecture, and design are processes › used to produce designs that are logical,
reproducible, and defensible.› Logical : design concepts (process steps). › Reproducible : produce again(customize).› Defensible : able to be protected.

Assist the planning and management of complex designs.
It Involves mapping of relationships(graphical representation) between Users/Clients, organizations(vendors), devices, applications on the networks.
It includes: › Descriptions about problem with existing network› Descriptions of requirements for network› Descriptions of traffic flows(interaction bw S/D)› Descriptions of potential risks(possibility of loss)› (lists of risks: product related ,business related ,customer
,dvlpmnt , process , technology )

It is also known as network analyser(tool). Stand alone hardware device and
designed with a specialized software. Who uses network analyser:› System Administrators› Network Engineers› Security professionals
![Page 8: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/8.jpg)
Why administrators use network analyser
› Converts binary data( 0’s and 1’s into human readable format(text, images, audio and videos).› Capturing the network traffic.› Troubleshooting problems on network.› Discovering a faults/failures on network.› Analyzing the operations/the performance.› Detecting spyware (gathering information)

Two aspects:
First: › To listen to users/clients/customers and
understand their needs/requirements. Second:› understand the users/clients/customer’s
system. Language independent(.net , java etc.) Platform independent(windows/linux etc.)

Network architecture uses the information from the analysis process › to develop a conceptual, high-level structure for the
network. It is a ‘framework’ such as( functions, operational
principles, re-usable components, procedures etc.) It may also include a detailed description of
products/designs and services. It includes:
› Determines sets of technology and › Topology choices for the network.› Determine the relationships among the network functions
such as switches, routers).

Network design provides physical design to the architecture.› Aim: To Build/Design the best network for
organizations(vendors).› to composing topological design(based on
size / area). Physical design includes:› blueprints and drawings of the network› Vendors selections, and equipment selections
design boundaries and design validation.

Set of process components represents › a complete implementation of network analysis,
architecture, and design.

Analysis product: › Enable us to understand the important
materials, processing, economic(financial) and decision making which are required before any product can be manufactured.
Analysis process : › A step by step breakdown of the phases of a
process, used to convey the inputs, outputs and
perform the operations that take during the each phase.

includes :
Identify the problem Collect information Develop solutions Generate ideas Select an approach Build a model / design Improve on your design
![Page 19: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/19.jpg)
Network analysis, architecture, and design are part of the engineering process that form the basis of networking projects.
Such projects have immediate(current-term), tactical (near-term), and strategic (long-term) significance.
These plans are designed to be iterative and should be regularly reviewed.
![Page 20: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/20.jpg)
![Page 21: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/21.jpg)
![Page 22: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/22.jpg)
![Page 23: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/23.jpg)
While the current target will be a network design, the near-term and long-term targets can be proposed enhancements to the current target.
The idea behind this plan is to develop a network design that will be implementedwithin one year, it will prepare us for any changes we might need to make to the network within three years, and will keep us in the direction of what is planned for five years in the future.
![Page 24: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/24.jpg)
The long-term (five-year) target is a rough estimate.
We will likely not know what new networking technologies, services, or levels of performance will be available five years out, nor
will we know how our customers’ business plans will change, nor
what network problems will arise during that time.
![Page 25: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/25.jpg)
The current (one-year) target should be well understood and is the focus of our analysis, architecture, and design effort.
Experience shows that one-/three-/five-year plans are very good starting points, but depending on your customers, you may rapidly evolve your network with a longer-term view with a one-year/five-year/ten-year plan.
![Page 26: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/26.jpg)
These plans are intended to be iterative and should be regularly reviewed, on the order of twice yearly, once per year, depending on your plan.
At each iteration the current, near-term, and long-term targets are reviewed and checked against the ongoing sets of problem statements, objectives, and requirements developed during the analysis, architecture, and design processes.
![Page 27: overview of analysis, architecture and design process](https://reader033.fdocuments.net/reader033/viewer/2022042607/559b73541a28abf8388b468a/html5/thumbnails/27.jpg)
Understanding Network and the System Complexity. Analysis helps us understand how technologies
influence / incorporate with networks, users, applications, and devices.
It allows planning & co-ordination of resources. It also reduces waste by efficient planning and
coordination of resources. how services can be incorporated into a
current state-of-the-art network.

Composition of concepts address the following areas:› Checking the levels of difficulties in the
technologies, potential architectures and designs.› Establishing and managing the customer
expectations.› Monitoring the existing network and the system.› Developing a set of options to solve problems.› Selecting one or more options.› Planning the implementation.

The study of methods by which we pursue network design.
Systems methodology means viewing the network that you are architecting and
designing, along with a subset of its environment.

System methodology used for describing important characteristics &capabilities of your network.
Provides basic connectivity and packet-forwarding performance for various services.
