Chapter 1
Analyzing Business
Goals and Constraints
This chapter serves as an introduction to the rest of the book by describing top-down
network design. The first section explains how to use a systematic, top-down process
when designing computer networks for your customers. Depending on your job, your
customers might consist of other departments within your company, those to whom you
are trying to sell products, or clients of your consulting business.
After describing the methodology, this chapter focuses on the first step in top-down network
design: analyzing your customer’s business goals. Business goals include the capability
to run network applications to meet corporate business objectives, and the need to
work within business constraints, such as budgets, limited networking personnel, and
tight timeframes.
This chapter also covers an important business constraint that some people call the
eighth layer of the Open System Interconnection (OSI) reference model: workplace politics.
To ensure the success of your network design project, you should gain an understanding
of any corporate politics and policies at your customer’s site that could affect
your project.
The chapter concludes with a checklist to help you determine if you have addressed the
business issues in a network design project.
Using a Top-Down Network Design Methodology
According to Albert Einstein:
“The world we’ve made as a result of the level of thinking we have done thus far creates
problems that we cannot solve at the same level at which we created them.”
To paraphrase Einstein, networking professionals have the ability to create networks that
are so complex that when problems arise they can’t be solved using the same sort of
thinking that was used to create the networks. Add to this the fact that each upgrade,
patch, and modification to a network can also be created using complex and sometimes
4 Top-Down Network Design
convoluted thinking, and you soon realize that the result is a network that is hard to
understand and troubleshoot. A network created with this complexity often doesn’t perform
as well as expected, doesn’t scale as the need for growth arises (as it almost always
does), and doesn’t match a customer’s requirements. A solution to this problem is to use a
streamlined, systematic methodology in which the network or upgrade is designed in a
top-down fashion.
Many network design tools and methodologies in use today resemble the “connect-thedots”
game that some of us played as children. These tools let you place internetworking
devices on a palette and connect them with LAN or WAN media. The problem with this
methodology is that it skips the steps of analyzing a customer’s requirements and selecting
devices and media based on .

Local area network (LAN
Local area networks connect groups of computers and low-voltage devices over short distances (within a building or between a group of two or three buildings very close to each other) to share information and resources. Businesses generally manage and maintain local networks. Through the use of routers, LANs can connect to wide area networks (WANs, explained below) to transfer data quickly and securely.
Most local area networks have a router that connects to the internet. So being on such a local area network, you can communicate with other devices on your network and are protected from internet-based sniffing and monitoring software (i.e. things on the internet can’t see your internal traffic between devices). And yet, you still have the ability to go out to the internet by simply entering an internet IP address in your browser’s URL field.
7
Wireless local area network (WLAN)
WLANs use wireless network technology, such as Wi-Fi. Generally seen in the same types of applications as local area networks, these types of networks do not require devices to rely on physical cables to connect to the network.
You can access network resources from any location within the wireless network's coverage area. Wireless access to the Internet and to company resources help your staff be more productive and collaborative.
You don't have to string cables, as you do with wired networks. Installation can be quick and cost-effective. You can easily expand WLANs where and as needed, because no wires are involved.

This document discusses application assembly using web services. It proposes that web services allow non-technical people to construct complex business software by assembling reusable software components/services. However, there are still challenges to address like how to take abstract concepts into software and ensure quality attributes like performance and security. The document presents a "separation continuum" model to understand the different elements that make up business systems from abstract requirements to software implementation. It argues that application assembly using independently developed web services is feasible if standards are followed and the right assembly tools are available.

IRJET- Implementation of Dynamic Internetworking in the Real World it Domain
This document summarizes a study that implemented a dynamic internetworking in a real-world IT domain. The study created a network topology for an organization using Cisco Packet Tracer with routers, switches, computers and a DHCP server. It configured routing protocols, access control lists, authentication, VLANs and inter-VLAN routing. DHCP was configured to automatically assign IP addresses. Routing protocols like RIP, OSPF and EIGRP were configured between routers. Access control lists were used to filter traffic and provide security. Authentication ensured security and remote access was provided using telnet. VLANs divided the network into broadcast domains and inter-VLAN routing allowed communication between VLANs.

Introduction
West Consulting Firm is a large company with 1000+ devices
The best Network design for West Consulting Firm is Hierarchical structure as proposed in the network summary document
Hierarchical network design is a three layer model.
West Consulting is a large organization as it currently have 1000 users and it intends to increase the number of users to 1500
The reason as to why the organization should opt for a hierarchical network design due to:
Better scalability
Better redundancy
Better performance
Batter management and troubleshooting
Better policy creating and scalability
2
Hierarchical Network Design
In each layer in the hierarchy provides specific functions which helps the network designer to select and optimize the right network hardware , features and software
The access layer provides user access to the organization network
The distribution layer provides policy-based connectivity
Core layer provides fast transport between the distribution switches
Access layer is where the switches are located which are then connected to the end users or computers
The distribution layer separates the access and the core layer. It in this layer where the policy of the network is defined
The core layer consists of the layer with the fastest, biggest, and the most expensive routers. This layer is considered to be the backbone of the organizational network. It is in this layer that routers are used to merge geographically separated network of the organization

Cisco Design Principles of a Hierarchical Structure
When designing hierarchical network structure there four design principles to consider which are:
Network diameter: This term is used to measure the number of devices
Bandwidth aggregation: This is the art of considering the specific bandwidth requirements
Redundancy: This is the practice of duplicating critical elements so as to achieve reliability (Thomadsen, 2005).
Network diameter is the first thing to consider when designing a hierarchical network structure. Network diameter is the number of gadgets or devices that a certain packet have to cross before it reaches its destination. This means that when designing west consulting network structure, the network designer must keep network diameter low.
Bandwidth aggregation: The designers of West Consulting firm network structure they must consider the bandwidth requirement for every party of the hierarchy. Link aggregation is said to allow multiple switch ports links to be combined. This in turn achieves a high throughput between the organizational switches
To ensure redundancy the network designer can double the network links

Local area network (LAN
Local area networks connect groups of computers and low-voltage devices over short distances (within a building or between a group of two or three buildings very close to each other) to share information and resources. Businesses generally manage and maintain local networks. Through the use of routers, LANs can connect to wide area networks (WANs, explained below) to transfer data quickly and securely.
Most local area networks have a router that connects to the internet. So being on such a local area network, you can communicate with other devices on your network and are protected from internet-based sniffing and monitoring software (i.e. things on the internet can’t see your internal traffic between devices). And yet, you still have the ability to go out to the internet by simply entering an internet IP address in your browser’s URL field.
7
Wireless local area network (WLAN)
WLANs use wireless network technology, such as Wi-Fi. Generally seen in the same types of applications as local area networks, these types of networks do not require devices to rely on physical cables to connect to the network.
You can access network resources from any location within the wireless network's coverage area. Wireless access to the Internet and to company resources help your staff be more productive and collaborative.
You don't have to string cables, as you do with wired networks. Installation can be quick and cost-effective. You can easily expand WLANs where and as needed, because no wires are involved.

AA using WS vanZyl 2002-05-06
This document discusses application assembly using web services. It proposes that web services allow non-technical people to construct complex business software by assembling reusable software components/services. However, there are still challenges to address like how to take abstract concepts into software and ensure quality attributes like performance and security. The document presents a "separation continuum" model to understand the different elements that make up business systems from abstract requirements to software implementation. It argues that application assembly using independently developed web services is feasible if standards are followed and the right assembly tools are available.

IRJET- Implementation of Dynamic Internetworking in the Real World it Domain
This document summarizes a study that implemented a dynamic internetworking in a real-world IT domain. The study created a network topology for an organization using Cisco Packet Tracer with routers, switches, computers and a DHCP server. It configured routing protocols, access control lists, authentication, VLANs and inter-VLAN routing. DHCP was configured to automatically assign IP addresses. Routing protocols like RIP, OSPF and EIGRP were configured between routers. Access control lists were used to filter traffic and provide security. Authentication ensured security and remote access was provided using telnet. VLANs divided the network into broadcast domains and inter-VLAN routing allowed communication between VLANs.

Network upgrade
A proper site survey is necessary when planning a network upgrade to gather key information about the existing network infrastructure, user needs, physical layout, and future growth requirements. The site survey involves documenting details like the number of users and devices, applications used, existing hardware and configurations, wireless needs, reliability expectations, and budget constraints. This information provides an accurate baseline for designing an upgraded network that supports current and future business needs. A site survey also identifies any deficiencies in the current network to be addressed in the upgrade proposal.

Introduction
West Consulting Firm is a large company with 1000+ devices
The best Network design for West Consulting Firm is Hierarchical structure as proposed in the network summary document
Hierarchical network design is a three layer model.
West Consulting is a large organization as it currently have 1000 users and it intends to increase the number of users to 1500
The reason as to why the organization should opt for a hierarchical network design due to:
Better scalability
Better redundancy
Better performance
Batter management and troubleshooting
Better policy creating and scalability
2
Hierarchical Network Design
In each layer in the hierarchy provides specific functions which helps the network designer to select and optimize the right network hardware , features and software
The access layer provides user access to the organization network
The distribution layer provides policy-based connectivity
Core layer provides fast transport between the distribution switches
Access layer is where the switches are located which are then connected to the end users or computers
The distribution layer separates the access and the core layer. It in this layer where the policy of the network is defined
The core layer consists of the layer with the fastest, biggest, and the most expensive routers. This layer is considered to be the backbone of the organizational network. It is in this layer that routers are used to merge geographically separated network of the organization

Cisco Design Principles of a Hierarchical Structure
When designing hierarchical network structure there four design principles to consider which are:
Network diameter: This term is used to measure the number of devices
Bandwidth aggregation: This is the art of considering the specific bandwidth requirements
Redundancy: This is the practice of duplicating critical elements so as to achieve reliability (Thomadsen, 2005).
Network diameter is the first thing to consider when designing a hierarchical network structure. Network diameter is the number of gadgets or devices that a certain packet have to cross before it reaches its destination. This means that when designing west consulting network structure, the network designer must keep network diameter low.
Bandwidth aggregation: The designers of West Consulting firm network structure they must consider the bandwidth requirement for every party of the hierarchy. Link aggregation is said to allow multiple switch ports links to be combined. This in turn achieves a high throughput between the organizational switches
To ensure redundancy the network designer can double the network links
4
How Design a Hierarchical Network .
Get ahead of the cloud or get left behind
An enterprise cloud computing strategy results in:
Broad consensus on goals and expected results of moving select processes to the cloud
Standardized, consistent approach to evaluating the benefits and challenges of cloud projects
Clear requirements for the negotiation and monitoring of partnerships with cloud service providers
Understanding and consensus on the enabling and managing role IT will play in future cloud initiatives
Goals and a roadmap for transforming internal IT from asset managers to service broker
