Logical Vs. Physical Network Design Essay

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

When taking a look deep into an organization’s different departmental operation, it becomes clear how to plan to protect the most data and also which areas is more operation critical. While preventing interruption is the most important aspect of this plan, no one can predict the weather or any other attack. As part of the steps to implement the business continuity plan, Sunshine Machine Works will need to document a risk management plan, business impact analysis, incident response plan, plan activation, incident response team, communications, contact list and recovery plan section. Once all has been documented, the organization will need to test, evaluate and update schedule.

In order to provide speed and reliability, large and enterprise-level networks today are typically constructed in multiple layers. They are the access layer, also called the network edge layer, the aggregation or distribution layer; and the network core layer. The access layer is usually a mesh of network switches, linked to other switches in the aggregation layer, which in turn is linked to the core.

Before designing process it’s very important to analyze the usage of the network? For example, network will be used for business purpose (in offices), schools or hotels etc. If network will be used for business activities like for banks and other offices so administrator needs to deploy network for

As part of the first assignment, research and analysis of the downtime on a client’s primary network servers during the month of April must be done in order to further prepare a presentation to the company’s management.

The purpose of this project is to design a WAN (wide area network) using a Cisco Packet Tracer simulation. The Step by step instructions included in this project are designed to help provide an inside view of how to design any type of network using the Cisco Packet Tracer network simulation software. In addition i will also be looking at other software’s that are similar to the Cisco Packet Tracer and analyse the strengths and weaknesses of the software. I will also be looking into the types of network devices needed to design a WAN. Finally, I into the types of network architecture, network topologies and security management suitable for my design network project.

According to the book ‘Top down network design’ by Priscilla, and research by Pandya supports that a network is a group of devices connected together. There are many types of computer networks like, local area network (LAN), wide area network (WAN), campus area network (CAN), home area network (HAN), metropolitan-area network (MAN). Topology is the geometric arrangement of the computer system. The common topologies are bus, star, ring, mesh etc. Network topology refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. Network topology describes how the data is transferred between these nodes. There are two types of network topologies: physical and logical. Physical topology emphasizes the physical layout of the connected devices and nodes, while the logical topology focuses on the pattern of data transfer between network nodes. This paper investigates how different types of topologies work, its advantages and disadvantages.

Gaurav S. Patil is a graduate student in the department of telecommunication at the Southern Methodist University.

This project aims to provide the network design for a Big College. The project will demonstrate the ability to provide a network design to arrive at Server Network and Active Directory Infrastructure. The proposal demonstrates the critical thinking skills which involves using network analysis tool to achieve a technically feasible and reasonable business solution for Big College

A network topology describes how a network is physically laid out and how signals travel from one device to another. Since the physical layout of the devices and cables doesn’t describe how signals travel from one device to another, they are broken down into physical and logical topologies. Physical topology is the arrangement of cabling and how cables connect one device to another in network [1].Common example is LAN in which it uses as physical star topology(discuss later)and can

The first layer(interface layer) offers to the user a friendly and convenient entry to contact with the system.The second layer (application logic layer) implements the controlling functionalities and manipulating the underlying logic connection of information flows; finally the data modeling job is conducted by the database layer, which can store, index, manage and model information needed for this application [41].

My approach in this project and provided topic will be to apply a top-down network design process. I know that a top-down design is a process of reducing of an existing system into smaller parts, in order to understand its compositional sub-systems, essentially simplify given the problem scenario. Designed overview of the system, specifying, but not detailing any first level subsystems. Thus, every subsystem is refined in greater detail,

As a network engineer , It is main and most important factor while developing a network design is business analysis. So, by examining the client 's business and their goals, you can create a paper network design that meet the

Logical Topology – A logical topology of a network defines how devices on a network are structured and how they are connected. It shows the way that data and

Planning of Network Design: A proper planning of a network design will always lead to better results. Planning should be done in such a way that network should always run properly and should be secured 24/7. Strong firewalls and updated components are to be picked for proper planning of network. There should always be a space in network so that we can either expand or add few more components to network which will make network even more big. Blueprints of networks must be made prior to network design because they are the ones which will be helpful in designing the actual network.
