COIT20264 Network Design: A Presentation on Network Design Solution

This presentation details a network solution designed for Cosmos Online newspapers, focusing on establishing secure remote connections for freelance reporters to upload files and information to the organization's data center. The solution outlines aims and objectives, including enabling remote file access, analyzing data flow, and connecting network devices using appropriate IP addressing and cabling. Business goals emphasize efficient resource utilization and real-time database updating, while technical goals involve configuring routers and switches with appropriate networking protocols and developing a user interface with secure authentication. Constraints include understanding user requirements and the technical skills of the network developers. The design employs a mesh topology for redundancy, and tradeoffs include virtual server creation for load balancing and MPLS configuration for VoIP data transfer. The presentation also includes tables detailing user communities, data stores, traffic flow, and network application characteristics, as well as logical network design and physical security measures. The conclusion emphasizes the importance of security and resource availability, with various precautions applied to protect the network and organizational data. Desklib offers additional resources, including past papers and solved assignments, to aid students in their studies.

INTRODUCTION
The following presentation is prepared for Cosmos
Online newspapers for demonstration of the network
solution prepared for the organization. The network is
prepared for establishment of remote connection
between the freelancing news reporters and securely
upload files and information in the data centre of the
organization.

AIMS AND OBJECTIVES
 The following are the aims and objectives followed for the
development of the network solution
 To allow the freelancing news reporters to access the file.
Web and the web servers from remote locations
 To analyze the data flow in the current network for
monitoring the network activity
 To connect the network device following the IP addressing
and cabling plan.

BUSINESS GOALS
The followings are the list of business goals identified for the
development of the network.
 To utilize the resources efficiently for the configuration of the
network and reduce the errors.
 To configure the database of the servers and use higher
bandwidth for enabling real time updating of the database
and reducing the waiting time of the users.

TECHNICAL GOALS
The following are the identified technical goals used for the
configuration of the network solution
 To analyze the business rules for configuring the routers and the
switches with the appropriate networking protocols to meet the
requirement.
 To develop a user interface for the users for connecting with the
information system and use authentication for securing the
resources of the network.

CONSTRAINTS
The following are the constraints identified for the development
of the network solution:
 Identification of the requirement of the users using the network
and resources residing the data center network
 The technical skills of the network developer for configuring the
routers and the other network devices according to the
business rules.

TOPOLOGY
 Mesh topology is followed for the development of the network for
increasing the redundancy of the network and creation of
duplicate link such that if one of the link fails then the user can
reach the network devices.

TRADEOFFS
The following are thee identified tradeoffs that are used for the achievement
of the goals and objectives of the organization and are given below:
 To create a virtual server for balancing the loads and utilize the resources
of the physical servers
 To configure the router with MPL for enabling transferring of VOIP data
packets in the network and reduce the cost of the network.
