Executive Summary
Holmes Institute is creating new campuses for the expansion of their organization. For the new campus
building, they want to design a network solution to provide communication and network access for the
students and the staff of the organization. They want their networks should consist of both wired and
wireless design. On investigating it is found that their building supports both wired and wireless
connectivity.
Introduction
As per their requirement, we have designed a network topology which supports:
• Wired and Wireless Networking
• Desktop conferencing
• Usual Business Applications
• Office productive Packages
In the following design, we have configured both LAN and WAN connection. WAN connection is used for
providing communication with the other building and Internet. LAN provides communication with the
network (Han, 2016).
Also, we have configured a separate router which connects the entire campus with the internet.
Type of Media Cable
In the given topology we have used two types of media:
1. Copper Cable
2. Fibre Optic
Copper Cable
• Copper Cable is used to connect devices in the LAN segments.
• Copper Cable is efficient and reliable to use within a single Network.
• Copper Cable Provide bandwidth up to 100Mbps.
• In this network topology, copper cable is used between router to switches and switches to the PCs.
Wireless Router also uses copper cable to provide wireless connectivity.
• Cost of copper cable is approximate $5 per meter.
2

Fibre Optic Cable:
• Fibre Optic Cable is used to connect devices which require fast and max package transmission.
• Fibre Optic Cable is expensive and hard to maintain so it used where the distance between Networks
devices are less.
• Fibre Optic Provide bandwidth of up to 10 Gbps.
• In this network topology, fibre is used between router to router and router to internet ( Sullenberger,
2016).
• Cost of fibre optic cable is approximate $20 per meter.
Network Topology and Design
Network Area
Router00(Default Gateway):
Default Gateway is the router that is directly connected with the internet i.e its interface provides internet
in the given network.
It's one interface is connected with the server area which provides services of web, email and DNS (Elfring,
2019).

Default Gateway router interface is default gateway address of every system.
Interface Connected With IP Address
Se2/0 Router 01 123.45.250.1
Fa0/0 Server Area 192.168.5.10
Server's Area:
Email Server: - Email is message transfer service from sender to recipient. Email is used to provide legal
communication in the organization. In this network design, email helps to provide legal information sharing
between staff and students which include attachment related to the academics (Han, 2015).
In the Email Server, we have configured two user User1 and User2.
DNS Server: Domain Name System, it used to bind IP address with its associating name. It is hard to remind
so many IP address. Name server help to resolve the name and redirect to the associate ip address.
Web Server: A web server is used to resolve requests access by the client for World Wide Web pages. Web
server uses HTTPs protocol to process a request from websites.

Router 01:
Router 01 is used as Point of Presence which connects the other network to the internet.
Router 01 also provide connectivity to the different departments includes:
• Student Services

Router 02: School of Information System
This router is configured for the School of Information System. This router provides a routing service to the
school of Information.
 Router consist of 4 interfaces i.e 2 are serial and 2 are gigEthernet.
 The serial interface is connected with the router 01 and router 03.
 The Ethernet ports are further connected with the student subnet and staff subnet of School of
Information System.
