INTRODUCTION
An advancement of technology that has reached its highest peak of development, especially
in making easier for organization. The report is mainly focused on the network design and
development of university campus. It include the different factors such as integration, security,
adaptability and resilience whereas installing network in the ABC institution riles on the specific
budget.
The report will describe about the brief description related network and identifying software
as well as hardware requirements. Furthermore, it will determine the different network devices to
OSI layers and also highlighting the each function of devices.
Proposal description and requirements
The proposal is based on the data communication network to server with the educational
system. It will be designing the purposed network in order to achieve the specific enterprise/
operational objectives.
Furthermore, it will be describing the secure service after designing the network, providing the
secure administrative computing service. It will be designed to be functionally and physically
isolated from the access by users (Datukun, 2018 ). In network configuration, there are different
LAN in the ABC institution, but much of hardware equipment’s is out of date. Many other LAN
are becoming incompatible with each other and established the connection with wide network.
Requirements
 The campus consists of four different blocks with different three colleges.
 The first building block will have to support 100 machines each for campus.
Furthermore, it will identify the capacity of providing the better wireless communication
through hardware devices at given time.
 Each and every blocks within campus that will established the interconnection between
each other. Afterwards, it consider the effective machine as workplace (Ding, Feng and
Zhang, 2017).
 The CEO and chief technical officer will be located on the four different blocks, which
require the secure wireless access. In some situation, it will require the secure wireless
connection for each blocks.

 It will be set up the house for server room with mail, web server, FTP together with
corporate firewall system. Afterwards, it also providing the better firewall system to edge
for internet and braches of each buildings.
Assumption made on the connection between main site and different blocks
 A Large number of heavy data transfer that will take place between the main site and
different block of campus.
 A branch office building is located closely to main head office. Thus, it takes limited cost
for having the least line connection between different blocks.
 In some situation, there will be low data transfer taking place between two different
blocks. Therefore, they have established the permanent virtual circuit connection through
different frames.
 Network engineer is preferred to use leased line in which established the connection with
main site. In this way, there are large amount of heavy data transfer between sites. It
occurs the two interface that will be used up in gateway router.
Network design analysis
It will be required to follow the structured cabling approach in term of designing a
network. It is made up with large number of standardized element which is known as
subsystems. Furthermore, it will be categorised into multiple subsystem whereas ISP network
ends and connects to other user’s hardware devices (Feng and et.al., 2018). There are several
equipment and other part of network that serve the client inside the building block. Horizontal
cabling in the network design which are made up 100 Mb/s Ethernet cables which easily join the
wall sockets.
In this section, it analysis the depth study about the set of university campus network data
of both node, establishing a strong link. The internet access was centralised and each department
handled its own network, server management. The campus network design topologies are
meeting the specific consumer goals for availability and performance by other bandwidth
domain, redundancy and linked with the multiple way for workstations to reach the router for
off-net communication (Kuliesius and Dangovas, 2016). The core server as backbone of entire
network, which are established the connection with different devices such as routers. In order to
maintain the high capacity router and expected to be very resilient.

It will be identified the multiple hardware devices in which help for transmitting a large amount
of data from one department to another. The core devices such as Routers, Switches and Servers
that are high capacity and expected to manage the data or information. The distribution layer
aggregates node from easily access layers, protecting the high core catalyst 3750. Afterwards, it
will be used as core switches, connectivity between the ether-channels and core switches
(Kuliesius and Dangovas, 2016). The distribution that will connect with core by redundant links.
Various core switch as layer 3 devices and providing the high routing inter-distribution switch.
In this way, it has been developed the segmentation to group users into 4 different block at each
building, high availability at certain levels.
Figure 1 Network design
In this diagram, it is mainly focused on the high availability backbone in the network. It consists
of redundant link and identifying the failure detection inside the routing protocol. It will be
required four different blocks and need to be interconnected. Multiple hardware devices are used
for established the interconnection between each block. Afterwards, it help for transmitting a
single from one place to another.
Router/switch: In above network design, it consists the overall performance of router in
context of hardware performance. It allows for user to forecast instance when a router overload
not only by traffic volume but also identify the issues in the overall performance.
5

Sever: A network server provides various shared resources to the workstations. It may
include the powerful components that user workstations within each blocks. Each and every data
should be collected in the network server so that user can easily access the data within campus. It
consists of different servers such as FTP, Mail, Application, client and proxy servers.
Hardware and software analysis
Apart from the functional as well as non-functional requirements, it is important for
identifying the hardware needs within the network system. it will be undertaken all item which
used by ABC institution and furthermore, it has identified the essential network devices which
include switches, access point, printers and routers (Papamichail and et.al., 2019).
Hardware requirement:
 Cisco router 819HG-4G-IOX : 4 gigabit Ethernet, 1-serial port
 Switches for 24 ports
 Cisco Printers-PT
 Access point
 Cables: copper straight, co-axial : As per requirement within network system
Software requirement:
 Operating system for sever and VMs (Ubuntu 14.04.03 LTS)
 Used the Vmware ESXi version 5.5.0
 Access of public internet
 Memory per VM : 8GB
These are consideration of both hardware and software requirement, which mainly used for
performing the functionality within network system.
In additional, it will be understanding the network application in which providing the
better features of entire system. The chief technology officer will be analysed the traffic
application in the network, including the capture application session with multiple analyser
protocols (Tongkaw, 2019). These are usually used the large amount of bandwidth to the
internet. In this way, it help for user to access the application while monitoring the different
activities. in order expand the usage of network application but currently hindered by large
amount of bandwidth that are already available to internet.

Discuss about the network devices to OSI layers, which are located, highlight each function of
devices.
The open system interconnect model which is known as OSI model. It is one of oldest
networking over which many modern protocol applicable. This model consists of different layers
which are basically involved in the model such as physical, data link, transport, session,
application and presentation (Kuliesius and Dangovas, 2016). Each and every layer make use of
certain protocols which also performed the large number of function with respect to transfer of
data. In additional, it should be considered the certain devices which are performed the necessary
transmission processes. At last end, it also supporting for different application to perform
multiple task and enable this model to run process smoothly.
Physical layer: this type of layer is responsible for establishing physical connectivity with two
devices. It involves hubs, cable and repeater.
 Hubs are devices that commonly used into different segment. It also contained the
multiple input or output ports. Each and every signals at any input port which will made
at output port.
 Cables are generally used on the wired network that easily established the interconnection
with different devices. Some of cables such as coaxial, fibre cable and optical
 Repeaters are performed the functionality to regenerate digital signals by transmission
loss. At that point, it only amplifying the signals whereas reproduce the signal to original
quality.
Data Link layer: it is based on the transfer data hop by hop, which consists of different MAC
address. The data link layer are considering the different hardware devices such as Bridges,
modem and network interface card.
 Bridges: it has performed the significant functionality while providing the
interconnection with network through similar protocol. Afterwards, it has been
successfully transmitting the signals.
 Modem: it can be used to convert the digital signals and generated by computer into
analog signals.
Network layer: it is helping to create the routing table on the basis of input and generate the
output. Some of devices used in the network layer.
7

 Router: It will be used as device that routes data packets on the basis of IP address. It also
established the connection with LAN. It also supports for decision-making (Kuliesius and
Dangovas, 2016).
 Bridges: it is based on the router that applicable in the network device and work as
bridge. It can easily transmitted the protocol in the form of packets. It is the best way to
perform the functionality in the network system.
Transport layer: within network system, transport layer is responsible for maintaining end to end
communication. It should consists of different devices.
 Firewall: it is based on the system designed to help for preventing the unauthorised
access from private network. The functionality is that when easily filtering the packet
through proxy server.
 Gateways: it is consider as components that could be divided into different networks, use
for different protocols. Sometimes, gateway is performed the functionality to convert
protocol which will translate into another one.
Desired type of link between the campus and justify.
In network design, the redundant link connection will provide the better switched in each
block. Also added between two difference two core routers, switches as well as server (Kuliesius
and Dangovas, 2016). Main purpose of desirable link is that when it automatically goes down
still network components can interact with each other. In this way, it will concern about the link
between the network switches in order to avoid the problem or issue. STP protocol is also used in
the switches from different network, so as it active the link one link and blocked to another
mode. If in case network fails, the redundant link come into another active model from blocked
the model
In this way, it has been justified that backbone cabling is made of different
interconnection core node switch. Therefore, it can easily establishing the connection between
each block within campus. The primary reason is to use core 2 switch which providing the
redundancy and easily avoid the single point failure. Furthermore, this type of desired link will
perform the action through network device. It provide the facilities and service to share the
information in the form of packet. It also useful for manage the large amount of data when
network fails, it automatically activate the link for improving the data transmission within
network system.

From above discussion, it has summarized about the network design and development of
university campus. It also implementing the different parameters such as integration, security,
adaptability and resilience which help for maintaining the overall connection between multiple
devices in proper manner. Furthermore, it has summarised about the brief description related
network and identifying software as well as hardware requirements. It can be identified the
network devices to OSI layers and also highlighting the each function of devices.
