INTRODUCTION
Network is defined as the computer network which consist a group of systems that uses
the communication protocols to formulate digital interconnections for the motive of sharing
various resources which are provided on the network nodes (Network, 2021). Network Reference
Models provides the abstract structure regulation that communicates between networks. Internet
protocol version 6(IPV6) is the latest version of the internet protocol which gives a recognition
and locate various systems for networks and manages traffic across the internet. The following
report is made on the discussions of network reference models and IPV6 addressing to formulate
the networks.
MAIN BODY
Part 1: Create an approach for network address implementation and testing
Research Question-1: If layered network reference models are applied
to implementing the network of routers and switches and end
devices does this assist the network engineer?
OSI (Open Systems Interconnection) Model is a network reference model which is a
technical structure used to define the operations of different networking systems. It is featured as
technical functions into a sets of requirements and rules to support heterogeneous networks. It
consist 7 layers that are physical, data link, network, transport, session, presentation and
application layer (What is the OSI model?, 2021).
The Physical Layer: It is the lowest layer of OSI model which looks into communicating the raw
data in the form of various signals physically that transmits information from network devices to
1

a whole infrastructure. Data transmission such as bit synchronization and bit rate. Protocols used
here are Ethernet, Bluetooth, USB, IEEE802.11 and others (Physical layer, 2021).
 Data Link Layer: It is the second layer of OSI model, which looks into the data transfer
between the networks and handles the physical connections like switches. The raw data
which is received from physical layer is converted into data frames. Protocols used here
are PPP, ATM, Ethernet and others (Data link layer, 2021).
 Network Layer: It is the third layer of OSI model which arranges, manages and transmits
data across different networks. It searches the best physical path through which data can
be transmitted safely without any occurrence of error. Protocols used here are IP, ARP,
ICMP, IP-Sec and others (Network layer, 2021).
2

 Transport layer: It is the fourth layer of OSI model, it ensures that the data packets that
were converted by network layer is transported successfully. It rechecks after sending
data to the destination if any error arrives then it rectifies it for the smooth transportation.
Protocols include here are TCP, UDP and others (Transport layer, 2021).
 Session Layer: It is the fifth layer of OSI model, it handles sessions between software
servers to assist communication. It's function is to allow users of internet to browse for
3

some limited period of time. It controls the activities like authentication, opening, closing
and synchronizing data streams. It's protocols includes RPC, PPTP, SCP, SDP and others
(Session layer, 2021).
 Presentation Layer: It is the sixth layer of OSI model, It is responsible for the data
conversion between networks and the applications. Moreover, it handles character code
translations, encryption and decryption and data compression. It's protocols includes SSL,
TLS and others (Presentation layer, 2021).
4

 Application Layer: It is the last layer of OSI model which is responsible for the
interaction with an end user to the computer system, where access is possible between
applications and network services. Protocols used here are HTTP, FTP, DNS, SNMP,
TELNET and others (Application layer, 2021).

Perform a literature search relating to the research question above
(RQ1) and document the results of your relevant literature in a
bibliography.
Application and effectiveness of network reference model
Yes, this model will assist the network engineer because of their applications discussed
and how they can be applied in real time networking technologies (Fraihat, 2020). Because this
model supports the communication between the networks in formulation and implementation
among various networks so that data packets can be move safely across different clients and
servers. Applications of model are as follows:
 It is used to maintain different protocols for easy communication between various
networks across the world (Advantages of OSI model, 2019).
 It provides common platforms for software and hardware developers for communicating
through networks.
 It transforms large information into small data packets to understand in a easy manner.
 It converts complex activities into simpler elements (Advantages of OSI model, 2021).
 It provides standard interfaces for transferring information anywhere through network.
 It provides modular engineering in a comfortable way (Advantages of OSI model, 2020).
 It has accelerated the evolution.
 Learning and teaching is simpler due to network reference model (Advantages of OSI
model, 2021).
Write a review of the important literature you have identified in the
literature search in 1.1.

Formulate an approach for documenting, implementing and testing
the network addressing of the computer network in figure 1
show and describe this approach appropriately in your
assessment submission.
Working Flow:
All networks are between the server and the clients. Clients request the data to the server
and then server reverts back with the required information (How OSI model works?, 2021). But
this process is not so simple as it is looking, it consist various heterogeneous networks, which are
to be supported to each other in term of compatibility. Computer system works on binary data
which is impossible for the humans to understand it's language. So to simplify this problem,
various protocols are created so that information could be passed on the required location. So the
8

flow of the network is first end user request the information to the server which directly goes to
the application layer. Then this request goes through all the layers and converting it to the binary
format for the computer system to understand the query. It finally reaches to the physical layer, it
reverts back in binary format and again went to the process till application layer in a normal
English language so that it can read by the end user and then finally application layer present the
information to the end user (How OSI model works?, 2021).
Rigorously justify the use of this approach for implementing and
testing the network addressing of the computer network in
figure 1 by writing a justification in the report.
Design Approach in context of networks:
It is defined as the process of designing something for example a network. It has five
stages empathize, define, ideate, prototype and test.
Empathize: It clarifies about the users that who will be the end user who is going to request
though client side (Design Approach, 2020).
Define: It assist in pointing out the user needs and constructing the same from the uppermost
layers.
Ideate: It helps in working on the requested information through several layers who are
converting the language and controlling the error (Design Approach, 2020).
Prototype: It provides the useful information out of raw data so that it can look presentable and
can be viewed in front of the end user.
Test: This is finally passing useful converted information to the end user that they were actually
requesting.

Justification:
Importance of design approach are that it assist in handling the networking challenges
faced by the network engineer, it supports in meeting the requirements of the data and
information asked by the client and moreover, it expands the learnings and knowledge of
network engineer in terms of network and models associated with it followed by the testing and
implementation of it (Design Approach, 2020).
CONCLUSION
It is concluded that the networks are important part in this world as everybody is
preferring online in doing their works, so it is necessary to understand the internal procedure of
the network by studying various network models and their applications applied to real world. So
this report is containing explanation of models and their merits and usage with design approach.
