Introduction
In this report within six individual buildings, a network architecture implementation will
be done which is considered as M2M solution. The solution will be consisting of secret internet
standard that will be shared among the different buildings. Within this report, the sharing of the
IP is identified as such as the network address sharing model in accordance with the requested
case study (Garay, Kiayias, & Leonardos, 2015). The number workstations that M2M solution is
consisting of is almost twelve hundred in total. The provided network diagram within the report
has provided a brief idea regarding the internet connectivity.

The organization has six different buildings to be accommodate 1200 host, therefore they
need to distribute their private internet protocol in different subnets. The M2M solution have a
private internet protocol 10.0.0.0, which is being distributed among their sites. However, from
the above figure it can be assumed that how they are connected to the internet and their inter-
networking topology. Consequently, the following subnet calculation is prepared for M2M
solution, which is being assign to each site of this organization.

Task 1. B. Explanation
The main challenge in accommodating 1,024 hosts in a site is broadcasting in this
network. A broadcasting is technique of sending data packet though all the host in a network, if
any network having any broadcasting issue than it might be causes a rollover. However, if any
network having more than 1,022 hosts in a network, where require hosts per site is 1,024 then it
also deal with wastages of internet protocol issue.
Task 2. A. Communication protocol & Role of network analyzers
Communication protocols are required to provide end to end reliable data transmission. A
commutation protocol can be define as a set of rule that responsible to provided secure and
reliable data transmission (Chaubey et al., 2015). The M2M solution has around 1200 has in their
six building. Consequently, they have to utilize suitable systems for network devices to
recognize and additionally make the association between each other. These protocols are
likewise in charge of arranging decides that can determine how the information acquired from
network devices and additionally sent over the system. Consequently, the communication
protocol component likewise valuable to improve the execution of the system by message
verification as well as data compression.
As per the M2M solution networking infrastructure, design directing conventions
additionally required distinguishing different switches in the system. The router is assignment
with a routing protocol for utilized as a part of the switches to deal with the pathway between
sources to destination (Garay, Kiayias & Leonardos, 2015). There are few well-known routings
protocols are BGP, EIGRP and also OSPF. Through, the M2M solution it can execute the OSPF

protocol for their association to manage private systems administration locales with a center
switch, as appeared in the above figure 1.
The network protocol analyzer can be an instrument or programming that measure the
system execution by some system parameters. Moreover, the M2M arrangement has presented
six distinct destinations that can be associated with the web, hence they need to utilize an
examination device to check vulnerability and performance as well (Namesh & Ramakrishnan,
2015).
Figure 2: ZVA40 vector network analyzer
(Source: Duchêne et al., 2017, pp-13)
The network analyzer programming likewise compresses crude information into
something that sounds good to a client, who is insufficient shrewd with network administration

10TCP/IP NETWORKING
component. This interpretive apparatus can give outline information of the mistake from any
view of the application layer (Williams & Yumerefendi, 2017). For instance, if the M2M
arrangement is having some inconvenience like DOS attack or flooding, at that point they have
to channel in which have or where an unapproved get to endeavor. In that circumstance, they
should utilize the Wireshark organize analyzer device to channel that host or malignant client.

Task 2. B. Network analyzer tools
Benefits and Usability
The network analysers are used to analyse traffic all over the network of M2M solution.
There are two type of network analysers are available in the market such as a hardware device to
tracer the bandwidth, signal strength etc. as well as a software for data packets analysis.
Therefore, according to their category they have different specific functionality and features as
well (Segata et al., 2014). Consequently, a hardware device is ZVA40 vector network analyser
and Wireshark packet capturing tool is required in M2M solution to check their functionality.
A network protocol analyser like Wireshark offers many advantages that make it
engaging for regular utilize in most of the organization. The Wireshark network traffic analyser
can be utilized more than one hundred of network protocol. It can store the captured transmitted
data for offline or live examination, where the organization can filter out vital information
(Chaubey et al., 2015). It has been expected that Wireshark is very much compatible with Linux,
NetBSD, Windows, Solaris, and FreeBSD.
The hardware tool is being utilized in M2M solution is vector network analyser ZVA40
can measure the network traffic by watching a few parameters. For example, an order is a
measure of how well a coupler can isolate signals moving the diverse way (Burns et al., 2016).
Therefore, VAN is use to test the following component of M2M solution network infrastructure

radio wires, RF switch, couplers, channel, links, and in addition intensifiers. It also helps the
organization to increase the system uptime by utilizing its auto error correction methodology.

Recommendation
In this report the M2M solution have a private network 10.0.0.0 which is being divided
among six, hence after examinations their prerequisite it can be expected that they require
hardware device and software both can help for their organization. Subsequently, as expressed in
over the Rohde and Schwarz ZVL6 Vector Network Analyser is suggested equipment gadget
that can give a propel error correcting component. In any case, the equipment related issues are
measured by the Rohde and Schwarz ZVL6 Vector Network Analyser, aside from that a network
analyser programming Wireshark is required for inspect their internal network and access of the
outside of their network as well.
Conclusion
This report incorporates all network infrastructure related answers for the M2M
arrangement. The M2M arrangement needs to build up another system framework which is
totally characterized in this report. The system outline demonstrates the helpful tending to
answer for the M2M arrangement, which is being actualized for their locales. This association
likewise needs to think about their strategies for upgrading, which is characterized as system
analyzer device. In this report two different type of network analysis solution was recommended.
However, both of these devices are essential for the M2M solution. The purpose for the need of
that gadget likewise characterized in this report, which encourages the M2M solution for better
get it. Be that as it may, from this above examination and created tending to the arrangement, it
