3DATA COMMUNICATION AND NETWORKS
1. Introduction:
Data communication denotes exchange of data between receiver and source. Data network is
the network of digital communication allowing nodes in sharing resources.
The following report is prepared to recognize freeware tool monitoring complete network
and showing a status of every computer in the network. Then a freeware tool is identified for Wi-Fi
scanning, performance and QoS evaluation tool.
2. Justification of tool choice:
Here how this tool fits with necessities in every section.
2.1. Scenario 1:
For the given scenario Oracle VM VirtualBox is chosen to be the most appropriate one. This
is a free virtual manager of a machine, mainly from Sun and developed and available from Oracle. In
many cases controlling virtual machines is a hassle and expensive. A new version of the software
has been providing excessive features and wide support for various platforms and systems1. This
included Linux (2.4 and 2.6), Server 2003, Windows 7, Windows NT, Open BSD and plus Solaris.
Further, it supports OS/2. This comprises of an X86 virtualization package of software and working
as advertised.

2.1.1. Installation:
 Firstly one of the mirrors by distribution in /etc/apt/sources.lst is added.
 Then, public key and register are downloaded with apt-key for verification of a signature.
 Lastly, VirtualBox gets installed.
2.1.2. Exploring the features:
It is helpful for monitoring networks because of its supported guest operating systems and
different platforms it has been running on. Different network problems are detected through packet
logging at the host or guest side 2. Using built-in capacity of the tool create pcap filed supplies more
helpful information. This is because it contains a log of every packet sent and received by a guest.
2.2. Scenario 2:
For the present scenario, Wireshark is chosen to be appropriate. It comprises of huge user
communities and consistent improvements 3.

8. Finishing installation.
2.2.2. Exploring the features:
Currently is the foremost and broadly used analyzer of network protocol. It is helpful to view
what has been going on within the network at a microscopic level 4. It is the de jure standard around
all kinds of enterprises. It is beneficial to assess and troubleshoot interference, performance and
placement of Wi-Fi performance.
2.3. Scenario 3:
For the given situation OMNeT++ is chosen. It is modular and a component-based
simulation tool and library used to create network simulators.
2.3.1. Installation:

Manual installation includes the following steps.
 Downloading INET sources.
 Unpacking it to directory of the choice: tar xvfz inet-<version>.tgz
 Starting OMNet++ IDE and importing project through a file, import and existing projects
respectively to the workspace.
 A project called INET appears.
 Then the “project” is “build”.
2.3.2. Exploring the features:
To monitor networks the tool includes a broader sense of wired and wireless communication
networks. On-chip networks and queuing networks are also considered here 5. Moreover, it provides
domain-specific functionalities like ad-hoc wireless networks, sensor networks, performance
modeling, Internet protocols, photonic networks and many more.

Tools Discussion on its needed features
Oracle VM
VirtualBox
Here the networking is very powerful.
Networking in VirtualBox is extremely powerful. Network Interface
Controllers has been operating according to physical networking of the hosts.
The primary modes are described hereafter.
NAT networking:
Here guests sit on private LAN, VirtualBox has been acting as DHCP
server and the engine translates needed addresses.
Bridged Networking:

13DATA COMMUNICATION AND NETWORKS
The VirtualBox bridges to host network and good for server guests or
clients. It also consumes the IP addresses 6.
Internal networking:
Here guests see other guests under similar internal network. However,
hosts cannot fetch internal network. Moreover, it functions even when the host
gets disconnected.
Host-only networking:
The VirtualBox generates a private internal network for host and
guests. The host sees new software NIC. It also delivers a DHCP server.
Wireshark It can be distributed across the network. It covers every network areas
because of its open-source nature. It is configured for meeting particular needs.
For using Wireshark, the network target computers need to have Network
Interface Controller, with a promiscuous mode and about sixty megabytes of
disk space 7.
Further, CPU of the target computer requires having a minimal speed
of about 400 MHz. It can read live data from serial SLIP and pp, 802.11
wireless local area networks, token ring, Ethernet and fibre-distributed data

interface (FDDI) supported on Linux through lipbcap versions.
OMNeT++ One of the primary simulation frameworks for OMNet needed in the
current scenario is INET Framework. It is a standard protocol model library of
the tool. It consists of models for Internet stack like TCP, UDP, IPv4, IPv6,
and others 8. This also includes wired and wireless link layer protocols like
Ethernet, PPP. These are meant to support mobility, MPLS with LDP,
DiffServ, RSVP-TE signaling, MANET protocols and others.
RINASim is another stand-alone framework for OMNeT++. The
Recursive InterNetwork Architecture (RINA) touches and codifies all sections
of communication under computer network. The primary aim has been
providing a community with trusted and updated tools. This is to simulate
RINA-based computer networks regarding educational and scientific purposes.
This at its present state denotes an entirely working implementation of
simulation scenario for RINA9.
Castalia is another simulator for the WSN or Wireless Sensor
Networks, BAN or Body Area Networks. This also includes networks of low-
