Enhance the Security and Performance of IP over Ethernet Networks by Reductio...CSCJournals
In this research, we investigate the weak link between two protocols, IP protocol and Ethernet protocol. IP over Ethernet network has become the major network used by Internet. In this network, still the data link layer performance and security problems not adequately addressed yet. The findings of this research lead us to propose a modification, by making a reduction on current naming architecture to improve the network performance and security. The proposed architecture will be evaluated by a theoretical analysis.
A DNS server is a server that manages the domain name system or DNS protocols, matching Internet domain names and IP addresses. The DNS server may also manage domain resolution services.
Here, I have designed a lab room using different PC and connected them using a Switch, and then connected them with the DNS server. I have used Server0 in PC0 and PC1. However, in PC2 and PC3 I have used Server1.

Abstract
In this report, the planning to design the network will be discussed and demonstrated in detail. The planning to design the network layout will be made according to the scenario given in the requirements. The plan will be implemented by the evaluation of the aspects that are important to design the network and other necessary things to design and implement the network. After implementing the network, the network will be tested by secure communication, WAN communication Channel, Wireless network, and PAN network. The troubleshooting of the network will also be discussed and elaborated in detail. The protocols used in this network will also be taken into consideration.
Introduction
Designing a network is not a simple task for someone. There are different phases to design the network. Each phase has a very important role to design the network. The first phase is to collect all the requirements to design the network. The second phase is to evaluate the requirements to make sure that either requirement is enough to design the network or not. After evaluating the requirements, the third phase is to implement all the aspects that are gathered in requirements. The fourth and last phase after implementing the network design is to optimize the network by performance.
Network Layout
The physical arrangement of the network is called network layout. The network layout of the given is scenario is shown below:
Diagram created using CISCO PACKET TRACER 7.3.0
Demonstration
This network consists of two different places one place is headquarter which is the main point of this network and another place is Therall which is the working point of this network.
Headquarter
In headquarter, the Executive office, R&D, Reception, Guest office, and accounting office’s host are connected with one switch. Twisted pair cable is used in this part of the network. Each device directly connected with the headquarter switch. 8P8C (Actually, RJ-45 is the more common term) jack is used in this part of the network and it is located in the reception area. Bus topology is used in this part of the network. (I think that what you have in your diagram is a bus-star hybrid. The switch is the bus, the individual cables to the hosts are the star)
Thrall
In Thrall Remote, the Engineering area, production area, and reception area’s host are connected with the switch. Twisted pair cable is used in this part of the network. Each device directly connected with the headquarter switch. 8P8C jack is used in this part of the network and it is located in the reception area. Bus topology is used in this part of the network.

Communication, and Connectors
Objectives:
During lab we explored Internet RFCs, RS-232 Communication data
format and Cables and Connectors
Results:
This lab was basically a research project to help us understand how
the Internet Standards are created and how to pick the correct
interface material that meets the requirements of any interface. Some
of the topics were also refresher information from other ECET classes
like the ASCII wave forms.
Conclusions:
After you design a system it’s critical to use the correct interface
mediums and material types that meet your requirements. Picking
materials that cover data rate or frequency values beyond your
requirement will have an adverse cost effect on your final design.
Keeping up with technology and standards is important in
engineering. Before you pick materials for your design, complete your
research to insure you take advantage of standards and material types
that meet your requirements but do not exceed them. Balance the
quality of these materials with your projects budget and you’ll be
successful.

ECET 375 Week 2 iLab Calculating Spectrum and Linear Filtering in
MatLab
Objectives
This lab is intended to explore signal spectrums and filtering
operations using MatLab. Running pre-written MatLab scripts and
altering these codes to perform specific tasks will be necessary to
develop the appropriate displays. Calculation of a signal spectrum
using the SigSpec.m file, and altering this file to display different
6. types of signals including Cosine, AM, and Square waves will help to
explore signal characteristics and display MatLab functionality. Using
a second per-written file (LinFiltering.m) and MatLab, displaying
how filtering can affect a signal, will be used to describe this process
and how the resulting signal changes.
Results
During the exploration of this lab, the MatLab program was used to
run specific functions containing the code necessary for appropriate
signal plotting. These plots were created for the cosine, the AM, the
square wave, using random information and breaking down a sound
file (.wav). For each of these signals a MatLab plot was acquired, and
used for analysis. Additionally, running the LinFiltering.m file in
MatLab allowed the explanation of filtering to be shown in a plot.
These plots were created for both the time and frequency domain, and
successfully showed how a filter can help contain a signal.
Conclusions
After the completion of this lab, the concepts included are starting to
make more sense. Realizing how powerful MatLab can be, and the
functions accomplished by it are astounding. Creating the signal plots,
being able to visually see the intended signals and then manipulating
these signals is a real asset in the learning process. Each signal has its
own characteristics and these characterstics can be contained, soften
the edges, by using different filtering techniques. These filters can
help remove unneeded data, showing the true signal behind it.

Objectives
The purpose of these lab procedures is to visually see how the Ping
and Traceroute Applications work. This will be done using WireShark
and a precaptured file “ecet-375RemotePingTracert.pcap”. The use of
IP and ICMP protocols in diagnostic testing will be accomplished by
writing the command in the DOS Prompt and captured in the
WireShark program (already done for us). This file will be analyzed,
depicting which packets do what and the time taken between specific
packets.
Results
During the exploration of this lab, the WireShark program was used
to analyze a pre-captured internet session. Examining the “Ping”
ofwww.iana.org is the basis of the first procedure. Determining which
packets are DNS query’s and which packets are DNS responses as
well as the actual IP address for this link is accomplished in the first
few steps. With the ICMP protocol, knowing that there are four
requests and four echo responses, these packets are found and
documented. Additionally, the times between request and reply are
found and recorded with the help of the “Set Time Reference
(Toggle)” within the WireShark program.
14. The next procedure, Traceroute, also deals with a Dos command of
“tracert” and is done on the same address of www.iana.org . The
packets that take care of the DNS query for an IP address for the site
are discovered and documented, as well as the number of HOPs
performed on the investigated trace. Similar to the “Ping” procedure,
the time between the requests and the error responses are discovered
using the “Set Time Reference (Toggle)” with 3 requests and
responses per HOP.
Conclusions
After completing this lab and seeing how these investigative tools can
help in the diagnostic of a communication network, it is realized the
importance of applications like these. In my profession I have used
the “PING” command to see if a specific computer in the domain is
“alive” and communicating. The Traceroute command is new and can
be just as useful. Using the Traceroute application to ensure
communications through all routers and switches is occurring and in a
timely fashion can prove to be very useful in discovering issues to
come.

in the Internet

Discussion:
TCP (Transport Control Protocol) and UDP (User Datagram Protocol)
operate at the Transport layer of the Internet Protocol Hierarchy. They
deliver information between Internet applications. To identify the
applications running on a host, Internet transport layer uses port
numbers, each a sixteen-bit number expressed as a decimal number
(e.g. 80). Each host interface on the Internet is uniquely identified by
an IP address, a 32-bit number usually expressed in dotted decimal
notation (e.g.192.168.1.45). TCP and UDP combine data from
multiple applications into a single outgoing connection at a source
host. This process is called multiplexing. These protocols, at a
destination host, separate data arriving at an incoming connection
destined for different applications. This process is called
demultiplexing. TCP is connection oriented and has many other
features geared towards providing reliable communication, flow
control and congestion control. UDP is connectionless and does not
have these features.
In this lab, you will analyze pre-captured Wireshark files to explore
features of TCP and UDP protocols and their differences.
