Contextual Analysis Plan

Contextual Analysis Plan
To assess the adequacy of the proposed plan, a contextual analysis is utilized. An arrangement of parallel FIR channels with 16 coefficients is
considered. The information and coefficients are quantized with 8 bits. The channel yield is quantized with 18 bits. For the check channels r_i , since
the data is the entirety of a few inputs p_j , the information bit–width is reached out to 10 bits. A little limit is utilized as a part of the examinations
such that mistakes littler than the limit are not considered slips. As clarified in Segment III, no rationale sharing was utilized as a part of the
calculations in the encoder and decoder rationale to stay away from slips on them from engendering to the yield. Two setups are considered. The first

All things considered, the relative number of included check channels (n–k)/n is littler. At the point when analyzed with the math code strategy
proposed in [7], the reserve funds are littler yet huge going from 11% to 40%. Once more, bigger funds are gotten for the second arrangement. In
outline, the aftereffects of this contextual investigation affirm that the proposed plan can decrease the execution cost essentially analyzed with the
TMR and gives additionally decreases when contrasted and different routines, for example, that in [7]. As talked about some time recently, the
diminishments are bigger when the quantity of channels is extensive. The second assessment is to survey the adequacy of the plan to right blunders. To
that end, issue infusion tests have been led. Specifically, lapses have been arbitrarily embedded in the coefficients and inputs of the channels. In all
cases, single slips were distinguished and adjusted. Altogether, 8000 lapses for inputs and 8000 mistakes for channel coefficients were embedded in the

Chapter 5 Network Layers Questions 3, 5, 8
Chapter 5: Questions 3,4, and 8
9/29/2012
3. What are the parts of TCP/IP and what do they do? Who is the primary user of TCP/IP?
TCP/IP has two parts. TCP is the transport layer protocol that links the application layer to the network layer. It performs segmenting: breaking the
data into smaller PDUs called segments, numbering them, ensuring each segment is reliably delivered, and putting them in the proper order at the
destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the intervening computers through
which the message passes; it is IP that routes the message to the final destination. The TCP software needs to be active only at the sender and the
receiver, because TCP ... Show more content on Helpwriting.net ...
Network layer addresses and application layer addresses go hand in hand, so the same standards group usually assigns both (e.g., www.indiana.edu at
the application layer means 129.79.78.4 at the network layer). It is possible to have several application layer addresses for the same computer.
8. What is a subnet mask? A subnet allows the flow of a network traffic between hosts to be segregated based on a network configuration. The most
recognizeable aspect of subnetting is the subnet mask. Like IP addresses , a subnet mask contains 4 bytes (32 bits)and is often written using the same
"dotted–decimal" notation. For example, a very common subnet mask in its binary representation 11111111 11111111 11111111 00000000 is typically
shown in the equivalent, more readable form 255.255.255.0 A subnet mask neither works like anIP address, nor does it exist independently from them.
Instead, subnet masks accompany an IP address and the two values work together. Applying the subnet mask to an IP address splits the address into
two parts, an "extended network address" and a host address. For a subnet mask to be valid, its left most bits must be set to '1 '. For example,
00000000 00000000 00000000 00000000 is an invalid subnet mask because the leftmost bit is set to '0 '. Conversely, the rightmost bits in a valid
subnet mask must

Installing Windows Server 2012 Machine
GOAL
The main purpose of this lab is to install and configure services such as Active Directory, DNS and DHCP on the Windows Server 2012 machine.
Also the DNS and DHCP services were monitored with the help of a monitoring system like OpsviewAtom and Windows Performance Monitor. The
role of DHCP is to make sure that clients (Windows 7) can obtain anIP address whereas that of DNS is to make sure that they can access websites
within the domain.
The steps regarding AD, DNS and DHCP were a refresher as it was covered in a previous class. The installation and configuration of Microsoft
Baseline Security Analyzer and Performance monitor was new which needed some research and understanding.
PROCEDURAL AND INFORMATIONAL DOCUMENTATION
The first activity of the lab is to install Windows Server 2012 Datacenter. The steps involve using VMWare's Vsphere and the .iso image of windows
server that is already been installed. The steps for setting up the OS on the VM are pretty straightforward. After the CD/DVD has been inserted the
installation process is followed and then Server can now be used.
The second activity involved the installation of DHCP on the Windows Server machine. This is done by Add the DHCP Server feature Option from
within the Server Manager, Add Roles and Features. After the installation is completed, the scope of the subnet is to be defined. Within the scope, the
allocated range of IP addresses is entered along with certain reservations (Windows 7 client) exceptions.

Structure Of Class A Address Essay
Class A Class A addresses are assigned to networks with a very large number of hosts. The high
–order bit in a class A address is always set to zero. The
next seven bits (completing the first octet) complete the network ID. The remaining 24 bits (the last three octets) represent the host ID. This allows
for 126 networks and 16,777,214 hosts per network. Figure 7.1 illustrates the structure of class A addresses. The range of IP addresses is 0 to 127.
FIGURE 7.1: Class A IP Addresses Class B Class B addresses are assigned to medium–sized to large–sized networks. The two high–order bits in a class
B address are always set to binary 1 0. The next 14 bits (completing the first two octets) complete the network ID. The remaining 16 bits (last two
octets) represent the host ID. This allows for 16,384 networks and 65,534 hosts per network. Figure 7.2 illustrates the structure of class B addresses.
The range of IP addresses is 128 to 191 FIGURE 7.2: Class B IP Addresses Class C Class C addresses are used for small networks. The three
high–order bits in a class C address are always set to binary 1 1 0. The next 21 bits (completing the first three octets) complete the network ID. The
remaining 8 bits (last octet) represent the host ID. This allows for 2,097,152 networks and 254 hosts per network. Figure 7.3 illustrates the structure of
class C addresses. The range of IP addresses is 192 to 223. FIGURE 7.3: Class C IP Addresses Class D Class D addresses are reserved for IP

In general, an IP address along with a port number forms a socket. Figure 3.10 shows the client–server relation with sockets.
In a client–server communication, a client initiates the communication process, whereas the server responds to incoming client requests. It should be
noted that a server typically starts before the client does, and waits for the client to request connections. Figure 3.11 shows the
Figure 3.10: Socket Concept interaction between a server and a client as a flowchart where every block in the flowchart has an important role in
the network connection. First, a server and client create a socket S. Then the server binds the socket S to a local address, which is optional for a
client. The server then listens to the incoming connection requests from clients to alert the TCP/IP machine of the willingness to accept connections.
The client now connects socket S to a foreign host. By this time, the server accepts the connection and receives a second socket NS. The server uses
this new socket NS whereas client uses socket S to read and write data by using sendto() and recv() calls until all data has been exchanged. Finally, the
server closes socket NS, the client

The Implementation Of A Ipsec Tunnel
To allow the regional offices to pass traffic securely a GRE IPsec tunnel will be created between offices. This will allow all data to be encrypted
prior to being sent out to the internet. This will prevent unauthorised reading or manipulation of sensitive data. The UK office will have two tunnels,
one to each branch office. In order for the remote branches to communicate with each other their traffic will pass through the head office. The initial
part of the configuration is the addition of GRE tunnels between the offices. These will be based on /30 subnets within the 192.168.0.0 range.
Ethernet allows packets of up to 1500 bytes to pass through it. As the GRE header adds an additional overhead to each packet Cisco recommend
configuring the Maximum Transmission Unit (MTU) to 1400 bytes. An additional aid is to add the TCP adjust–mss 1360 which keep the TCP SYN
packets small enough to pass across the tunnel.
Figure 5 10 GRE Tunnels
The tunnel state was verified with the " show ip interface brief | inc Tu" Figure 5 11 GRE Tunnel Status
With the tunnels in an "up up" state the ISAKMP and IPSec configuration can be added. In order for IPSec communication to exist between the sites it
must complete a 3 step process.
Identify interesting traffic. This is done by the configuration of an extended ACL which will tell the IPSec to encrypt anything matching the permit

Transmission Control Protocol (TCP):
Transmission Control Protocol and Internet Protocol are two distinct computer network protocols. A protocol is an agreed–upon set of procedures and
rules. When two computers follow the same protocols the same set of rules they can understand each other and exchange data. Transmission Control
Protocol and Internet Protocol are so commonly used together, however, that Transmission Control Protocol and Internet Protocol has become standard
terminology for referring to this suite of protocols.
Transmission Control Protocol divides a message or file into packets that are transmitted through the internet and then re–assembled when they reach
their destination. Internet Protocol is responsible for the address of each packet so it is sent into the correct destination.
Advantages of (TCP) :
A network is just a bunch of computers with wires running between them. Properly implemented, a network is a system that provides its clients with
unique capabilities, above and beyond what the individual machines and their software applications can provide.
Most of the benefits of networking can be divided into two generic categories connectivity and sharing, and Hardware sharing, Internet Access, Internet

3.) What are the parts of TCP/IP and what do they do? Who is the primary user of TCP/IP?
TCP/IP is the transport/network layer protocol we use on the internet. Many BN'S, MAN's and WAN's rely on it. This is because it is relatively
efficient, and transmission has few errors. Any errors that are found, are checked and so large files can be sent even in the most unsafe network and
the data will still be unchanged. TCP/IP is very compatible with a number of data link protocols as well.
The two parts of the TCP/IP are the: Transport Layer Protocol and the Network Layer Protocol aka TCP and IP. TCP is what links the application
layer to the network layer. It also helps by segmenting the data, by breaking them down ... Show more content on Helpwriting.net ...
* The network layer address is used primarily by network layer software. A web address is translated into anIP address via a network layer protocol (in
this case, IP used on the internet.) The IP address translated can be 4 bytes long with IPv4 (e.g., 129.79.127.4), which is today's standard. The process
can be compared to looking up a name in a find book to find their phone number. * When it comes to routing, the network layer; is what finds the
data link layer address of the next corresponding computer that the message has to be sent to. The easiest way to interpret this, is to look at it with
Ethernet software. For example, if the data link layer is run using Ethernet, the network layer IP address would have to be translated into an Ethernet
address so they can match and understand each other. Ethernet addresses are six bytes in length. The following table below, shows a better picture of
the differences in software and addresses amongst the three. (Fitzgerald, 158)

Case 10.1.3 Essay
2.10.1.5.2 RIP Timers RIP has four basic timers
1)Update Timer – indicates how regularly the router will send out a routing table update.
2)Invalid Timer – indicates how long a route will remain in a routing table before being marked as invalid, if no new updates are heard about this
route. The invalid timer will be reset if an update is received for that fussy route before the timer expires. A route marked as invalid is not
immediately removed from the routing table. Instead, the route is marked with a metric of 16, indicating it is unreachable, and placed in a hold–down
state.
3)Hold–down Timer – indicates how long RIP will "suppress" a route that it has placed in a hold–down state. RIP will not accept any new updates for
routes ... Show more content on Helpwriting.net ...
The request asks that a router send all or part of its routing table. The response can be a spontaneous regular routing update or a reply to a request.
Responses contain routing table entries.
Version number– Specified the RIP version used.
Zero– This field is not actually used by RFC 1058 RIP it was added solely to provide backward compatibility with varieties of RIP. Its name comes
from its defaulted value, zero.
Address–family identifier (AFI) – Specifies the address family used. RIP is created to carry routing information for a number of different protocols.
Each entry has an address family identifier to indicate the type of address being specified. The AFI for IP is 2.
Address–Specifies the IP address for the entry.
Metric– This Indicates how many internetwork hops or routers have been negotiated in the excursion to the destination. This value is between 1 and

tion. Therefore, Man–In–The–Middle (MITM) attacks that need to target specic IP address(es) and other types of attacks against node 's privacy can

In this paper a new version of MTM6D (MTM6D II) is presented to resolve the above shortcomings. Further– more, a suggestion is proposed to prevent
black hole at– tacks, as a part of DoS attacks (in which a compromised router on the path between two hosts discards packets instead of forwarding
them) and bandwidth depletion
DDoS attacks (that only need the subnet ID instead of the exact IPv6 address of a target). A method is also presented to recover the communication after
rebooting a host.
The proposed method (MTM6D II) is designed to meet the below requirements:

As the re– sult, the proposed method does not depend on a specic algorithm or key size for encryption, authentication, and key distribution. This
portability feature helps us to implement this method for dierent applications like small low–power Internet of Things (IoT) devices. For example, the
choice of cryptographic algorithms is left to negotiation steps of IKEv2 to select an algorithm that both parties support.
The remainder of this paper is organized as follows.
Over the next two sections, an overview of the related work and some details of Mobile IPv6 are provided.
Then the proposed solution and results of testing with a prototype implementation are presented. Finally, some conclusions are oered and the future
work is discussed.

Some cloud–based defense methods were presented in [8], [9], and [10] for Internet services against DDoS attacks. These solutions were based on
performing se– lective server replication and intelligent client reassign– ment, where the victimized servers were turned into moving targets in order to

Company Overview In this plan, I will describe the process of creating a WAN for ACME Manufacturing. ACME Manufacturing has six buildings in
different locations that need to be on the same network. Headquarters and the other remote locations of ACME Manufacturing share the need for
constant communication with each other. Atlanta, Georgia, is the home of ACME manufacturing where they have another building across the street,
their engineering facility. The other locations are in Phoenix, Chicago, New York, and China.

Some of the benefits of VOIP are, enhanced productivity, reduction in telecommunication costs, and makes any phone system highly flexible. VOIP
increases productivity and provides useful features and capabilities that a normal phone system cannot offer.
VLAN/IP Address Building a VLAN for ACME manufacturing one would think a Class B would be the choice, but with Classless Interdomain
Routing (CIDR), it will not be necessary. "CIDR eliminates the traditional concept of class A, B, and C network and with CIDR, the addresses that
were wasted for the class A and B networks are reclaimed and redistributed for use later" (Regan, 2004). Dividing the network into smaller
subnetworks, which would be the six builds that ACME occupies, will enhance network performance. Each subnetwork will have resources and devices
available to its users and eventually freeing broadcast traffic in the network.
Equipment for the Network Designing a WAN, the network equipment needs special considerations. The following list is the recommended equipment
best suited for ACME manufacturing: * Mainframe computers * Switches and routers * Telephony system * Firewalls * Wireless equipment
The main component of each of ACME manufacturing's buildings are the mainframes computers. The mainframe in the headquarters building will
control the connections of the different networks, in turn connecting all networks, routers, and firewalls to the mainframe at the

Why Packet Switched Networks Are Used For Data...
1.Discuss why packet switched networks are used for data communication instead of circuit switched? Ans: Packet switched systems utilize a
customary technique by exchanging each single packet to the destination address at nonstop interims however the greatest result for every interim
will be the same one, this will include a few different routes or paths . This is one method to ensure the nature of the methodology by permitting one
and only single packet at a solitary interim to the destination address. In another way it can be seen as moving information in divided little blocks to
the destination address which are again assembled in a exact sequence to produce a message. Circuit exchanged systems is the methodology of
association in the middle of two devoted hubs permitting full data transfer capacity of the channels to stay joined all through the correspondence n
session. It guarantees a solid association territory that aides in non transformation on the other hand information spilling control. It is by and large
utilized as a part of open exchanged phone system (PSTN), circuit exchanged information (CSD) and rapid –circuit exchanged information (HSCSD),
Optical mesh and Datakit. The methodology of transmitting data between two hubs through a system is finished by utilizing Packet exchanged and
Circuit exchanged, which are noteworthy in conveying the data to their comparing destinations. On account of circuit exchanged the correspondence

In its basic form, a typical RFID system has two major components, a reader and tags, as shown in Figure 3.1. These tags are made from a tiny chip,
also called an integrated circuit (IC), that is connected to an antenna that can be built into many different kinds of tags including apparel hang tags,
labels, and security tags, as well as a wide variety of industrial asset tags. The tag chip contains the product's electronic product code (EPC) and other
variable information so that it can be read and tracked by RFID readers anywhere(Impinj 2015).
An RFID reader is a network connected device (fixed or mobile) with an antenna that sends power as well as commands to the tags. The RFID reader
acts like an access point for RFID tagged items so that the tags' data can be made available to business applications.

Plan for Migration from Windows to Linux
The transition from Windows to Linux can be long and take months to achieve, the moving of data setting the installations of the servers and clients
is time consuming and need professionals to handle it, however the transition is more than worth it. A good transition to take place would require
extensive planning of resources, time and expertise. The best approach to deal with migrate from Windows to Linux is gradual, one department after
another. The service of servers is the most critical phase to start with. A typical office uses shared resources to maximize on the resource hence it is
critical to start with the services that are shared the most and change those first. Printing, Storage and application servers are some of the critical areas
that any organization's IT want to see go as smooth as possible. Linux can be configured from installation to be a server or just a regular desktop client.
Once the servers have been installed in place then the clients that are going to be pulling the resources from it can be installed and integrated gradually
to avoid disruption of services to the workers.

subnet design enables administrators to quickly locate computers by IP address by building floor and room, and whether the computer is a server, a

The Admissions Office and Classroom directly above the Admissions office is over 300 feet (the Ethernet limit) from the server room and a
diagonal pull through the ceiling (258 feet plus a 30 foot drop best case) could be complicated by power line interference and possible obstructions),
so these two rooms will require fiber optic cabling rather than CAT 6 UTP.
Wireless media access will be protected using WPA2 security with AES 256 encryption and a pre–shared key to prevent eaves dropping.
The network will use the Hewlett Packard Procurve switches because of their high performance, low cost relative to other brands (such as Cisco)
and their lifetime warranty. The Hewlett Packard E5406zl switches are can support up to 144 gigabit network connections (10/100/1000baseT

You can very quickly tell whether you have built a poor connector on either end, or if you do not have a solid connection to the switching hardware
device. On the cost side, I would contend that the support for future growth in bandwidth and error minimization should easily offset the cost difference.
On the distribution layer, I would suggest using V–LAN devices that are interconnected. By using V–LAN devices you can easily provision separate
LANs on each floor while still supporting any network changes in the future. V–LAN devices can provide both switching and routing capabilities
because they act as both layer–2 and layer–3 devices. This is a huge advantage in the fact that you can provision separate subnets for each LAN while
still allowing certain IPs the ability to communicate to either subnet. This is setup in the router side of the V–LAN software. The V–LAN also easily
supports the adding of more user machines (with enough fiber runs established) electronically. Opponents will say that V–LANs required the added
expenses of more knowledge and management than the more standard design of separate physical switches and routers. I agree, but we have to keep in
mind that this is a new construction process. We want to ensure that we have appropriate hardware to support future growth potential whether it is in

Our project focuses on the analysis of a network protocol and how it works. The network layer Oliveir Bonaventure explains as "providing a
connection–less service. It identifies each (interface of a) host by using an IP address. "[4] Mainly this layer passes information between layers and
provides a way to address them. The main goal to enable hosts to send packets of information containing up to 64 KB. An issue arises when
information doesn't deliver to the correct destination. This issue is because there is no actual guarantee of the delivery. Also, the detection of errors
isn't a guarantee during the transmission process. There is a common analogy for the network layer. "It's like a worldwide postal service providing an

The first of these is the source port which is 16 bits of information that identifies the source of the data. Compared to the source port, the destination
port also holds 16 bits of information. The only difference is the destination port holds information about the data's destination. These two ports are
what are responsible for building the pathway for the data. Following these is the length parameter which defines how large the UDP packet is going
to be. It stores a max of 16 bits but also has a min of 8 bits. In IPv6 if the size is greater than a 16 bit max the length is to be set to 0, this process is a
jumbogram. In IPv4 the checksum value is optional, which means in the case there's no checksum value, that value is set to 0 as well as all the bits
are set to 0. [3] IPv6 the checksum is mandatory. "The checksum is the 16–bit one's complement of the one's complement sum of a pseudo header of
information from the IP header, the UDP header, and the data. This header is padded with zero octets at the end (if necessary) to make a multiple of
two octets" [5]. IPV6's checksum has a modification in the calculation due to the increase in the header size.
To show UDP is a simple protocol, compare it to its brother TCP. When compared, UDP has less functionality and overhead which results in decreased
reliability.

Obtain a wireless residential gateway from your instructor, or you can utilize your own. If the contrivance has external antennas, ascertain they are
situated vertically; and if they utilize a screw–in connector, ascertain the antennas are finger–tight and do not fall to the horizontal position again.
Never turn on a wireless contrivance equipped with external antennas without first having them connected and tightened up. The absence of a felicitous
load at the output of the transmitter can damage the circuit. In integration, despite the very low power levels of most WLAN contrivances, you are
exhorted to never touch the antennas when the contrivance is turned on as this may represent a health peril. Connect an RJ–45 Ethernet crossover
patch cable to one of the switch ports in the back of the contrivance. Note that one port is disunited from the others and is customarily marked "WAN."
Do not connect anything to the WAN port. Plug the other terminus of the cable into an Ethernet port on your computer. Plug in the puissance adapter

How Modbus Is A Type Of Communication
Modbus is a type of communication among many devices connected to the same network, for example a system that measures temperature and
humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in
supervisory control and data acquisition (SCADA) systems. [17]
In simple words, it can be explained as a method used for transmitting information over the lines between electronic devices. The device asks the
information is called the Modbus Master and the devices supply information is Modbus Slaves. In a standard Modbus network, there is one Master
and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the... Show more content on

This number tells the slave which table to be accessed. It also decides whether to read from or write to the table.
3.2 Internet Protocol
The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a
host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.[18]
While data transferred in a network, is sent or received(for simple understanding, an e–mail note or a Web page), the message is divided into little
pieces called packets. Each of these packets includes both the sender 's internet address and also the receiver 's internet address. A packet is firstly
sent to a gateway computer which is the first station of the Internet. The gateway computer reads the destination address and forwards the packet to an
higher gateway which reads the destination address and transfer it over the internet until one gateway recognizes the packet as belonging to a computer
within its area or domain. The packet then is sent by gateway directly to the computer which address is specified.
3.2.1 Subnet
A subnet represents all the devices found at one location. It can be a building or the same local area network (LAN). If a company 's network are
divided into subnets that allows everyone to connect to the Internet with a single shared network address. If there is no

Week 4 B IP Subnetting Lab Essay
Introduction
Assignment
Develop a subnetting plan and implement it in the lab. Configure RIP as a routing protocol.
Conditions
NYEDGE1 is the hub router. The two remote office routers NYEDGE2 and NYWAN1 connect to NYEDGE1 through serial connections. Each router
has a locally attached Ethernet network.
The serial line data rates and DTE/DCE settings have already been configured on all three routers. You only need to assign theIP address to the
interfaces.
Notes
The routers are connected directly to each other in this lab and do not actually connect through any leased line services.

Task 1 – Create a subnet ... Show more content on Helpwriting.net ...
You are not encouraged to use this subnetwork because it specifies the wire address.
Nor should you use the last subnet, 192.50.6.224, because it is considered the major network broadcast address. Therefore you can only use subnets
32, 64, 96, 128, 160 and 192. With this design requirement, you only need to use five of the six usable subnetworks, leaving one for any additional
segments in the future. Likewise, for each subnet, you cannot use the first and last address. For example, subnet 192.50.1.32 extends all the way to
192.50.1.63. But you cannot use these two IP addresses (.32 and .63) because they are the wire and the broadcast addresses for this subnetwork. But
you can use any of the 30 IP addresses in between.
Task 3 – Configure the interfaces in each router Step 1: Configure Gi0/0, s0/0/0, and S0/0/1 for NYEDGE1.
Action:
