1.3 Definitions and Limitations
This design should increase operational efficiency and overall profitability based on return on investment (ROE) calculations.
Limitation could be in:–
–estimating and gathering more information about the existing network and applications
–The cost required to update the existing network to IP network.
–Applying mechanism to ensure that the service level agreement is met.

2. Analysis and specification
2.1 Initial condition
Channel 4 has two studios located in Sydney and Melbourne and four free to air television channels (channel4, C4forKids, WOW and QTV). In
addition, channel 4 has three types of video contents:–
InProd content is edited by Channel 4 and finished product is sent as SDI streams to be stored in the digital media center, via Studio Router.
ExProd content is provided to Channel4 on solid state media as a digitized video file. These files are stored in the Digital Media center until required.
Live Video Feed is live news and programs to broadcast directly to Australia.
The existing Studio Router takes SDI/ASI input and assign it to many outputs such as MPEG Encoder, Video output, Satellite Uplink or Digital Video
Network (DVN) to Media Hub.
There are three DVN that transfer MPEG Encoded videos either from Digital Media Center or live Video from a News Studio to the Media Hub
(Figure 1).

ENGINEERING MANUFACTURER Introduction: EngCo Company manufactures components for the oil and gas industry. It is a cross–discipline
engineering company, which combines electrical, mechanical and process engineering skills. The purpose of the company is to produce custom–made
components for large gas and oil companies across the globe. The company needs a design to set up their data network. A report is needed to be
written where the options for setting up their network will be outlined, including details of how all services will be provided. Task–1: Physical
Topology Diagram a)Chosen Topology:Network topologies are categorized into the following basic types: 1.Bus Topology 2.Star Topology 3.Ring
Topology 4.Mesh Topology Among them Star Topology is more suitable for this network. b)Explanation of Choosing Star Topology: In Bus
Topologyall computers are attached to a single cable. So if any of the connection breaks down, the entire network breaks down with it. It is difficult to
move and change since they are all link up together. It 's difficult to troubleshoot (justfortest.tripod.com, n.d.). In Ring topology, Data moves in a
one–way path only. It is expensive because multiple cables area needed and difficult to reconfigure. Simply not fault tolerant because a single cable
fault can bring down the whole network (justfortest.tripod.com, n.d.). In Star Topology, each computer is connected to a central point from a dedicated
cable. The central

Nt1310 Unit 3 Assignment 1 Network Layer
Core The core layer is the backbone layer of the network running at high speed switching, transferring large amounts of data and also handling the
requests of the distribution layer . This layer has high speed devices; the most implementations have layer 3 switches or high end routers. Its key
characteristics are: redundancy, fast transport of large amounts of data, high reliability and availability, low latency. The core layer should not do any
packet manipulation.
The distribution layer acts as a services and control border between the access and core layers. This layer is the place where routing and packet
manipulation, policy enforcement, access control are performed. The distribution also has high redundant connectivity, both toward the access layer
and also the core layer. In this section, layer 3 switches or routers are typically used. ... Show more content on Helpwriting.net ...
The purpose of the access layer is to grant user access to network resources; in my case mostly through wireless access points. The access layer's main
characteristics are: high availability, layer 2 switching, QoS, Power over Ethernet.
5.5.SERVERS
For a school the convenient server topology is a centralized server farm design . Due to this design the Network traffic enters and leaves the server
farm at a defined point which makes it easier to secure, filter, and if needed to prioritize traffic. The essential server types are the following for any
network.
The first server is the Domain controller which stores the users account information and responsible for authentications while also enforces security
policy due to the Active Directory Domain

Advantages And Disadvantages Of Repeaters
In order to accomplish each of the above tasks there can be various devices used for this purpose they are repeaters, bridges, switches, routers and
gateway. Each of these devices will be discussed below along with their advantages, disadvantages and specifications.
1.Repeaters are electronic devices that receive a single and modify it into higher level or power signal and then retransmit so it can travel or cover
longer distances hence in a way it regenerate, amplifies or reconstruct a signal. A repeater functions in OSI model at the physical layer and it is
transparent to all the protocols that are operating in the layers above the physical layer. As repeater cannot differentiate between noise and data hence
with data noise is also amplified. There are some advantages and disadvantages of repeaters:

How Sniffers works using Wire shark: References: wire shark website(network forensics.)
To comprehend the risk that sniffers show first requires understanding how sniffers work. The way in which sniffers work relies on upon the kind of
system. In a mutual media system, for example, a standard Ethernet, parcels sent along a system fragment travel all around along the wire. Any host
associated with a fragment is equipped for catching all sessions inside of that section. For instance,
Exhibit 1 portrays a sniffer–able host. It can catch any activity that experiences the system section, despite the specific neighbouring host or other
remote host to which that activity is foreordained. In different sorts of systems (e.g., token ring systems), sniffers are able just of References: wire

Examples Of Capstone Report On Casinos
Capstone Report IntroCapstone Report Introduction
The Casino world is a highly competitive, fast paced, growing section of the economy. Each established casino tries to gain the upper hand on other
casinos around it by having the best and most amenities for its guests. Examples of this are hotels attached to the casino, RV parks, gas stations,
restaurants, and golf courses. This project focused on one such casino and its strive to become a resort destination by buying a golf course right next to
their property, and the struggle of getting that golf course up and running as it applies to the IT world.
XYZ Casino is a mid–sized company with 250 employees. Their main location is just outside of a small coastal town called Florence in the State of
Oregon. XYZ originally has three restaurants, a 150–room hotel, and RV lot. XYZ Casino hopes to expand its operation to include an 18 hole Golf
Course near its property to help further its goal of becoming an all–inclusive Resort Destination. This Golf Course was Sand Dunes Golf Links located
right next to the XYZ Casino Property. With Management on board, they took their proposal to the stakeholders to ask for their permission to buy the
golf course and rebrand the Casino as a resort.
With the backing of the stakeholders, XYZ Casino bought the golf course and announced the rebranding of XYZ Casino to XYZ Casino & Resort.
Within hours of the announcement, management had requested the IT team to pull together and formalize

These factors will impact on the network costs, speed, infrastructure, and functionality. When designing this Local Area Network (LAN) for DesignIT,
there is also need to consider the network requirements. The network should integrate sound, video, synchronous, as well as asynchronous data. When
designing the LAN network, the organizational goals of DesignIT should be factored in the LAN design. I will also pay attention to network
throughput, line charges, security, and the integration of newer technologies in the future. When designing a LAN network, some issues must be
considered, one of these issues is the organization's short, medium, and long term goals. Several factors to be considered include the network
equipment, user applications, end–user equipment (workstations), and connectivity to the internet.
The LAN network for DesignIT will include other network devices which include gateways, routers, firewall, and cables. Without these devices
communication cannot be possible from a computer to another in the LAN network. Arouter and switch are the most important devices of a network.
Networks which are well configured and have a good infrastructure are helpful in improving manageability, performance, reliability and reducing
overall operating cost (Kenyon, 2002). To set up this LAN network for the DesignIT, the following are the hardware and software devices that I would
utilize so as to design the

performance? It does not seem irrelevant for us to know something that most of us deal in everyday life knowingly or unknowingly. The technology like

analyze the data on that image, we will see that the server located in the greatest distance is suppose to have higher latency but less download and
upload speed. But that's not what we see from the highlighted part of the image, right? Sever located in PA has 100 miles less distance than the server

Learning bridges also age address–table entries by deleting addresses that have been inactive for a specified amount of time.
The bridges within the network are transparent to users. Packets are sent through the bridge automatically. In fact, users have no idea that their packets
are traversing a link leading to a different location.
Bridges Versus Access Points
Access points connect multiple users wirelessly to each other and to a wired network. Several users equipped with 802.11 NICs might associate with a
single access point that connects to an Ethernet network. Each of these users has access to the Ethernet network and to each other. The access point in
this case is similar to a bridge device, but the access point interfaces a network to multiple users. A bridge interfaces only other networks.
It's possible to use a wireless bridge indoors. Awireless LAN bridge can interface an Ethernet network directly to a particular access point. This might
be necessary if few devices, possibly in a far–reaching part of the facility, are interconnected through Ethernet. A wireless LAN bridge plugs into this
Ethernet network and uses the 802.11 protocol to communicate with an access point that is within range. In this manner, a bridge enables the wireless
connection of a cluster of users (actually a network) to an access point.

An Ethernet–to–wireless bridge connects directly to a single computing device through an

Main Types Of A Network
Part One: Hubs: Hubs are used to construct a network by connecting multiple computers in a star / hierarchical network topology, the most
common form of local networks now every day. A hub is a simple device when it is sent bits of computer data from A to B, it is not to examine the
purpose, instead, it sends the signal to all other computer (B, C, D ..) within the network. B will then get it, while rejecting the other nodes. This
confirms that the traffic is released. Hubs works in the Physical layer in TCP/IP protocol stack. There are two main types of stroke: 1. Liability:
The signal is transmitted as it is (it does not need power). 2. Active: The signal is amplified, so they function as a repeater. In fact, they were called a
multiport repeater. (PSU) Hubs can be connected to expand the network to other platforms with an uplink port. Switches: Switches place the other
side are more advanced then hubs, Instead of diffusion through the frame, a controlled switch makes for the destination MAC address and forwards
the appropriate port only reach the computer. In this way, switches reduce traffic and divide the collision domain into segments, which is very suitable
for busy LANs and protects photos, from other computers sniffed the same segment. A table with the MAC address belongs to which segment is built.
If a destination MAC address is not in the table, it sends all segments except the source segment. If the same objective as the source of the frame is
rejected.

Application Layer 7 Of The Osi Model
RADIUS service: Description The RADIUS also known as Remote Authentication Dial–In Service, which takes place at the application layer also
known as layer 7 of the OSI model. It is a protocol that is used to communicate to and from the NAS (Network Access Server) and also to the AAA
server. RADIUS was developed as access server authentication and accounting protocol. It is used as both a client and server protocol that is also a
software that allows remote access to servers to allow servers to communicate with the main server, by doing this it allows the server to authenticate
dial–in users and allows authorised access to the services that was requested. RADIUS is an industry standard that is used by a various number of
network product companies, it is also a proposed IETF standard. The RADIUS is known to be considered as a connectionless service How RADIUS
works RADIUS server's support 's various types of authentication methods to allow a user to have authenticated access, by using the user's username
and password. Some of these authenticated methods are the Point–to–point protocol (PPP), Password Authentication Protocol (PAP) or Challenge
Handshake Authentication Protocol (CHAP) and there are other methods of authentication that could be used with RADIUS. When a user tries to log
in it sends a query – Access–Request from Network–attached Storage (NAS), the user will then be asked to submit their username and password, and
the radius will then sent the username and password

Wireshark Essay
First, let's talk about Wireshark, it is the most common network packet analyzer used worldwide, perhaps one of the best open source (free) packet
analyzers today. It lets you capture and interactively browse the traffic running on a computer network, helping you analyze and manage the traffic in
your network. Like a measuring device used to examine what is going on in your network cable, like a voltmeter used by an electrician to examine
what is going on inside an electric cable. Therefore, gives you the tools to do in depth network analysis, it will try to capture network packets and
display them as detailed as possible for analysis. Furthermore, used for troubleshooting network problems, examine security problems, debug protocol

Nevertheless, it gives the option to colorize packet display based on filters, create various statistics, rich VoIP analysis and much more.
The software does not provide intrusion detection system capabilities for your network. As a result, it will not warn you when someone is trying to do
anything bad to or on your network but it will help you to find out. Additionally, it will not manipulate things on the network, it will only display things
from it. Furthermore, it does not send packets on the network or does other active things.
System requirements for Windows operating systems. It will support any current version of Windows that is still in the extended supported lifetime and
any modern 64–bit AMD64/x86–64 or 32–bit x86 processor. Requires, 400 MB available RAM but larger captures require more RAM also 300 MB
available disk space but capture files require more space from your system. Additionally, it recommends 1280x1024 resolution or higher, at least 16–bit
color and a supported network card for capturing ethernet and/or 802.11 (wi–fi). Wireshark supports most Unix and Unix–like platforms and the system
requirements are the equivalents of Windows systems.
An alternative free network analyzer (Packet Sniffer) application available is Capsa it allows you to monitor network traffic, troubleshoot network

Essay On Ethernet
Ethernet, which has for quite a while been used for neighborhood (LANs), is dynamically being used for metropolitan region systems (MANs). Since
it is conspicuous, fundamental, and down to earth, it is getting the chance to be doubtlessly pervasive as a strategies for transporting data in a MAN. A
basic for giving different levels of administration in a MAN is the ability to help and keep up benefit level assentions (SLAs). Proper organization of
SLAs ensures that customers don't harm their understandings and makes it possible to guarantee nature of administration (QoS). Such organization

In a MAN application, quick Ethernet (that is, GbE and 10GbE) addresses optical fiber. Copper–based media just don't go up against the hailing paces
and detachment requirements, and remote courses of action are unreasonably compelled with respect to transmission limit and screw up execution.
While the bigger piece of optical frameworks at this moment used as a piece of assistance of quick Ethernet organizations are SONET–based, about
couple of make usage of FDDI. Creating options consolidate Resilient Packet Ring (RPR) and Generic Framing Procedure (GFP).
Metropolitan Area Network (MAN):–
A metropolitan area sort out (MAN) is a framework that interconnects customers with PC resources in a geographic region or locale greater than that
secured by even a broad neighborhood (LAN) however more diminutive than the district secured by a wide range orchestrate (WAN). The term is
associated with the interconnection of frameworks in a city into a lone greater framework (which may then moreover offer gainful relationship with a
wide region orchestrate). It is similarly used to mean the interconnection of a couple of neighborhood by traverse them with spine lines. The last utilize
is similarly every so often insinuated as a grounds organize.

The IEEE 802.11g standard
This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users.
Our Wi–Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi–Fi access points in our
network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones,
digital cameras, tablets and digital audio players connected using the Wi–Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors

Data security: Magnetic fields and current induction work in two ways, they just don't generate noise in signal carrying conductors; they also let the
information on the conductor to be leaked out. Since there are no radiated magnetic fields around optical fibers; electromagnetic fields are confined
within the fiber. This makes it impossible to tap the signal being transmitted over fiber cable. Thus the fiber cable is the most secure medium available
for carrying sensitive data. iii. Non Conductive: A serious concern with outdoor cables in certain computer networks is they can be hit by lightning,
causing destruction to wires and other cables that are involved in the network. Fiber optic cables can be made non–conductive by avoiding metal in
their design. These kinds of cables are economical and standard for many indoor applications. Outdoor versions are more expensive since they require
the special strength members, but they can still be valuable in eliminating ground loop and protecting electromagnetic equipment from surge damage.
iv. Eliminating Spark hazards: Fiber optic cables do not produce sparks since they do not carry current. Most electric potentials create small sparks
which can be extremely dangerous in areas like chemical plants or oil refinery where air is contaminated with potentially explosive

Advantages And Disadvantages Of Network Virtualization
.2 Network Virtualization
In computing, network virtualization is the process of combining hardware and software network resources and network functionality into a single,
software–based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource
virtualization.
Network virtualization is categorized as either external virtualization, combining many networks or parts of networks into a virtual unit, or internal
virtualization, providing network–like functionality to software containers on a single network server.
In software testing, software developers use network virtualization to test software under development in a simulation of the network environments in

Obviously, we may utilize PVST or MST to give an unpleasant sharing of burden by part the crossing tree inclinations for distinctive VLANs, however
the outline still doesn't change generally speaking. I've discussed this in East West and North South systems outlines. The fundamental point is that
there is a LOT of data transfer capacity that is never equally used – and that implies squandered power, space and cooling (which cost more than the
gear itself). When you move to a Layer 2 MultiPath system, the intention is to evacuate the unused switches in your system and expand the usage of
every one of your benefits. This can be most successfully done by disposing of the appropriation layer. Cisco FabricPath is a Cisco NX–OS
programming development joining the fitting and–play straightforwardness of Ethernet with the unwavering quality and adaptability of Layer 3
directing. Utilizing FabricPath, you can construct exceedingly adaptable Layer 2 multipath systems without the Spanning Tree Protocol. Such systems
are especially suitable for extensive virtualization organizations, private mists, and elite registering (HPC) situations. "Cisco turned on yet another new
component in the Nexus 7000 stage that essentially dispenses with the old and all around sent crossing tree convention from system outlines,

The Importance Of Uplink Over Utilization Protection
Uplink over utilization protection – It's important to establish thresholds when looking at both short and long term utilization and growth of the
network infrastructure. Doing so eliminates guesswork and provides a clear understanding of when additional resources should be required.
Specifically speaking, a threshold is normally based on percentage of usage (in comparison to the maximum available bandwidth). Example; 50% of
100 Mbps translate to 50 Mbps of overall usage. When establishing a percentage threshold, it's important to consider things like "margin of safety" and
"historic growth rates". In the case of "margin of safety", the threshold number should be high enough to alert that more bandwidth will be needed, but
low enough to... Show more content on Helpwriting.net ...
One other thing to note regarding bandwidth, the difference between 100 Mbps and 1 Gbps is capacity, not speed of operation. A 100 MbpsEthernet
connection is capable of passing 100 megabits of data in a one second period. In comparison a 1 Gbps is capable of passing 1 gigabit of data in a one
second period. The actual speed of the data is the same, it's just capable of passing more data in a one second period. (Think of 100 Mbps connection
as a single lane road with a 1 Gbps connection as a multi–lane highway with the speed limit of both roads being 55 Mph). In this example more cars
can travel on the highway as compared to the single lane road, but are still traveling at the same speed.

General bandwidth utilization guidelines
As a general rule of thumb, the chart below (see figure 1.1) shows a general guideline indicating the peak percentages of utilization on a LAN or
WAN, and what (if anything) needs to be addressed depending on peak utilization. With regards to peaks, another factor needs to be mentioned, and
that's the frequency of peaks. The frequency of peaks defines how often the peaks occur. This is an important point as the higher the frequency the

Company Overview Patton–Fuller Community Hospital is a community hospital that provides healthcare services designed to meet the needs of
patients at every stage of life. The hospital was originally founded in 1975. Patton–Fuller Community Hospital has been an important part of the
community since its opening. Patton–Fuller Community Hospital is located on the corner of 61st. Street and Jump Street (Patton–Fuller Community
Hospital, 2013). Patton–Fuller Community Hospital has provided quality healthcare services for the entire family since its opening while keeping its
patients information and data secure even in this current ... Show more content on Helpwriting.net ...
These two layers perform routing and deals with end to end issues. The hospital currently uses a CISCO ASA 5510–VPN router to connect to the
internet. Finally the session layer, presentation layer, and application work together to make the network operational. These three layers actually make
all the data be visible to the end users. These layers also make the data and network usable to the operator. Patton–Fuller utilizes Windows Explorer and
its company's webpage for these layers (Patton–Fuller, 2013).
Recommended Protocols For Patton–Fuller to fully utilize their potential networking power, the following protocols should be utilized. Patton–Fuller
should utilize a Gigabyte Ethernet Network for all its hardwired LAN connections. Gigabyte Ethernet is part of the family of Ethernet computer
networking and communication standards. The Gigabit Ethernet standard supports a theoretic data rate of 1 gigabit per second. Gigabyte Ethernet
networks are connected by CAT5e and CAT6 cabling (Gigabit Ethernet, 2013). The Gigabyte Ethernet network should be accomplished by using layer
3 switch. A layer 3 switch is a high–performance device for network routing. Layer 3 switches actually differ very little from routers. A Layer 3 switch
can support the same routing protocols as network routers do. Both inspect incoming packets and make dynamic routing decisions based on the source
and destination addresses inside. Layer 3 switches improve on the performance of routers

specifications allowing them to be connected with each other using a common connecion such as Ethernet or wireless. This establishment allows the
sharing of resources from the device through the network and to the desired destination such as another device e.g. Mobile phone, pc, tablet etc. all
locally within the network by Ethernet etc. In this scenario the LAN network is used for gaming where two computers connected to the same network
are trying to connect with each other to allow an established connection between the two allowing data to be shared, effectively creating a game server.
A user will mainly use a specific LAN to share data between clients by pairing them together.

A Brief Note On The Quality Of Service
Abstract: The Quality of service in general refers to capability to provide flawless, fast and consistent communication across the network. The factors
that influence QoS are error rates, bandwidth, throughput, transmission delay, availability, jitter, etc. Any network must provide secure and reliable
service and to achieve this it needs to consider the above factors. Hence we can say that the QoS of a network is a set of factors to efficiently use the
resources of the network. I am using the above factors to measure the QoS of different networks and compare them.
Introduction:
In recent times Quality of Service has emerged as one of the important topics for research. QoS can be defined as the all round performance of a
computer network. Any network is expected to provide secure and reliable service. QoS helps provide better service and this can be made possible
either by increasing the priority of a flow or by decreasing the priority of another flow and this flow can be managed by using congestion management
mechanisms. If a network capacity is insufficient then the QoS becomes an important factor, for example for real time streaming multimedia
applications like Skype, online games, youtube etc., as in such applications if the delay is too much then the purpose of the application will not be
served. The factors that influence Quality of Service are: Error rates Bandwidth Throughput Transmission Delay Availability Jitter

EVOLUTION OF IEEE 802.3 STANDARD [1]
In 1970s, Dr. Robert M. Metcalf developed a network, Alto Aloha Network that enabled the sharing of printers to personal workstations at data rate
3Mb/s. In 1980, DEC, Intel, and Xerox released the DIX Standard for Ethernet that made Ethernet open standard for network operations.
Further, Institute of Electrical and Electronic Engineers (IEEE) created a working group 802 which developed network technology standards numbered
as 802.x, such that x was the subcommittee number who developed it. So, in 1985, the subcommittee 802.3 developed Ethernet standards called
Carrier Sensing Multiple Access with Collision Detection (CSMA/CD).

remember that there is a 12–year statute of limitations on construction defects liability." Tuck notes that, when soliciting bids, you can specify that the
contractor will use a particular sub–contractor you trust. "For instance, our customers could say to a general contractor, I'd like a bid, and you have to
use Atlas Heating for the HVAC' [Heating, Ventilation, and Air Conditioning]," Tuck explains. "If you have someone you trust who does a particular
job, don't be afraid to require them as a sub–contractor when you seek bids." Lastly, Tuck says homeowners should not be afraid of using union

of a power outage. The data center also contains two printers, an IMAC computer and a Promise 48TB RAID disk storage.
STANDARDS
There are many LAN standards utilized by Patton Fuller Hospital all of which are baseband Ethernet LAN's. IEEE 802.3 is the working group that
creates and defines the entire family of Ethernet standards (Goleniewski, 2007). First, 802.3ab, which was completed in 1999, is 1000base–T Gigabit
Ethernet over twisted pair at 1Gbps. 802.3ab uses UTP category 5, 5e, 6, or 7 cables. Gigabit Ethernet is capable of transmitting 1Gbps of data over
distances of 300ft. It is easy to implement because most companies already use a category 5 or higher grade of cable. The second standard LAN
standard used in the hospital is 802.3x or 1000Base–X Gigabit Ethernet over fiber at 1 Gbps. Gigabit Ethernet builds on top of the Ethernet protocol but
