words)
Good buy food services focusses in the supply of fast foods for a local community college
campus. Our services are available 24 seven for students who walk in and online services.
Our delivery systems are on time and guaranteed. Online Restaurant Ordering Services
will be conducted in the Good buy food services restaurants. The restaurant will be in one
building. It will comprise of local access network, LAN with 10 clients. CAT 5e shielded
twisted pair cable will be used in connecting the LAN. The LAN will have network hubs,
switches and wireless access points. The distribution layer will be the building backbone,
which will connect the LAN. Campus backbone is eliminated since there is only one

web server, which will be sufficient for the requirements of the restaurant. Internet Access
will be provided through
Internet Service Provider. There won’t be any need for WAN since the restaurant is located
on only one campus and therefore has no branch or office at any other location. A. Physical media selection: summary
CAT-5e shielded twisted pair cable will be used to connect the LAN due to the following
reasons – It is one of the best suited and most popular media used in LAN.
It is very cost effective.
The maximum transmission distance required for the restaurant is around 60 meters,
which is well within the optimal performance range of twisted pair cable (100 – 300
meters)
It provides better security compared to wireless media and is sufficient for the needs of the
restaurant. Fiber optics is being rejected on cost grounds.
It provides lower error rates than wireless media and it is sufficient for the needs of the 5 MIS 589 Applied Research Project restaurant. Fiber optics is being rejected on cost grounds.
It provides data transmission speeds of 10 – 100 Mbps, which are sufficient for the typical
network traffic of the LAN with 10 clients. A.1 Physical media consideration: Types of network and transmission distances
Twisted pair cable are most effective in LAN with a transmission distance of 100 – 300 meters.
In the case of the restaurant, the maximum transmission distance will be 60 meters as it will be
used in LAN located in the same floor in one building to connect 10 clients and hence it is the
most suitable media within an economical price range. A.2 Physical media consideration: cost
The cost of Belden 1583A CAT-5e Twisted Pair Cable is approximately $0.25 per foot.
Approximately 200 feet of twisted cable will be required to connect the LAN with 10 clients
using a multi-point circuit. The cost for connecting LAN using Belden 1583A CAT-5e Twisted
Pair Cable will be $50. B. Medium access
The best suited media access control for the restaurant would be contention where the clients
wait till the circuit is free and then transmit data. The reasons for preferring contention over
controlled media access is – The LAN has only 10 clients with network traffic that is typical and not high – the industry
norm is to use contention media access for LAN’s with up to 20 clients and use controlled
media access for bigger LAN’s (based on network traffic).
Using controlled media access for small LAN’s with low network traffic would result in
ineffective utilization of bandwidth, as clients would have to wait for their turn to transmit
data though the circuits would be free. Contention media access provides for better
bandwidth utilization in this case as the clients can transmit data as and when the circuits
are free. C. Network design

1 Web Server Proposed network architecture The network for the restaurant is designed considering the following – Restaurant is based in a single campus of one building
Access layer comprising LAN of 10 clients
Distribution layer connecting LAN through building backbone
Campus backbone is not required as the campus has only one building
Data center will have the web server which will also provide e-commerce edge
Internet access will be provided through Internet Service Provider
WAN is not required as the restaurant has only one campus D. Network layer
The LAN of 10 clients will be configured as one subnet. The building backbone is configured as
another subnet. The LAN of the building is connected to the building backbone network
through a router, which will have its own IP address and data link layer address. The building
backbone network connects to a gateway router for providing internet access. Each device in
the network will have an IP address to uniquely identify it in the network. DNS will be used to
search for IP addresses, which are not known. Communication within the clients in the LAN
(within the same subnet) are handled by the router connecting the LAN. Communication
outside the LAN i.e. on the internet is handled by the gateway router. Conclusion
Online restaurant ordering services seeks to meet all the needs and requirements for its
customers on campus by providing outstanding and quality products and services. The system
will be friendly and also easy to use. The service will be implemented on a single campus with
one building and a LAN of 10 clients connected to the building backbone through a router.
CAT-5e shielded twisted pair cable is used for cost effective guided connectivity that provides
sufficient transmission speed and security and is best suited for the proposed LAN connectivity
of 60 meters. Because of the small size of the LAN (10 clients) and typical network traffic,
7 MIS 589 Applied Research Project contention media access is preferred over controlled media access for better bandwidth
utilization. Since it is a single building, single campus architecture, campus backbone and
WAN are not needed. Data center and e-commerce edge are combined through a web server.
Gateway router connects to the internet through an ISP. MIS589 Project Milestone 3 Online restaurant ordering services

LAN and Backbone Network Prepared by : Mavis Gyaase Approved by: Professor Terrence YI Date: 01/29/2017 Summary of LAN or backbone network for the proposed network (max 200 words)
Online restaurant ordering project needs enterprise computing. For online restaurant project
network, there is a requirement which must allow members of the organization to share
information, printers and other peripherals. The computing requirement of the organizations
met by a single LAN and WAN. The design of an enterprise computing network select will be
simple, functional and secure. Star topology was selected for the office. The reasons being 8 MIS 589 Applied Research Project
Easier to manage; easier to locate a defective node or cable problem, well-suited for
transmitting signals over long distances on a LAN, handles high-volume network traffic,
enables reliable communication and any single cable connects only two devices. With the
star topology each network host is connected to another network host with point to point
connection with central hub station CA. A. LAN design summary
Traditional LANs link Personal Computers (PCs), file servers, printers, and other network
equipment using CAT-5e shielded twisted pair cable as the transmission medium Users communicate through the LAN, exchange electronic mail and access multi-user programs and
shared databases. To connect to the LAN, a user must plug a computer into the network wall or
floor LAN outlet. This physical connection creates an environment of more or less stationary
workstations. Moving from one location to another necessitates disconnecting from the LAN
and reconnecting at the new site. Expanding a LAN usually means additional cabling, which
can be time consuming and adds to the LAN’s overhead. Large complex LANs servicing many
users located in different rooms or on different floors of a building, are usually subdivided into
segments to facilitate management. The SML is currently configured with a wired LAN topology
but with Ethernet switch and hub. A.1 Wired or wireless LAN functions
The computer network is made up of a large number of small LAN's spread all over the
campus. Thus, the campus network uses a fiber optic-cable as a transmission medium
(backbone) that allows a higher bandwidth and lower delay to interconnect its main buildings
to each other (intranet) and to facilitate their communications with the outside world via
9 MIS 589 Applied Research Project
routers (internet). In addition, the campus network has installed Gigabit Ethernet network
technology. The fiber optic-cable is directly linked to core Gigabit Ethernet switches that are
usually located on the first deck of each main building (network center). The data transmission
speed of this switch is rated at 1Gbps, which utilizes the single mode fiber optics.
Furthermore, within each deck in a main building, the core Gigabit Ethernet switch is
connected to 3COM Ethernet switches (running at 155 Mbps) via multimode fiber optic cable.
Those switches are combined in two stacks. Each stack consists of four modules that manage
a total of 96 ports. This patch panel is connected to each wall plate via Cat 5 that
interconnects either individual workstations or hubs that form small LANs. Moreover, the
network uses many types of servers to support its educational and administrative functions.
For instance, e-mail servers are dedicated to controlling incoming and outgoing mail
messages while web-servers are employed to support the Internet and multipurpose servers
are used to support campus user accounts needs A.2 Wired or wireless LAN link and device requirements
The campus backbone requirements for the wireless LAN in is queit straightforward, as no
additional hubs or switches would be purchased for the wireless interfacing. The two Cisco
APs will be connected to the existing Ethernet hub and switch, which belong to the wired LAN
in the network. The only requirement is to register the port numbers of the hub and switch
intended for wireless connections with the network administrator so that the wireless LAN
could be legally established. A.3 Wired or wireless LAN bandwidth and performance requirements
Network Equipment
The network is already equipped with one 16-port Ethernet hub and one 16-port Ethernet
switch. There are adequate ports left for the proposed 2 access points. Some Ethernet cables
would be needed to connect the access points to the wired LAN and the ten laptops would
also require ten radio Network Interface Cards (NIC). The NIC should all come from the same
10 MIS 589 Applied Research Project
vendor.
Number of Access Points
The access point links the wireless users to the wired network of file servers and Internet
access. Given the coverage of an access point using 802.11b standard, two access points
(with radius of 300 feet) should be adequate to cover the 400 square feet laboratory area. The
two access points could also act as redundancy for one another whenever one is down. As
the wireless coverage area in network is relatively small, no RF site survey is required.
However, an accurate method to determine the number of required access points is to
perform an RF site survey. B. Backbone network (if applicable) Conclusion
Equipping the wireless LAN capability for the restaurant room well for its roles and functions
as an ordering facility for students on campus. The design was meant to be simple and able to
achieve its desired objectives.
Additionally, with so much development taking place with wireless LAN standards and
technology, it is also important to design the wireless LAN with scalability in mind. The two
Cisco Aironet 1200 series APs and the ten Orinoco 802.11a/b combo wireless cards were
selected because they could be upgraded easily in the future and are able to utilize 802.11a,
802.11b and even 802.11g concurrently. MIS589 Project Milestone 4 Online restaurant ordering services 11 MIS 589 Applied Research Project Network Requirements 3 Good Buy Food Services WAN and Internet Prepared by: Mavis Gyaase Approved by: Professor Terrence YI Date: 02/05/2017 Summary of WAN and Internet requirements for the proposed network
The online restaurant ordering services of Good Buy Food corporation residing in the single
building arranging LAN need to well-organized and connected with the world of internet with
different WAN options. Internet connection is very significant for the usage of the online
services. The existing LAN network of the services corporation resides in a single building with
a number of switches, hubs, copper cables or wires connecting a diverse number of
workstations (10 clients) must have an outside connection such that clients will be able to
communicate as well as connect with external business operations using the facility of internet.
We proposed the WAN connectivity of existing LAN network that is mandatory to link other
branch sites and customers situated on the topographically distributed areas. It is also needed
to connect with Internet Facility Supplier that offers internet connection amenities to the
restaurant’s online ordering requests from the clients residing in dispersed locations. There are
recommended options for the internet and WAN association that deals with the various sort of
network traffic using it. For offering WAN arrangement, ISP to the branch office and head
office is necessary provided by different vendors arranging internet connection in the WAN
network. Hence, WAN and the Internet both equally are mandatory to fulfill the requirements of
the online restaurant services offered by Good Buy Food Services Corporation to the domain
clients outside their building respectively. 12 MIS 589 Applied Research Project A.1 Need for WAN connectivity
WAN associativity or linking is important for the restaurant services firm as to connect clients
worldwide. A WAN network arrangement aims to convey between at least two networks or
LANs. Good Buy Food Services is not a major association. So because of this reason Good
Buy Food Services do not have to fabricate their own particular WAN. Consequently, Good Buy
Food Services needs WAN specialist organization or merchant. As a result of WAN, Good Buy
Food Services LANs can convey. So WAN helps all LANs of Good Buy Food Services
warehouses can impart and impart their same database to moderate movement and security.
So for Good Buy Food Services, we are utilizing VPN programming. The VPN administration
was initially intended for minimal effort association among different geological locales. A.2 Traffic through the WAN
We are utilizing VPN for Good Buy Food Services network. A virtual remote network (VPN)
gives what might as well be called a private bundle exchanged system over public domain
Internet. It includes building up a sequence of PVCs that keep running over the Internet so
that the system demonstrations like an arrangement of committed circuits despite the fact that
the information streams over the Internet. Activity over VPN is little because VPN gives
allocated system to them. The likelihood of information exchange rate or usage to the
database will be less. Due to the committed system, movement makes because of Good Buy
Food Services Corporation will be less. They need to get to their system or utilize VPN when
clients were coming, and they need to request food items for various branch locations of Good
Buy Food Services Corporation. A.3 Possible WAN options
Good Buy Food Services is not a large scale food services association. Other WAN choices
accessible for Good Buy Food Services incorporate one that is committed circuit systems
where a rented line is characterized as an organization that is introduced and provisioned for
the selective utilization of the client. Devoted circuits charged at a level expense for each
month and the client has boundless utilization of the circuit. When you sign an agreement,
rolling out improvements can be costly because it implies re-wiring the structures and marking
another deal with the bearer. Devoted circuit systems are an expensive and old outline of
WAN, so it’s not a convenient choice for Good Buy Food Services. Outline hand-off is a
standout amongst the most generally utilized WAN administrations in the nation like the United
States. Like wired enabled Ethernet LANs network, it is a temperamental bundle arrangement
facility since it doesn't accomplish the fault control. Be that as it may, Good Buy Food
Restaurant needs dependable parcel approach, so it is not a decent choice. A.4 Explain your choice for WAN service
For Good Buy Food Restaurant, we are utilizing VPN. Since it, mechanisms in a similar
13 MIS 589 Applied Research Project manner as of private bundle exchanged system over global Internet. Good Buy Food
Restaurant need to pay the necessary network bearer for the circuit in addition to the ISP for
Internet usage. With the goal that they can associate a VPN portal (an exceptionally planned
switch or router) to every Internet get to the circuit to give admittance from your systems to the
VPN. The VPN portals empower you to make PVCs through the Internet that is termed as
network system tunnels. The VPN gateway device at the sender device partakes the active
bundle and epitomizes it with a convention that is utilized to drive it through the passage to the
VPN door on the opposite side. The VPN door at the collector takes off the VPN bundle and
conveys the parcel to the goal arrange. The VPN is straightforward to the clients; it seems like
a conventional package exchanged system PVC is being used. The VPN is likewise
straightforward to the ISP and the Internet in general; there is essentially a flood of Internet
bundles moving over the Internet. VPN programming package approach is regularly utilized on
home PCs or portable PCs to give the same secure passages to individuals employing or
operating from off-site. The essential focal points of VPNs are ease and adaptability. Since they
utilize the Internet to convey messages, the real cost is Internet admittance, which is
reasonable contrasted and the cost of committed circuit administrations and bundle-switched
administrations from a standard bearer. In like manner, anyplace you can build up Internet
facility, you can rapidly place in a VPN system. B.1 Role of the Internet in your network
The Internet offers a worthy role in our online restaurant commerce as it helps our clients to
connect with us at any instant of time they need to access and usage our online services.
Internet service is mandatory and required. Expending internet facility in our proposed network,
support computer clients to interact globally with the administration offering the web services
like e-commerce and food ordering services. Today, the Internet medium is the absolute most
utilized system on the planet. Its energy is tackled and utilized by numerous associations to
direct business. In its least complicated shape, it is a gathering of systems worked at different
levels by state, neighborhood, and government offices, and also not-for-profit and revenue
driven associations. To work VPN programming package, it requires the web. It will associate
that framework to the WAN through the network. A virtually isolated system (VPN) gives what
might as well be called a private parcel exchanged system over the general population
Internet. Good Buy restaurant...
