Executive Summary
Group A Technologies, Inc. is an industry leader in technology solutions for
any size business. The network solution proposed in this document will
help to move Continuous Corporation into the next generation of
technology excellence. Our comprehensive solution addresses the
pressing needs of Continuous Corp., linking your supply chain with your
marketing and customer service, logistics, finance, and senior
management. You will have a strong overview of the daily operations of
your company through the distributed network technologies we will
provide. Your manufacturing and distribution centers will be able to keep
in close contact with your sales and marketing, notifying them
immediately of inventory availability. Finance and Accounting will have
up-to-the-minute information on the financial health of your division.
Logistics will have updates on the availability of trucking resources for
fulfilling customer orders. With all this information at your fingertips, you
will be better equipped to make the crucial business decisions you make
every day.
Solution Overview
At each of your geographically dispersed
locations through the U.S., Canada, and Mexico,
we will need to install a Local Area Network (LAN)
to facilitate the sharing of information at that
location. Then, to link all of these locations to the
central division headquarters (which will have its
own LAN), we will use Virtual Private Networking
(VPN) technology for a secure connection and a
method of sharing information across the
internet. Each of these solutions is described in
detail below.
Advantages of using LAN Technology
The advantages of independent LANs are:
• Files can be stored on a central computer (the file server) allowing
data to be shared throughout the organization.
• Files can be backed up more easily when they are all on a central
fileserver rather than when they are scattered across a number of
independent workstations.
• Networks also allow security to be established, ensuring that the
network users may only have access to certain files and
applications.
• Software and resources can be centrally managed.
• Network versions of software often allow for their speedy
installation on workstations from the file server.
• Expensive devices such as laser printers or scanners can be shared.
• Users can access their files from any workstation(Comer, 2009)
Topology Set-up
• we are recommending a hybrid topology – a
physical Star topology, with a logical Bus topology
• each computer will be physically connected to a
central router that passes the information along
the network
• this network will really work like a Bus network,
because the router the computers connect to
would simply be forwarding information to the
destination, much like a shared wire in a Bus
network.
IP Address Assignment
To allow for future growth we will deploy a
technique called Classless addressing within
the class C IP addressing scheme.
• Will allow company to expand 1024 hosts on
the network. This should handle the growth
of company for the next 10 years or more.
Connection between sites
• In order to facilitate a connection between your various
sites, several technologies will need to be used. First, we
will want to use Voice over Internet Protocol (VoIP) for your
telephone system, as this is the most commonly used in the
industry today. Second, we will need to connect your
various LANs using a Virtual Private Network (VPN), which
will allow your company to connect through the Internet
with the various sites.
• Used for economic purpose of routers being cheaper than
switches and because sending both data and voice in IP
datagrams lowers cost because the underlying network
infrastructure is shared- a single set of equipment, wiring,
and network connections suffices for all communication
including telephone calls.(Comer,2009)
Network Connectivity
• All of the computer equipment needed by the end
users can be wired with a common, cheap, and easy to
use twisted pair (CAT5 or CAT6). For any equipment
that needs a connection to the network that is unable
to be physically connected by a cable, there could be
an internal wireless network. The connection to the
internet and networks beyond the company’s network
could be accomplished with the speed and capacity of
a fiber optic connection provided by an outside vendor.
• We believe that using a wireless local network at each
location, as well as a VPN connection between
locations will allow for the greatest flexibility and
opportunity for growth.
Wireless LAN Implementation Benefits
• Reduced Cost-of-Ownership: The initial equipment investment
required for wireless LAN can be higher than the equipment cost of
wired LAN. Life-cycle costs can be significantly lower, and long term
cost benefits are greatest in dynamic environments requiring
frequent moves and changes.
• Network managers in dynamic environments minimize the
overhead caused by moves, extensions to networks, and other
changes with wireless LANs.
• Network managers installing networked computers in older
buildings find that wireless LANs are a cost-effective network
infrastructure solution.
• Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks. (Comer,
2009)
Components Needed
• IP telephone - offers traditional telephone interface that allows a user to
place or receive calls.
• Media Gateway controller- provides control and coordination between a
pair of IP telephones allowing a caller to locate callee or access services
such as call forwarding, call waiting, voice mail, conference calls, caller ID.
• Media gateway- provides translation of audio as a call passes across the
boundary between an IP network and the PSTN or the boundary between
two IP networks that use different encodings.
• Signaling gateway- spans the boundary between a pair of disparate
networks, and provides translation of signaling operations, allowing either
side to initiate a call.
• This could be very useful for business network setup especially since there
are both people in the central offices as well as people on the go needing
access wirelessly. This would allow for video conferencing and other
communications across long distances to keep everyone on the same page
and the business at top performance. (Comer, 2009)
Security
• Security is not an expense, instead it is an
investment.
• Firewalls control the network packets that
pass between two networks or a network and
a node, and can keep unwanted external data
out and sensitive internal data in.
• A firewall acts as a protective barrier because
it is the single point through which both
incoming and outgoing communications pass.
