6. Subnetting and IP Addressing
In order for all three locations to be able to communicate and still be secure we
need to implement IP addresses and subnets. The IP addresses will provide connectivity
and communication and the subnets will provide security. This way we can make sure
that the separate divisions cannot access any other division’s information. An example
being the marketing division is not allowed access to see the sales division files and
documents.
The following is a chart breaking down the IP addresses and subnets:
Subnet ID Host Addresses Subnet Broadcast
192.168.10.0 192.168.10.1 – 192.168.10.62 192.168.10.63
192.168.10.64 192.168.10.65 – 192.168.10.126 192.168.10.127
192.168.10.128 192.168.10.129 – 192.168.10.191
192.168.10.190
192.168.10.192 192.168.10.193 – 192.168.10.255
192.168.10.254
The subnet ID is the individual IP address for each site. The host addresses are
the range of addresses available for client computers to access the network. The subnet
broadcasts are reserved for the connection out of the WAN to the ISP. The 192.168.10.0
address is going to be the address for Boston, MA. Next will be the backup in Miami, FL
with 192.168.10.64. The last network, 192.168.10.128, will be for San Francisco, CA.
As you can see in the chart we have extra hosts in each range and an extra network. We
have included this information to provide for company growth at each location and in the
event that a fourth location is necessary. Each host range accounts for 62 clients.

7. For this network structure the subnet mask will be 255.255.255.192 (/26). In total
there will only be two subnet bits and six host bits being used. This can be represented
by: 110nnnnn.nnnnnnnn.nnnnnnnn.sshhhhhh. The 110 and the ns represent all the
network bits. Because this is a Class C subnet we are working within the last octet of
bits. We can see that the first two are subnet bits and the remaining six are host bits.
All of this information is derived from VLSM. VLSM stands for variable length
subnet mask. Basically VLSM is a tool used to customize your network needs in regards
to IP addressing and subnetting. Therefore, you can subnet a subnet. VLSM along with
OSPF, Dual IS-IS, BGP, and EIGRP are routing protocols supported by Cisco. VLSM
requires a classless routing protocol.

13. Virtualization:
Using VM Ware
Virtualization is the process of partitioning (separating) servers so that they act as
multiple servers. This allows for the expansion of IT resources without incurring the
costs of physically expanding infrastructure. The main benefit of virtualization is that
it can cut a business' IT costs.
For example, a business with multiple servers could use server virtualization to
eliminate x number of those physical servers, freeing up space and cutting down on
the energy, maintenance and security costs related to their physical IT plant. This
method will primarily be used with the Backup Server at the Miami location, will be
highly considered for the all the main file server functions as well (DNS, DHCP,
Exchange, print, DBA, etc).
VM Ware is one of the leading vendors in the virtualization market, has been
around for over ten years. (In January 2008, 63 percent of organizations with over
500 employees and 40 percent of medium-sized organizations (100 - 499 employees)
were using server virtualization (up from 48 and 22 per cent, respectively, in early
2007). Adding to the fact that VM Ware is opensource (free), this will significantly
reduce the overall cost without the need of additional physical hardware.

14. Network Devices
Cisco 2800 Series Router
The Cisco® 2800 Series of integrated services routers intelligently embed data,
security, voice, and wireless services into a single, resilient system for fast, scalable
delivery of
mission-critical
business
applications. The
unique integrated
systems
architecture of the
Cisco 2800 Series delivers maximum business agility and investment protection. Three
routers will be acquired; one per site, and will be preconfigured before rolled into
production.
The Cisco 2800 Series features the ability to deliver multiple high-quality
simultaneous services at wire speed up to multiple T1/E1/xDSL connections. The routers
offer embedded encryption acceleration and on the motherboard voice digital-signal-
processor (DSP) slots; intrusion prevention system (IPS) and firewall functions; optional
integrated call processing and voice mail support; high-density interfaces for a wide
range of wired and wireless connectivity requirements; and sufficient performance and
slot density for future network expansion requirements and advanced applications.

15. Cisco Catalyst 6500 Series Switch
The new 3-slot Cisco Catalyst 6503-E Switch chassis offers a compact 4 rack-unit height
that is ideally suited for multi-Gbps secure data
centers, remote access, e-commerce, and converged
network solutions. The Cisco Catalyst 6503-E
provides maximum uptime with redundancy and
rapid (1 to 3 seconds) stateful failover across
supervisor engines. It provides support for modular Cisco IOS Software to minimize
unplanned downtime through self-healing processes and simplifies software changes
through subsystem in-service software upgrades.
The Cisco Catalyst 6503-E Firewall Security System is a 3-slot model providing an easily
deployed solution that integrates a Cisco Catalyst 6500 Series Supervisor Engine 720
(with integrated policy and multilayer switch feature cards [PFC3/MSFC3] for system
control, routing services, and dual-Gigabit-Ethernet ports); a Cisco Catalyst 6500 Series
Firewall Services Module providing 5 Gbps of firewall services; and a single open slot
for site customization. This will substitute for the need of configuring VLAN as well as
Firewall security.

16. Cisco ME 3400 Series Switch
The Cisco ME 3400 Series is the first Cisco access switch family optimized for both
Ethernet-to-the-Home (ETTH) triple-play services and Ethernet-to-the-Business (ETTB)
VPN services. It provides a complete security solution for Metro Ethernet access that
includes subscriber, switch, and network protection. The Cisco ME 3400 Series supports
multiple software
images to provide a
"pay-as-you-grow"
deployment model.
With service breadth
spanning triple-play and
Layer 2 and Layer 3 VPN services, lower total cost of ownership (TCO) and operating
expenses can be achieved from a single ETTH and ETTB access solution. Carrier
Ethernet is a huge growth area for emerging connectivity services. It is a comparatively
simple, cost-effective, and familiar technology whose migration to the WAN will lead to
more flexible network connectivity while reducing overall IT costs. To establish better
global standards that provide assurance that equipment from different vendors will
interoperate, service providers asked the Metro Ethernet Forum (MEF) to initiate a set of
standards and a certification program. The Cisco ME 3400 Series is certified to MEF 9
and 14 to support industry-standard Layer 2 services and QoS features.

18. VoIP Capability/Devices/Software
VoIP(Voice over Internet Protocol) is a protocol that allows telephone calls to be
made over computer networks like the Internet (example: Skype). VoIP converts analog
voice signals into digital data packets in real-time; allowing for two-way transmission of
conversations using Internet Protocol (IP).
VoIP calls can be made on the Internet using a VoIP service provider and
standard computer audio systems. However, some service providers support VoIP
through ordinary telephones that use special adapters to connect to a personal desktop
computer network.
VoIP offers a substantial cost savings over traditional long distance telephone
calls. The main disadvantage of VoIP is, like cell phones, a greater potential for dropped
calls and generally lesser voice quality. However, many ISP (Comcast) utilizing great
bandwidth for business can improve quality, albeit at a high premium.
The VoIP phone to be selected as a viable option is Cisco Unified IP Phone
7960G is designed to meet the
communication needs of
professional workers in enclosed
office environments--employees
who experience a high amount of
phone traffic in the course of a
business day. The internal Cisco
two-port Ethernet switch allows for

19. a direct connection to a 10/100BASE-T Ethernet network via an RJ-45 interface with
single LAN connectivity for both the phone and a co-located PC.
A large pixel-based display provides supplemental information, access to
applications, and makes it easy to use telephone features. It allows users to quickly access
diverse information such as weather, stocks, quote of the day, or any Web-based
information using extensible markup language (XML) to provide a portal to an ever-
growing world of features and information.
Another possible option for VoIP use, is the 3CX VoIP Phone for Windows. 3CX
VOIP Phone (Software) is
completely FREE, Which
allows the client end-user to
use a PC or laptop as a
phone. Connect 3CX VoIP
phone to a VOIP provider or
to an IP PBX to make calls to
any soft phone, mobile or
landline number.
