CMIT 495 WIRELESS DESIGN

Network LAN Design with VoIP and Wireless Services

This section will provide a detailed LAN-design of network with VoIP services, Wireless services, protocols, devices, and interconnectivity, with WAN.

This section includes but not limited to

Equipment List
Hierarchical IP scheme and VLAN
Link IP addresses
High Level Diagram
Voice and Wireless Design

Equipment List:

Select all networking hardware

Suggested Template

Device	Cisco Model#	Quantity	Comments
Distribution Switches	Cat 3850 Series Swiches		48 port model, wireless capacity/PoE
Branch office router	RV220W Wireless		4 port switch, built in firewall
Access Switches	Cat 2600	10	48 ports
IDS
Network Monitoring System
Fire wall
Cisco Unified Call Manger			Voice services

Step 2:

Now name each device as per naming convention (Since it is new company, make it for them)

Suggested template

Device	Device Configured Name	Placement	Connection	Comments
Cat 3850 Series switch	Data center Switch 1	Data center	Distribution Switch VLAN1, 2, 8	The switch has Inventory server, Payroll server, and VLAN 1, 2, 8
Core Switch 7600 Series	CoreRouter1	Room#1014	DSW1 and DSW2	ISP1

Hierarchical IP scheme and VLAN

Create an IP Scheme and VLANS.

I suggest use the table below to create your hierarchical IP addressing scheme.

Location	Number of IP Addresses Required	Future Growth	Rounded Power of 2	Number of Host Bits	Subnet Address Assigned
Floor1	1500	200	2048	11	172.20.0.0-172.20.7.254/21
Floor2	200	100	500		172.20.8.0-172.20.9.254/23
Floor 3	45	20	128		172.20.16.0-172.20.16.122/25
Floor4

Create VLAN: In creating VLAN, I will suggest use organizational structure model for simplicity.

Examples: VPOPRVLAN1, VPOPRVLAN2

High Level Diagram:

Drawing a network topology diagram is the most challenging task. To overcome this challenge, we need to use Cisco modular technology in upgrading the network in other words top down design approach. The top design approach starts with Application, Devices and infrastructure. You will also use the same approach in designing WWTC network. Select all the applications for the network. Then select the devices needed to run these applications. Now you are ready creating network topology diagram. Since, in WWTC network we have one floor, so all of our devices, application and infrastructure will reside in one floor.

Create subnets. Generally subnet matches organizational structure. Also, in a large network to increase performance or for security reasons, subnets are created. Furthermore to accommodate the need of a department, the subnets can be subnetted further or VLANs are created or both. Every organization have subnets and VLANs. Let us say we need 20 VLANs, which will serve client’s requirements, performance and security of the network. Assign these VLANs to switches. For example; you need 3 switches to host 3 VLANs for VPOPR. The diagram below depict the scenario.
