Existing LAN

Assessor of the WAN specification is discussed with the help of a design of WAN and the discussion containing the essential factors of the WAN. In this Assignment, all the required components of WAN are mentioned and discussed with their functions (Liu et al. 2021). The cost structure of the required components is also given, which will help determine the WAN's cost efficiency.

Required LAN, WLAN, and VPN segments

The required devices are mentioned in the given table. There is the function mentioned and discussed of the required devices and components. In the design of WAN, there are some specific devices that are mentioned (Wan et al. 2020). The levels or the segment of the devices are also given in the table and discussed.

Device/software	Resource Type	Segment/Level	Functions
Router	Routing Device	Level 0	To provide the connection between two Networks i.e. private and public networks. It forwards the packets based on the routing table database.
Switch	Switching Device	Level 0	This device helps to connect devices (computers, wireless access) with each other in a platform of a network.
Access point(AP)	Wireless Networking Device	VLAN 30	This device helps by creating a WLAN in organizations.
Computer	End Device	VLAN 300	This is basically a set of interconnected devices. It will help the users to input, the output data, and the user also can process the data, store the data, and also pieces of information.
Printer	Printing Device	VLAN 300	This device allows transferring the accepted information into a piece of paper.
Smart Phone	Phone system	VLAN 30	This device helps users and provides the facility of making and receiving any phone calls.
Firewall	Security Device	Level 0	This is a Security device of a network that will help by filtering the incoming and outgoing traffic depending on the security policies.
Home Router	Wireless Routing Device	VLAN 3	This device provides the connection between networks or subnetworks and gives access to other wireless devices.

Physical Environment and WAN

The design of the WAN is created and depicted in the above figures. The requirement of the devices is mentioned in the design of WAN. This design of the WAN includes some devices and components (Kim et al. 2018). This component has its own facility and ability to work. Depending on the physical environment of the company there can be some unwanted regulations in the environment that can harm the components. The components are working according to the weather.

According to the location, this WAN design is going to implement in Brisbane. So,
Organization is located in the city: Brisbane
Organization is located in a regional town: South East Queensland
Organization is located in an isolated area: NA

Bandwidth Required

The design of the WAN requires bandwidth according to the requirement of the users. The requirement of the users are given below,

Skype for upload and download speed for one user: 1.2 Mbps / 1.2 Mbps
Office 365 average bandwidth requirement per user: 26 / 26 kbps
VPN bandwidth required to share video, image, and text files: 10 Mbps/ 10 Mbps
Total bandwidth required for one user: 11.2 Mbps / 11.2 Mbps
Total bandwidth required for 75 users: 840 Mbps / 840 Mbps

WAN Components

Device/Software	Resource Type	Segment/Level	Functions
Router	Routing Device	Level 0	To provide the connection between two Networks i.e. private and public networks. It forwards the packets based on the routing table database.
Modem	Networking Device	VLAN 30	This device will help to provide the facility of transmitting data with the help of modulating.
Firewall	Security Device	Level 0	This is a Security device of a network that will help by filtering the incoming and outgoing traffic depending on the security policies.
VPN Gateway	Wireless connection	VLAN 30	This provides the facility of a network that is virtually private.

Vendor Option and Costs

In this part of the assignment there are some components needed. The costs of the required components are given below,

Product	Description	Quality	Unit price (ex. GST)	Segment
Router	Routing device	1	865	Level 0
switch	Switching device	3	1500	Level 0
Firewall	Security device	1	1000	Level 0

WAN Design

This above-given figure depicts the design of WAN for the company (Lee et al. 2020). The components are required by the company. In the design, all the components can be depicted easily.

2901 Router-01 is the router needed in the design by the company.

2980-24TT switch01, 2980-24TT level01-switch02, and 2980-24TT level01-switch03 are the switches that are required by the company.

Access point 0 is the needed AP required by the company.
5508-X Firewall-01 is the firewall required by the company.
Smartphone0 and smartphone2 are the phones that are required by the company.
PC0 and PC1 are the computers needed by the company.
Printer0 is the printer that is needed by the company.

Design for Redundant Links

This above-given design is the design of WAN that is designed for the company with the required device and components that is required by the company.

IP Addressing Scheme

This above-given figure depicts the configuration of the IP address in the required router of the WAN design (Radosavovic et al. 2020). Here the IP address is 192.168.0.1 and the subset IP is 255.255.255.0 for the required router.

This above-given figure depicts the configuration of the IP address in the required firewall of the WAN design (Gao et al. 2020). Here the IP address is 192.168.1.5 and the subset IP is 255.255.255.0 for the required Firewall. The firewall is connected to the internet for that reason the firewall configuration is done with the internet.
