Network Planning and Configuration: Subnetting, LAN and WAN Design

This report provides a detailed network plan and configuration for a multi-site organization, focusing on subnetting for LAN and WAN environments. It includes an executive summary outlining the network requirements, such as the number of devices, servers, and WLAN access points across different locations. The report meticulously details the IP addressing scheme, subnet masks, and host address ranges for each subnet. It also presents router interface configurations, server details, and a comparison of various network devices, including routers, Ethernet switches, and wireless access points. Weighted matrices are used to evaluate the devices based on factors such as security features, speed, port numbers, and cost, leading to recommendations for the most suitable equipment, such as the Cisco RV220W router, Cisco SG200-26 switches, and Netgear WAC720 access points. Finally, the report provides a total budget estimate for the proposed network infrastructure.

Executive Summary
Network planning and configuration is a repetition procedure, which incorporates topological outline,
network-receipt and network- synthesis, and its objective is to guarantee that new telecom service or
network addresses the issues of the client and administrator. The procedure can be made as per each
new network or administration. Every one of these layers incorporates plans for various time
horizons, i.e. the business planning layer decides the plan that the operator should make to guarantee
that the network will play out the important time for its desired lifetime. Tasks and maintenance
layers, in any case, keeps an eye on how networks will keep running on a step by step premise.
The network plan incorporates 6 switches at every area in devices, 6 switches in every area, 3 WLAN
point access in Sydney Melbourne and Brisbane. Anyway, the quantity of switches for every LAN
relies upon the port number of the switch and the PC number of every LAN, 2 servers in Sydney
(Web and DB server) and 3 go down servers in Hobart. Among these devices, the most important
device is the server, the web server will handle the client requests while the database server will store
all the information. Periodic backup server will ensure continuous operation in case of any
phenomenon. Another important thing is that data analysis requires relatively good computers,
especially in CPU and memory. At a minimum, the cost should be as low as possible.

From the above table, Netgear WAC720 Access Point have the highest point. When
compared to other devices this is little bit costlier but the operating efficiency and performance is
good overall. Hence we can uses this device for the client’s need.

Total budget:
(6) Cisco RV220W Wireless Router = 6 x $363 = $ 2,178
(9) Cisco SG200-26 ports Switches = 9 x $304 = $ 2,736
(3) Netgear WAC720 Access Points = 3 x $240 = $ 720
Total = $ 2178 + $ 2736 + $ 720 = $ 5,634
