Network Infrastructure Selection for a Client

The assignment content compares the features and performance of various routers, switches, and wireless access points. The weighted decision matrix is used to evaluate each device based on its security features, speed, USB ports, and cost. The results show that Cisco RV220W Wireless Security Router/Firewall has the highest score (11 points) among the routers, while Cisco SG200-26 Gigabit Ethernet switch and Netgear ProSafe GS724T switch are top contenders among the switches with 12 and 13 points respectively. For wireless access points, Netgear WAC720 Access Point has the highest score (4 points). The total budget required for the client's needs is calculated to be $5,634.

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
