Network Design Proposal

NETWORK DESIGN PROPOSAL

ARTICLE IOVERVIEW

In May 2019, Johnnie came to us to design a network architecture for his small business and home networks. He explained that he had limited funding but wanted the most up-to-date network he could afford. He would need 3 computers; one for the front of the business to be used as the store’s main computer. A second computer would be placed at the back of the store and should be able to access everything from the front computer. A third computer will be inside Johnnies home, 200 ft away from the store in a separate building and it needs to be able to be on the same network as the store’s computers. He also explained that he is interested in network security because although his business does not save customers credit card information, they do store customers home addresses for a mailing list. The home was built in the 90s, and all wiring is up to code.

NETWORK ARCHITECTURE
LAN (local area network)
I believe a LAN (local area network) network would be most suitable for Johnnie’s situation. The local area network is a system that connects computers in a small area. Each computer is one connection (a node). Local area networks also allow peripheral devices such as a network printer, which each computer on the network can use.
P2P (peer-to-peer)
A P2P (peer to peer) connection would be preferred. Each computer will be connected via the internet. Files can be shared directly between each computer without having to physically transfer them. In other words, each machine on the P2P system turns into a file server. The only requirements are the internet connection and the P2P code.

TRANSMISSION
Wired/Wireless Combination
The store has the internet installed with a working modem. I have 2 options for transmission.
Option 1
A 2 ft trench would be dug between the store and the house. An estimated 250 ft of Cat6 cable would be ran between the buildings to cover the 200 ft distance between the two. At the store with the modem, a Cat6 cable would be connected to the LAN port of the wireless router. A Cat6 cable would be ran from the router to the front house computer, in case of router issues the computer would still be able to access the network. The computer at the back of the store can connect to network via Wi-Fi. The Cat6 cable that was ran from the store to the house would be connected to the LAN port of the house router. The computer in the house would connect to the network via Wi-Fi. The routers I have chosen should be able to reach the house computer from the store because of its extended antennas. However, if it does not, the house can rely on the wired transmission. This would make both the store and house Wi-Fi capable and in case of router issues, would keep the store running smoothly.
Option 2
This option uses powerline adapters to connect the store and house on the same network. The modem connects to a powerline adapter using an ethernet cable. The powerline adapter is plugged into a wall electrical outlet (in store). Once plugged in, you can use the powerline adapter to send and/or receive files and data over your home’s electrical to a second powerline adapter plugged in another location (the house). Connecting your networked-enabled streaming devices and router to powerline adapters is almost like connecting them directly to each other using ethernet cables. For this option to work, both store and house must share the same mains.
NETWORK HARDWARE
Specs
Routers: TP-Link AC1900 (2x)
This router is compatible with all Wi-Fi devices, 802.11ac and older. It is a gigabit router with 4 gigabit LAN ports, fast access to multiple connected wired devices. Long range coverage by 3 external antennas. Beamforming technology makes the router smart detecting where you need fast wi-fi. 1GHz powerful dual-core processor easily handles multiple devices. It is also very affordable.
NETWORK SECURITY
The appropriate small business network security system is critical for business owners. An Anti-Virus program that is installed on all 3 computers will help the network to be less vulnerable. The Anti-Virus I have chosen is Avast Internet Security. It includes Secure Line VPN service, a virtual “sandbox” for opening unknown files, a ransomware shield, firewall, and a sensitive data shredder. Keeping your software up-to-date is also important as it keeps all programs with the newest security patches. Business and home networks alike should always ensure their networks are protected by WPA2 encryption (passwords). Powerful passwords keep unauthorized people from hijacking your wireless network.
