2 Key Considerations: When researching the new office location in Fayetteville, NC, I discovered that the two key considerations for designing the network are the communications media and the mode of data transportation. These two key considerations will guide the approach in a way that will help make the appropriate decisions based on the company’s needs. They will also help tailor the design around the employee’s needs to create a seamless interactive experience for the employees both working remote and on-site. The communication or data transmission mode refers to the transfer of information between two devices with the use of a communication channel such as: optical fiber, wireless channels (Wi-Fi), copper wires, and other forms of storage media (scaler topics, NA). There are three types of transmission modes, and each channel has a specific direction based on the transmission media. These three channels are: simplex, half duplex, and full duplex. Information within the simplex transmission mode flows in one direction. The configuration within the circuit is adjusted to either transmit or receive (scaler topics, NA). A half-duplex transmission mode is like a simplex except for the fact that a half-duplex’s directional flow of information can be reversed but, a simplex is fixed to go one way always. A good example of this would be a walkie-talkie. Only one person can talk at a time while the other person listens, and the other person can then switch to where they are now the one talking while the other is listening. A full duplex mode allows for information to flow in both ways simultaneously with the use of two simplex channels. One channel pushes the information in one direction while the other flows in the opposite direction. A good example of this is the IOS messaging app, iMessage. You can text and receive text messages simultaneously. I believe the full duplex mode of transmission should
3 be used in the new location because it would allow information between the corporate headquarters and the other offices to flow simultaneously both ways without delays occurring. Determining what common network hardware components will be needed for the for the new location is an important step in building the network. Firstly, I recommend a LAN network that has a switch managed by the IT department so they can monitor the traffic. Another important and common hardware component is a business modem with wireless access points connected to it that supports speeds up to 1GBPS since the building will offer fiber optics. The modem will be connected to the LAN which will then be connected to the company’s internal network and the internet through an internet service provider and will be setup as a wide area network connection to connect to the other locations. The internet service provider (ISP) will also provide the company with a public IP address to establish a connection to the internet. This will allow the employees to live video chat with employees based at the company’s other sites and reliably send print jobs to billboard printers to the company’s headquarters in Albany. I also recommend a physical firewall connected to the WAN for a standard layer of protection.The IP range considerations for a company with 150 employees at company headquarters, 50 employees in the Springfield, MA office with 50% of them being mobile and 50 employees being hired at the new location in Fayetteville, NC are important to ensure a high level of security and smooth functionality. I highly recommend using a private IP address with a decent range to allow the use of multiple single IP addresses within the company’s network. LAN topology The LAN topologies that can potentially be used at the new location to support the desired architecture are mesh topology, bus topology, star topology, and ring topology. A mesh topology connects each communication device on the network directly to each other. A bus or
