7-1 Final Project Joshua Rose IT-212: Intro to Computer Networks Prof. Livingston October 12, 2023

Key Considerations for Fayetteville, NC 1. A reliable ISP: Making sure a solid steady high-speed connection is extremely important for effective coordination between employees and sharing of media 2. Support for teleconferencing: Having a strong network to support video conferencing between locations, in order to have proper communication all at once for employees across locations. 3. Printing transmission: The ability to be able to directly send projects to print for prototyping or confirmation is vital to the business when all locations are connected across the country. Constraints 1. Budget limitations: In order to try and maintain a fair budget. With opening a brand-new location, there are typically some forms of financial caps with what hardware is able to be ordered. 2. ISP decision: The building being wired for many versions of connections would typically come with a choice of providers for the style and speed of a connection your business requires. Considering speed, security and reliability are going to be crucial in determining the service we use. A higher speed will increase productivity while needing to send large files quickly between one another in order to get projects done at a faster rate. I will include the following information of a system utilizing the Open Systems Interconnection (OSI) model. This model is made up of seven layers that allow computer networks to have diverse communication over the network as a whole. Lan Topology

 Application - Human-computer interaction layer where applications can access the network services. Its responsibilities are for the protocols and data manipulation that software will rely on to present data to each end user, also known as the human-computer interaction layer.  Presentation Layer - Translates or formats data for the application layer  Session Layer - coordinates and terminates conversations between applications.  Transport Layer – Responsible for transferring data across a network and provides error-checking mechanisms and data flow controls.  Network Layer – This primary function is to move data into other networks.  Data Link – Aka Protocol Layer, this manages the moving of data into and out of the physical link in the network.  Physical Layer – Transports data using electrical, mechanical, or procedural interfaces. Network Hardware Components : Key network hardware components, including routers to maintain a secure distribution of the network while also allowing a defined and secured wireless range to employees within the office, switches so we can accurately supply the entire office with the required network connections, firewalls in order to maintain and create security within the network, and access points, are essential for network connectivity, security, and wireless access. IP Range Considerations : IP addressing will need to be designed to accommodate the eventual size of the network and potential growth outcomes. Correct subnetting and addressing scheme designs will be necessary to effectively allocate IP ranges across multiple departments and other in-house devices. I would consider using the 10.x.x.x IP range, being that it has a wider range which would end up being less suspect to network complications and scaling would be easier.

Considering and IP range of 196.168.x.x would not work as well, being that it is a more common, less secure range. It is also mostly used in a setting with fewer than 200 users. LAN Topology : Considering the requirements and goals of the company, the recommended LAN topology for the office would be a star topology. LAN topology will allow for simple management and easy expansion when the company continues to grow. The central switch is able to connect all devices and if a switch were to fail, it would not have any effects on the network as a whole. The star topology can support teleconferencing and the ability to send print jobs across the network. Bringing in a star topology will enable the NC office to have an efficient network infrastructure that will meet the needs, goals, and objectives of the company. Installation of redundant links and redundant switches will enhance network quality and decrease fault occasions. Internet Service Provider. Of the many options available for internet service in that area, I would consider using either Spectrum or MetroNet. They allow for much higher upload and download speeds compared to some of the other providers. Spectrum is a very reliable service provider with decent speeds up to 1,000 Mbps and has proper support for business clients. I would more than likely go with MetroNet though, with speeds up to 10Gbps, this would easily allow for seamless upload and downloads for file sharing and mostly uninterrupted video conferencing when needed. Hardware, Software, Printers and Bandwidth

As for the hardware and software to consider for the new office. We should consider the following items. Routers & Switches : To create points for the connection to be shared amongst the users in the location, create and manage secure VPN tunnels from this location to other company locations. Modems : The provided high-speed modem provided by MetroNet would be adequate for the needs of the office. Computers : I would suggest using Dell’s business branded systems, as they provide strong and lasting hardware solutions, great speeds and reliability. They can be customized per system if we require special setups for individuals in the office. They also have great business bulk buy pricing. Software: I would suggest going with one of the better all in one business software solutions, being Office 365, offering the whole suite of programs offered, installed locally and cloud application support. The subscription also allows for 1TB of storage and more upon requirements. Printer Configuration: As for the printer options in this new location, I would go for something feature packed but not an industrial size. The Brother MFC-L8905CDW seems to be a good fit for this office. It offers Wi-Fi and gigabit ethernet connections, print and scan options from a mobile device, 70-page auto document feeder, built in NFC scanner for security access to the printer, as well as offering not only black and white printing but full color. Bandwidth and Devices: With our higher speeds coming from MetroNet, the bandwidth and latency speeds should be more than adequate to support multiple video conferences. When looking at devices for conferences, I would suggest the Logitech BCC950, as it offers premium

features at much lower prices compared to other options. Coming in at $250, this device has integrations with Webex, Zoom, and other conferencing programs, has an 8-foot microphone range, provides full duplex speakerphone and HD video all in a small size. Potential Errors When considering the proposal for this new office, we also need to future and error proof as best as we can. There can be many issues that arise, including slowing down of the internet speeds, DNS issues, Cyber-attacks, internet outages and potential VPN connection problems. The majority of network

complications can typically be traced back to a misconfiguration, but we still must diagnose the issue and find the source. Make sure our network and IT personnel are up to date on current network techniques and practices. Weekly and/or monthly maintenance is going to be key to making sure we stay on top of our network before it can cause larger problems. While we maintain and keep everyone updated on proper practices and how to avoid certain mistakes, it will keep the office running smoothly and allow us to resolve most issues in a timely manner. Additional Considerations Looking into network monitoring, we have quite a few selections to choose from. The top choice among them seems to be SolarWinds Network Performance Monitor. It comes with many different features such as a traffic analyzer, bandwidth monitoring, and it all comes packaged in a nice user- friendly interface for easy tasking. Other things we would be using are application and service monitoring, packet analysis, intrusion detection and network connection monitoring. Network intrusion is a fairly common and troublesome situation, and using SolarWinds we will be able to maintain and monitor our incoming and outgoing traffic to keep things buttoned up and secured. Introducing a patch management system will make things much easier when we need to update many systems at once. SolarWinds comes with a TFTP server, which I believe would be sufficient for maintaining patches and updates throughout the network and office. As for inventory control, again, SolarWinds with its many applications, also comes with a multi-vendor network inventory control system. SolarWinds Network Configuration Manager (NCM) can help you maintain an accurate, up-to-date inventory of your network devices and minimize the time you spend compiling and updating device information. You can use Network Configuration Manager to automatically import and discover devices and obtain detailed inventory information. You can also create network inventory reports based on

vendor, location, device type, device data and more and set up regular scans to help ensure data is updated automatically.
