IT Risk Management
Case Study: Network Topologies Research
You have been asked to help upgrade the LAN at a very successful ABC firm with five departments in one building and a total of 560 employees. Although the firm’s employees understand accounting, they haven’t spent much time improving their network. Currently, it runs 10Base-T Ethernet and relies on 35 hubs to connect every user workstation to the network. Most of these workstations were purchased within the past two years, when the firm experienced a growth spurt. The hubs are connected to the backbone via switches. The CPA firm wants to upgrade its LAN, but not at great cost. It also wants to ensure that it can easily expand its LAN in the future. It has already decided to use a version of Windows 2008 as its network operating system.
What kind of LAN will you design for this company? Describe its physical and logical topologies, what access method it will use, and what Physical layer standard this access method should rely on. What types of infrastructure upgrades are necessary to implement your suggested network?
The ABC firm that has five departments in the building those all connected with LAN and total employees of 560, which currently runs 10Base-T Ethernet and relies on 35 hubs. These workstations were purchased in last two years, but they are experiencing slow network connectivity. Based on the current situation, they have decided to use Windows 2008 OS version.
Though, this firm has a limited budget, where the firm bought some hardware and software. The IT world uses very high-grade equipments through which we can integrate and update the existing network.
The below design shows the hubs which are upgraded by me to switches and these are much better than hubs. Each department has 112 employees and we got five departments, which are connected with one router. I recommend for this network that every department should have one
