Network Infrastructure: This project will require replacement of major networking components throughout the office. Virtualization will result in increased speed and reliability for employees. Current business needs revolve around making our company more efficient. Efficiency is currently held back due to aging and obsolete network components. These issues are highlighted by specific problems employees are experiencing such as slow network connections, spotty wi fi coverage within office building, and the fact that the current server has reached maximum capacity, no longer allowing any further users to authenticate with it. Opportunities with this project are summarized by increased efficiency for employees which will result in greater productivity. These upgrades, if met with a successful implementation plan should translate to increased satisfaction with our customer base and the capacity to add to that base, making the company more profitable in the long run. Details of the proposed infrastructure upgrade are as follows. Changing of the current backbone wiring to fibre optic cable will improve data transfer speed capabilities. Replacing hubs with switches will allow each individual network card to transmit data simultaneously rather than waiting its turn. Improving wi-fi coverage through the use of higher spec routers will increase the coverage and significantly reduce the likelihood of dropped connections. By upgrading the current servers we will expand the capacity of our network, allowing more users to authenticate. Problem: Issues with implementing this project include the downtime endured while the network is upgraded. When the components are being replaced the communications within the company will be significantly hindered. Therefore it is imperative that we have backup systems in place so that we can still utilize effective communications.
