Computer Networking 4 Project Outline USD253 is a school district located in Emporia, KS. Current enrollment is 4500 students with roughly 600 staff members. The district contains 13 separate buildings that each have their own resources. Students and staff are each assigned a laptop to utilize throughout the day. A distributed network would benefit the school district in many ways. Allowing the clients access to shared resources internally and externally would be a great asset to their learning as well as a tremendous cost savings for the district. The ability for client machines to talk to servers, printers, and other network-attached devices would increase productivity and offer an increase opportunity to learn. A distributed network would be a great addition to the district.
Computer Networking 5 Distributed Network Requirements Analysis As a company grows, it often becomes necessary to expand the IT infrastructure. A major component of the expansion is the network. The network plays a pivotal role in allowing the ever-expanding infrastructure to provide communication among various nodes. Another advancement that coincides with an expanding organization is the need to offer centralized services that are accessible from various locales. Organizing a distributed network provides the backbone that allows for distant nodes to connect to an organization’s resources. This provides a level of flexibility and protection that is not available in other structures. For a distributed network to be effective there are several areas that must be addressed. It must be reliable, scalable, cost effective, flexible, and secure. Reliability For a distributed network to be reliable it must be accessible regularly to the organization. If a resource is frequently unavailable, it reduces its effectiveness as well as the trust users have in the system. The inability to maintain a reliable network, it could lead to corrupted data, inaccessible systems, as well as duplicate data if systems are unable to sync when needed. Without the ability to maintain the reliability of a network, the rest will become a moot point.
