For most schools these core competencies are not cable engineering, networking architecture, telecommunications engineering, systems integration, hardware repair, network engineering, and software development. The network has continual problems throughout the years. The problems become so bad that the teachers write a memo to the school administration requesting that the network be shut down until it is fixed. After weeks of a systems integrator trying to get a school network running a cabling engineer is called in to test the cabling. The teaching staff at the high school is upset because even though there is a T1 connection getting on the Internet and getting to software can be unreliable and slow.
Network engineers find that the network has daisy chained stackable, shared hubs.
There is no concern for segmentation of the network and there is no high- speed backbone for the servers and other network resources. A district installs a network with in-house personnel. They have no mechanism for teachers to distribute files to students or for students to drop off files for teachers. There is no Internet filtering or virus protection. Viruses regularly disrupt the system.
