Leonard Cooper Charter School LAN
Leonard Cooper Charter is a K-12 school that is in need of a local area network that will benefit them greatly. They have approximately 1,000 students, and they have had many complaints about the speed and function of their present network. A few years back they had a new section added on to the school, and this is when the problems began. To best suit them, a number of stakeholders have gotten together and voiced their concerns regarding the problematic areas such as the printing collisions, network and connection issues, and what type of cable would best to use to fix the problems, and they have addressed them to me so I can come up with a solution that will benefit the school.
The overall goal here is to plan, design, and implement technology that will definitely improve the teaching and learning within the school as well as prepare students with the best learning experience needed. The first area of concern I want to address is the print server. There were many collisions with printing within the school and it needs to be managed somehow. The school is currently using a half duplex system when they need to be using a full duplex system, because with half duplex systems, you can only communicate one direction at a time. “Nodes sharing a half duplex connection are operating in the same collision domain. This means that these nodes will compete for bus access, and their frames have the potential to collide with other frames on the network. Unless access to the bus is controlled at a higher level and highly synchronised across all the nodes co-existing on the collision domain, collisions can occur and real-time communication is not guaranteed”. (Liu, J. 2000) So no mater how many jobs that they try to do, without a full duplex system, things will always collide, making it complicated for printing processes to
