Solution to the Problems Affecting Leonard Cooper

solution to the problems affecting Leonard Cooper Charter School LAN

Network collision that slows down the network and interferes with print jobs

The problem of network collision is noted by Rouse (2006) to be most common in half duplex Ethernet network. The collision observed at the Leonard Cooper Charter School LAN is most likely caused by the two or more devices (printers and competing workstations on the LAN most certainly) attempting to effectively transmit data at al most an exact same time (such as sending a print job).The Leonard Cooper Charter School LAN therefore detects the collisions of the two or more transmitted packets as then effectively discards them. It is important to note that collisions are perfectly normal occurrences on the Ethernet networks.

Remedy

For the collisions to be avoided on the Leonard Cooper Charter School LAN, there is a need for the Ethernet to employ Carrier Sense Multiple Access / Collision Detect (CSMA/CD) as a technique of allowing the various devices on the network "taking turns" on the use of signal carrier line. Whenever any given network device wants to effectively transmit a signal, it would have to first check the signal level of the given line in order to determine if any other device is already using the given line. If the line is already in use then the device would automatically have to wait and then retry in lets say a few seconds to retransmit the signal. If the line is not engaged then the device would successfully transmit. If two or more devices transmit at almost the same time, a collision would occur with both devices detecting the collision. Each of the concerned devices would therefore wait for a random amount of time and then retry transmission until the signal is sent successfully. The best remedy for network collisions on the Leonard Cooper Charter School LAN is to engage in a network upgrade to a completely full duplex switched environment. The best equipment to use would be full duplex 24 port switches.

Problem 2: Failure to retrieve data due to overreliance on a slow 10 Mbit Ethernet and the lack of a wireless functionality

The best way of dealing with this scenario is to upgrade the Ethernet to a fiber optic based one using Category 6 UTP 1000 Base - T Ethernet Cabling. This would deliver a 1 Gigabit link that can be implemented using a Fiber 1000 Based-F and wireless hotspot routers.

Problem 3: lack of alive network connection port and the general lack of network expansion within the classroom (Lack of the ability to add extra devices).
