â€œYou Decideâ€ Charter School Scenario
This proposal is for an evaluation of the current network at Leonard Cooper Charter School, as well as a list of recommendations to address concerns raised by system technicians and end-users. Leonard Cooper Charter has roughly 1,000 students and faculty, all needing a smooth connection to the school LAN. A new addition was added to the building a few years ago, and has resulted in numerous IT problems for the school. Overall, stakeholders have indicated general dissatisfaction regarding network speed and reliability. Key areas of concern or desired revision that were noted include a large number of printers without an efficient or reliable networking management system; severe bottlenecking during high-traffic times; effective means of managing equipment through the web using the LAN ...view middle of the document...
Currently, the network bandwidth has a small capacity, at only 10Mb. By upgrading to Fiber 1000Based-F Ethernet cabling, the capacity can be increased to 100Gb/sec. This will resolve the bottlenecking that occurs during the high-traffic morning hours when teachers are submitting attendance and checking their e-mails. A slow connection to the e-mail server was also reported, which would be remedied by the higher bandwidth connection provided by the Ethernet cabling.
There is then the issue of the twenty-three additional computers in the new wing that are currently not connecting to the network. The old and new wings are connected via twisted-pair wiring, which will not support the additional demand on the network. The new backbone network should be converted to a fiber optic. This will not only clear the current congestion, but will also allow for the additional computers on the network without creating bottleneck issues.
The upgraded network will also allow for the remote access to the HVAC equipment that was requested by the HVAC technician. For wireless access and maintenance of the HVAC equipment, a radio wireless signal should be used. Wireless access points should be installed, in addition, wherever line of sight is broken. This will help to prepare for future expansions to ensure that accessibility and dependability of the connection.
Finally, a dedicated print server is needed to clear the too-quickly filling printer queue. At minimum four additional 24-port hubs should be installed to connect existing printers under the Ethernet bus topology. Two hubs should be located between the administrative offices, where the majority of the traffic is coming from, and two should be located beside the new backbone for the new wing to accommodate any additional printers that may be installed.
