Download - Dunlap Network Update
Our Data Network…A challenge and an opportunity for improvement!
Background Information
• Growth, growth and more growth!– Steady increase in student population– More schools, more staff and more technology
• The focus on 21st Century learning has created a demand for ever increasing bandwidth for multimedia resources.
• The district’s current network design is based on Cable modems – “Shares” bandwidth with other companies or
residents in the local geographic area
• We’ve outgrown our network!
• Slow downs, time outs & network issues
• Email, web pages, food services data, student information system, finance and payroll, and others are barely working.
• Outside users (parents, community, etc.) are frustrated with the time it takes to access District resources.
• District served by Comcast and Mediacom
• Powerschool is struggling to function
What’s the Problem?
How Big of a Problem is It?
• From a site within the district, it took longer than 5 minutes to load:– District Web Site– High School Web Page
• From outside the district, it can take as long as 15 minutes to load (during the school day)

Finding Solutions• Multiple solutions were
researched :– Build a fiber network to all schools– Upgrade existing cable modem network– Purchase circuits such as T1 lines– Point to point wireless
• Selection criteria included:– Cost of implementation/installation– Monthly/recurring costs– Timeliness of implementation– Scalability– Meet needs now and in the future
Recommended Solutions• 1.) Upgrade the main internet
connection for all outgoing and incoming network traffic.– Current: 2 Megabit up and 20 Megabit down on
a cable modem connection– Proposed: 50 Megabit up and 50 Megabit down
on a fiber network connection (Mediacom)
• 2.) Upgrade the connections between each site to handle network traffic.– Current: 2 Megabit up and 20 Megabit down on
a cable modem connection– Proposed: 125-300 Megabit up and 125-300
Megabit down on point to point wireless system
• DMS or DVMS to serve as the “hub” for point to point wireless connections
• Connection speeds of 125-300 mbs• Currently, we have 2mbs between schools
DMS Rooftop
DVMS Tower
200 Ft.
Location of Wireless Antennae
Estimated 30-40 feet higher than roof of DMS
Fiber Optics• Install fiber
between DHS and DGS
• 1 gigabit connection
• Basically the same cost as installing wireless
Fiber Connections
Estimated Cost
• One time cost for equipment and installation= $143,000
• Additional monthly costs for increased internet bandwidth= $1350 month
Questions and Next Steps
•Need consensus from the board to move forward (not an action item)•If we can act now, we can implement the solution by mid-July
