Technology: Doing More With Less Presented by Glen Popiel MDE/CIBER Network Engineer CCNA, CNE, MCSE, Security+ MDE/CIBER Inc.
Problem #1: We have no money • Budget reductions are affecting State and School District budgets. These can be expected to continue • To improve the quality of education, we need more technology in the classroom • Technology comes at a price, in terms of hardware, software, support costs and manpower MDE/CIBER Inc.
Problem #2: We have no bandwidth • More and more applications are moving to an online web-based format instead of being locally hosted as in the past • Internet bandwidth usage is growing exponentially and there is not enough bandwidth to support these applications • Each application moved online consumes additional bandwidth which is only compounding the problem MDE/CIBER Inc.
Bandwidth Availability • • At the state level there is 1, 200 Megabits per second of bandwidth allocated to the K-12 MPLS network Usage by ALL districts MUST average 7. 9 Mb/s 1791 Mb/s is allocated by the state to the district offices alone – We’re 591 Mb/s short before we even include the schools into the equation – The only reason this works is typical Internet data is not constantly streaming but is intermittent bursts of data • However, more and more of our Internet usage is streaming data (video, etc) Increasing the bandwidth at the district/school level doesn’t gain anything since the bottleneck is effectively at the state level MDE/CIBER Inc.
The Laws of Physics are still being enforced • Bandwidth demand cannot exceed bandwidth available – We’re already negative 600 Mb/s at district offices alone – The move to more streaming Internet content is stretching this to the breaking point • Since neither Stephen Hawking nor Albert Einstein are working on this problem, we’re basically on our own MDE/CIBER Inc.
At The School Level • The average school is connected to the Internet via a single 1. 5 Mb/s T 1 circuit • Assuming the average student online learning session consumes 300 Kb/s and contains streaming content, each school can have about 5 students using any of these applications at a time with NO bandwidth available for other Internet activity • Even if the school is not connected via a T 1, the overall 7. 9 Mb/s average per district still applies MDE/CIBER Inc.
Application Bandwidth Usage • • • • STAR Early Literacy : 32, 790 Kb/s English in a Flash : 14, 450 Kb/s Fluent Reader : 12, 390 Kb/s Accelerated Reader : 9, 027 Kb/s Math. Facts in a Flash : 6, 178 Kb/s STAR Math : 5, 825 Kb/s Accelerated Math : 4, 333 Kb/s MPB/Distance Learning : 3, 000 Kb/s Streaming Video : 3, 000 Kb/s STAR Reading : 2, 929 Kb/s Compass/Odyssey : 2, 560 Kb/s (HS) 1, 280 Kb/s (K-8) Plato : 1, 280 Kb/s Streaming Music : 1, 280 Kb/s • • • Based on 10 concurrent users T 1 Bandwidth = 1, 544 Kb/s Based on estimates provided by software manufacturer MDE/CIBER Inc.
Problem #3: We’re not getting all the bang for our technology bucks • Implementation of Online Applications we don’t have the bandwidth to support • Implementation of new technology we don’t have the network infrastructure or personnel to support • Technology staff is not being involved in purchasing decisions – Not enough manpower to support – Network infrastructure insufficient – Bandwidth not available – Cost of support not considered • Vendors tend to sell what they want you to buy not what you really need MDE/CIBER Inc.
There Are Solutions • Bandwidth options • Smart technology purchasing • Virtualization • Free Stuff • Other Cost Savings MDE/CIBER Inc.
Bandwidth Options • Conserve Internet bandwidth – Content Filtering can help but it’s a band-aid – User education to reduce bandwidth waste – Don’t use online backup services such as i. Disk, Carbonite, etc. They can transfer huge amounts of data – Implement local Windows Update and Antivirus update servers • More Bandwidth – But I said there’s no bandwidth available • Consult with your technology staff, MDE and the CIBER reps for possible solutions • Host your Applications locally – Adds to hardware and support costs MDE/CIBER Inc.
Buy Wisely • Do you really need what you’re planning to buy? – Is there a more effective solution available at a lower overall cost? • What are the TRUE bandwidth and infrastructure requirements? – Do you have the bandwidth to support it? – Single User demos always work great. You have to scale it to the planned number of users • Can your existing tech staff support it? – Will it require additional infrastructure and/or manpower? MDE/CIBER Inc.
Alternative Solutions • Moodle • Virtualization – server and desktop • Firewall, VPN, Content and Spam Filtering • Voice Over IP Phone/Intercom/Bell Systems • Google Apps • Open Office • Open Source Learning Applications MDE/CIBER Inc.
Moodle • Moodle is a FREE Open Source Course Management system allowing teachers to create their own course content in an online environment that is hosted locally • Because it is hosted locally, students and teachers can use Web 2. 0 technology in a closed, secure, safe and managed environment • Thousands of teachers have already created content you can use immediately in the classroom MDE/CIBER Inc.
Virtualization is the latest technology trend that allows for reduction of physical equipment while providing the same level of functionality to the end user • Server Virtualization – Allows the consolidation of server hardware to fewer physical units, reducing long term costs – The software required to do this is free • Desktop Virtualization – n. Computing/Thin Clients – Significantly reduces the cost and number of physical workstations required, replacing them with just a monitor, keyboard, mouse and a thin client device MDE/CIBER Inc.
Firewall, VPN, Content and Spam Filtering • Clark. Connect/Clear. OS is a FREE Open Source Content Filter, Firewall, VPN and Email Spam Filter solution which performs as well as expensive commercial solutions. – Some commercial solutions actually use customized versions of the same software components in Clear. OS in their products. – Already used in over 100 Mississippi School districts – Fully CIPA compliant – Includes a Helpdesk Ticketing System • Commercial filtering solutions can cost $5/yr per user or higher • MDE/CIBER provides training and FREE support MDE/CIBER Inc.

Other Savings • Substantial savings can be gained by turning off the power on your workstations, etc. at the end of the day – Easily implemented and can be cancelled by a user working late • The average compact refrigerator costs $21. 25 per year • Not only do space heaters pose a significant fire hazard, they use a lot of power and put an unplanned load on the school’s electrical system, often overloading circuits used for workstations. A space heater can cost a district $54 each per winter. MDE/CIBER Inc.
Power Savings • In a district with 1300 workstations, simply by turning off workstations after hours, $2, 350 per month could be saved. Over a 10 month school year this adds up to $23, 500. • Based on 2007 -2008 MOTE survey data, there are 146, 874 workstations statewide. This yields a potential statewide savings of $632, 800 to over $3, 000 in wasted electricity costs. MDE/CIBER Inc.
