  1. Network/Technology Infrastructure PlanSection 5 – 6 – 7 As prepared for the TUSD Governing Board Summer 2007 John Bratcher Network Security Systems Analyst

  2. Today’s Topics • Section 5 – Proposed District Standards • Section 6 – Emerging Technology Considerations • Sections 7 – Data Protection and Disaster Recovery

  3. Bandwidth Contexts 100 Mbps bandwidth on LAN 1 Gbps bandwidth on LAN 1.5 Mbps bandwidth on WAN 45 Mbps bandwidth on WAN Computer IDF MDF Hub Site Morrow Hub Internet 145 Mbps ISP Uplink

  4. Greater Bandwidth demands • Increasing use of streaming video • Increasing use of video teleconferencing and distance learning • Increasing trends toward 1:1 computing in K-12 • Increasing use of web-based (versus computer-based or textbook based) instructional materials. • Increasing use of IP-based voice

  5. Specialized systems that depend on the network Environmental Management Control Systems (EMCS) Fire Alarm System Security Alarm/ Video Surveillance System Access Control System Irrigation Systems Distance Learning Systems Conference Bridge System Remote Access (VPN) for staff and teachers (limited) TUSD Television Broadcasting System

  6. Bandwidth Current Bandwidth Elementary Schools 1.54 Mbps Middle Schools 1.54 Mbps High Schools 3.08 Mbps Recommended Bandwidth – based on average 50 Kbps/student Elementary Schools 100 Mbps Middle Schools 300 Mbps High Schools 500 Mbps Detailed “PER SITE” of calculations in Table C-2 of Appendix

  7. Proposed District Standards • Classroom configuration • Building configuration • District level configuration • Bandwidth Needs • Equipment replacement schedule • Disaster Recovery

  8. Infrastructure Standard for each Classroom: • 1 drop (6-12 strands) fiber optic cabling (rated at 10Gbps- operated at 1 Gbps) • 2 CAT5 Enhanced copper drops PoE • 1 for wireless Access Point • 1 for voice • Classroom data cabinet including 24 port managed switch (1 Gbps) • 8 CAT5 Enhanced copper data drops • APPROVED Standards – in packet

  9. Infrastructure Standard for each Classroom:

  10. Infrastructure Standard for each School Site • Adequate switching and cabling capability to support all classrooms at 1 Gbps • Uninterrupted Power Supplies to handle PoE requirements at all IDFs • Adequate electrical capacity • Adequate HVAC

  11. Infrastructure Standard District Level Current Bandwidth = 75 Mbps- 145 Mbps (E-rate) Voice – Converged but not fully IP enabled Variety of cabling and switching from CAT3 (10 Mbps) to CAT5 Enhanced (1 Gbps) Recommended Bandwidth – 1 Gbps upgradeable to 10 Gbps All voice systems –IP Enabled All cabling/switching to support 1-10 Gbps

  12. Targeted Needs: • Upgrade network hardware and bandwidth to support the network core, distribution and access layer connections • Upgrade all copper cabling to Cat 5 Enhanced • Installing LAN wireless access points to provide coverage in all learning areas • IP-enable PBX equipment • Install fiber optic cabling within and to all buildings on a campus

  13. Emerging Technology Considerations • IP-Enabled Voice systems • Establish the role of wireless • Support expressed academic technology needs: • Increased Capacity • Remote Access • Parent-Teacher Communications • Review of Special-purpose network services

  14. Data Protection and Disaster Recovery • Mission Critical • District information stored in electronic form that is reliable and automated • Procedures for recovery from possible disasters have been carefully designed

  15. Data Protection and Disaster Recovery Central Servers • Tape library is outdated • Technology is outdated • Capacity is inadequate • Process is inefficient • No off-site redundancy • Site Servers • • Tapes fail • • Tape drives fail • • Tape capacity is inadequate • • All data cannot be backed up • • Backups are recycled too quickly
