Washington School District Project

The Washington School District's Network Upgrade Project aims for significant enhancements in connectivity, including a 100x growth in LAN capacity, 2x growth in WAN connections, and a 10x increase in internet accessibility. This initiative encompasses three regional hubs and targets a total of over 10,000 connections. Infrastructure improvements will employ advanced technologies like Gigabit switches, routers, and modern protocols, ensuring compliance with security policies and integrating various district services. The upgraded network is designed to support a growing number of users, classes, and educational services.

  1. Washington School District Project

  2. Present State of Network General Requirements: • Functional =7-10 Years • 100X Growth in LAN • 2X Growth in WAN • 10X Growth in Internet Connectivity Initial Assumptions: • 1 Mbps Hosts • 100 Mbps Servers Protocols Allowed = TCP/IP and IPX

  3. Present State of Network Number of Users: Region Hub 1: One District Office/Data Center [75(A)+11[250(C) + 75(A)]=3650 connections Region Hub 2: One Service Center [75(A)+11[250(C) + 75(A)]=3650 connections Region Hub 3: Shaw Butte [11[250(C) + 75(A)]=3575 connections Total = 10875 connections Each Class Room is 24 Student + 1 Teacher = 25 connections Per Class rooms With 250/25=10 Class rooms Need Wiring

  4. Wan Connections To Meet Requirements: • 2X WAN Core DS3 • 10X Internet DS3 • Frame Relay with Backup PVC’s

  5. Local Area Network & Wiring Scheme R. E. Miller

  6. Local Area Network & Wiring Scheme

  7. Local Area Network & Wiring Scheme • Gigabit Switches Available for backbone From Switch to Switch • MDF 5500 Chassis Router • Extra - We have decided to put in a WIC Card for integrating the PBX to create a uniform dial Plan ability ( 4 Digit Dialing) • (100X) Growth in LAN Criteria has been met

  8. District Supplied Servers and Functions 6 Services Per School & District Offices • DNS • DHCP • SNMP • Administrative • Library • Application At District only • TFTP server • Larger Scale servers Each Server will have its own backup service Enterprise Class Servers • DNS, DHCP, E-Mail • Application • Library Server Workgroup Class Servers • SNMP, HP-Open view • Administration • TFTP

  9. District Supplied Servers and Functions

  10. Security USER ID and PASSWORD POLICY 1. USER ID ·        First six digits of last name, First initial of first name, number ·        (SmithJ1, SmithJ2, JohnsoM1) 2. PASSWORD ·        Maximum Password Age – 30 days ·        Minimum Password Age – 30 days ·        Minimum Password Length – 8 characters ·        Password Uniqueness – 12 ·Account Lockout

  11. IGRP • stable routing in very large or complex networks. (No routing loops) • fast response to changes in network topology • low overhead • splitting traffic among several parallel routes taking into account error rates and level of traffic on different paths

  12. Addressing and Management Using Class B Addressing 3 Subnets • Router gateway • Administrative • Curriculum 2 Subnets Unused Static addressing for Administrative Subnet Curriculum addressing will be provided by VLAN and DHCP Borrowing 8-bits will allow for up to 254 usable with subnet masks of 255.255.255.0
