  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
