LAN Requirements:

  •  Internet access must be available from any workstation within the school
  • LAN implementation must be functional for a minimum of 7-10 years


Consideration of growth of LAN must be considered within designs:


  • 100x (times) in the LAN throughput
  • 2x (times) growth in the WAN core throughput
  • 10x (times growth in the District Connection Throughput.


Minimum requirement for initial implementation design is:


  • 1.0 Mbps to any host computer in the network
  • 100 Mbps to any server host in the network
  • Only two OSI layer 3&4 protocols will be allowed to be implemented in this network,
    they are TCP/IP and Novell IPX.
  • Two LAN segments will be implemented in Acacia school and the District Office


Transport speeds will be:


  • 10BASE-T
  • 100BASE-TX
  • 100BASE-FX
  • For horizontal cabling CAT5 UTP will be used and able to accommodate up to


  • For vertical cabling CAT5 UTP or fiber optic multi-mode cable will be used
  • LAN infrastructure will be based on Ethernet LAN switching
  • A designated LAN forstudent/curriculum purposes and another for administration
    purposes must be implemented
  • Future proof methods of wiring must be used so that the LAN can be revamped at a
    later stage
  • Each room requiring connection to the network will be able to support 24
    workstations and be supplied with four CAT 5 UTP runs for data, with one run
    terminated at the teacher's workstation
  • Acacia school is on Regional Hub II which means it will have to be able to support
    250 curriculum workstations and 75 administration workstations in the school


Severs to be implemented:


  • DNS/Email
  • Admin
  • Library
  • Application
