Existing Needs

The current Desert View LAN design plan assumes 58 fixed curriculum workstations, 49 fixed administrative workstations, and 192 portable curriculum workstations which could potentially be accessing the network at any given time. As described in the logical diagram and the cutsheet, each workstation is attached to a hub at the horizontal cross-connect. Each hub then uplinks to a switch port at the vertical cross-connect in each building, and each switch uplinks to the LAN switch in the main distribution facility. The quantity of switch ports used for the existing network is described as follows:

• MDF
  • 18 GBIC fiber ports. 18 in use.
  • 24 10/100/1000BaseT ports. 20 in use.
• VCC1
  • Switch 2 – 12 10/100BaseT ports. 11 in use.
  • Switch 3 – 48 10/100BaseT ports. 33 in use.
• VCC2
  • Switch 4 – 12 10/10/100BaseT ports. 6 in use.
  • Switch 5 – 24 10/100BaseT ports. 18 in use
• VCC3
  • Switch 6 – 12 10/100BaseT ports. 5 in use.
  • Switch 7 – 24 10/100BaseT ports. 15 in use.
• VCC4
  • Switch 8 – 12 10/100BaseT ports. 5 in use.
  • Switch 9 – 24 10/100BaseT ports. 15 in use.
• VCC5
  • Switch 10 – 12 10/100BaseT ports. 4 in use.
  • Switch 11 – 12 10/100BaseT ports. 12 in use.
• VCC6
  • Switch 12 – 12 10/100BaseT ports. 4 in use.
  • Switch 13 – 12 10/100BaseT ports. 12 in use.
• VCC7
  • Switch 14 – 12 10/100BaseT ports. 5 in use.
  • Switch 15 – 12 10/100BaseT ports. 12 in use.
• VCC8
  • Switch 16 – 24 10/100BaseT ports. 16 used.
• VCC9
  • Switch 17 – 24 100BaseFX ports. 8 used.

As described in the User Expectations Document, the network is expected to be functional for seven to 10 years, with expected 100 times growth in LAN throughput. This can be achieved by replacing the existing curriculum hubs in each classroom with a Cisco 2950T-24 or similar switch, then microsegmenting to dedicate 100Mbps to each workstation. A single 24-port switch can be placed in each intermediate distribution facility for all administrative workstation ports in the building. The quantity of switch ports that will be required is described as follows:

• MDF
  • LAN Switch – 18 GBIC fiber ports, 2 10/100 ports to router, 7 10/100 ports for servers, 4 ports for connections to VCC/HCC switches.
  • Building 3 West HCCs – 48 curriculum ports, 2 10/100BaseT uplink ports to 2 ports on LAN switch.
  • Building 3 West VCC – 15 administrative ports, 9 curriculum ports, 2 10/100BaseT uplink ports to LAN switch.
• VCC1
  • HCCs – 192 curriculum ports, 8 10/100BaseT uplink ports to 8 ports on IDF switch.
  • VCC – 11 administrative ports, 9 curriculum ports, 2 10/100BaseT uplink ports connectd to 2 ports on IDF switch.
• VCC2
  • HCCs – 120 curriculum ports, 5 10/100BaseT uplink ports to 5 ports on IDF switch.
  • VCC – 3 curriculum ports, 6 administrative ports, 2 10/100BaseT uplink ports connected to 2 ports on IDF switch.
• VCC3
  • HCCs – 120 curriculum ports, 5 10/100BaseT uplink ports to 5 ports on IDF switch.
