District LAN
Requirements
The Washington School District Local Area
Network (LAN) requirements call for two LANS set up at each school. One will be
an administrative LAN with 75 users set with static IP addresses. The other
will be a 250-user student/curriculum LAN with access to the Internet and
e-mail. The addresses will be dynamically set for this LAN.
Both will have a cable infrastructure complying with EIA/TIA 568 standards, consisting of Ethernet 10BaseT, 100BaseT, and 100BaseFx. The vertical (backbone) cabling will be multi-mode fiber from the MDF to the IDF(s). The number of Intermediate Distribution Facilities (IDF) will vary at each site depending on the individual school’s building layout All sites will have one Point of Presence (POP), and one Main Distribution Facility (MDF), usually in the same location.
The MDF will house each school sites routers, connected switches and servers. It may also contain the switch for the administrative area if it is located close.
The LAN infrastructure will be Ethernet Switched based, extended star topology. There will be lockable cabinets in the classrooms with micro-switches. The available bandwidth will be above what the requirements are asking for. Below is a table of bandwidth requirements and the maximum available bandwidth available for the individual bandwidth specifications for general site negotiation.
Location |
Bandwidth Requirements |
Max. Bandwidth available with the recommended equipment |
|
Classroom Student/Curriculum |
100 Mbps total (Min. 1MB per drop) |
400 Mbps total. 100 per each of the 4 Micro switches per drop in the classroom. |
|
Individual Drops Student/Curriculum |
1Mbps |
200Mbps per student (full-duplex switching of 10/100 ports). If everything is running full it would be 16 Mbps. The 100Mbps from the uplink to the IDF. |
|
Administrative Individual Drops |
|
200Mbps. Each administrator will have access to a 100 Mbps switch port. |
|
Servers on site |
100Mbps |
Each server will have a connection to a switched 100 Mbps port on a switch connected to the administrative router for a full-duplex theoretical possible of 200 Mbps. |
Each classroom needs a minimum of 100Mbps. There will be a maximum of 4 CAT5e UTP runs for each classroom for the curriculum/study network. Each run will from a switch in the MDF/IDF to the uplink of a switch in the locked cabinet of the classroom. . Ports will be connected to wall drops in the classroom using decorative molding. A separate CAT5e UTP run will be made from the switch in the MDF/IDF for the instructor.
