Project: Network Design for Science Building
Due Date: May 1, 2009

Building layout:
square, 120m by 120m, three-story building

1) first floor plan:
1-1) one auditorium, four outlets in the platform area, eight outlets in the control room, at least 10 of them should be activated
1-2) two classrooms, each has 60 student computers, one instructor computer and one network printer
1-3) one computer lab, 60 computers and two network printers
1-4) 8 research labs, each has 16 outlets, at least 14 outlets should be activated
1-5) reserve at lease 16 ports for future expansion
1-6) maximum of four wireless APs
1-7) South west corner room is the point of presence (POP, where network lines com into the building)

2) second floor plan:
2-1) four department offices, Physics, Chemistry, Biology, and Geology, each needs 12 outlets
2-2) 48 professor rooms, each need two outlets
2-3) four discussion rooms, each has one computer
2-4) maximum of four wireless APs

3) third floor plan:
3-1) Dean's office, 36 outlets, at least 30 activated, including one discussion room
3-2) Associate Dean's office, 24 outlets, at least 20 activated, including one discussion room
3-3) Career and Alumni's office, 24 outlets, at least 20 activated, including one discussion room
3-4) Student Services, 24 outlets, at least 20 activated, including one discussion room
3-5) Computing Services, 36 outlets, at least 24 activated, including one discussion room
3-6) Conference room, 48 seats, each has an activated outlet; two more outlets, one for the room computer; one conference VoIP phone.
3-7) maximum of four wireless APs

4) server room:
4-1) can be designed to second or third floor
4-2) two core switches and dual links to all branch switches; in short, no single point of failure on backbone links
4-3) ten servers each has two links
4-4) reserve VoIP server connections
4-5) ignore air condition and UPS design, but mention them in your project

5) additions
5-1) estimate voice over IP usage (one phone per room) and install the power of Ethernet switches accordingly
5-2) do not over-install wireless AP's, blind points can be patched later by small individual wireless zones
5-3) each classroom and discussion room has a ceiling-mounted projector that needs a direct RJ45 connection to the video adapter of the computer console in the front area of the room or in the control room
5-4) student computers in classrooms and third floor conference room 48-seat outlets cannot reach out of the college
5-5) management, faculty and staff vlans must be secured
5-6) use private IP for internal backbone connections where needed, otherwise estimate total IP needed plus one more class C (256 extra for expansion), all of them inside the 128.x.x.x range.
5-7) allow all outbound traffic to the Internet except 5-4) and allow only three IP's reachable from outside
5-8) wireless network should have its own vlan
5-9) Voice network should have its own vlan

Design tips:
(1) determine how many network ports are needed and how many of them should be PoE
(2) determine how many and what kind of network devices to be installed
(3) determine where the network devices should be located
(4) determine how many backbone links and how many patch panel ports ate needed
(5) determine how many IP's and VLANs are needed
(6) estimate bandwidth utilization and determine out-link bandwidth
(7) implement load-balancing on backbone devices
(8) implement access control list on the firewall
(9) estimate cost
