While they have a computer network and are  connected to the Internet. All of their computers are desktop machines and are connected with wired Ethernet  connections. All of the network wiring is CAT-6 twisted pair wiring that goes from the office location to a wiring  cabinet. There is one wiring cabinet on each floor. Each cabinet is connected to the basement wiring cabinet via  fiber.

The second floor has the Marketing department. There are a total of 15 employees in the Marketing Department  and includes Marketing executives and assistants. All of the marketing department personnel have laptop  computers, but they are still connected via the wired network. 

The first floor has the academic department, classes/training rooms and the receptionist. The receptionist shares  a computer with the administrative office. There are 24 people in academic department, they use 24 computers  to enter their academic records into the institute's current system. There is also a conference room/training room  on the first floor with a multimedia system that includes a podium computer, projector and all of the bells and  whistles. The basement houses the information technology and maintenance department and the mail room. The  mail room clerk uses one computer. The two maintenance workers have computers at their desks that they use  to enter reports of work performed. The IT Department has eight employees, each with a desktop computer.  

CODEC has planned to invest in their network Infrastructure and host their own web server and database server  and also decided to have internet connection with different ISP and load balance their Internet traffic and if one  ISP goes down other ISP should automatically take all the Internet traffic without any downtime.  

Also CODEC wants to implement a ICT Network Monitoring solution which provide in depth knowledge and logs  and traffic flow of their network. Additionally, VoIP as well as videoconferencing services when staffs are not able  to physically attend the meetings. CODEC wants to manage its own server farm, which includes two domain  controllers, one print server, one mail server, one database server, one internal web server, one external web  server (having the firewall), a file server, a special server for the ERP system, and a backup server. 

Now, your roles as Network Administrator to propose a network design suit for their needs.

Requirements to add Wireless Network Access Points (WAP) 

? Each floor, needs to have two wireless access points, one for the north end of the building, and the other for the south. 

? The wireless access points will overlap in the middle of the building, so you need to pick different  wireless network channels for each end.  

? On the first floor, there should be an additional wireless access point in the conference room. ? The ”guest” network should have a different SSID than the institute's wireless network. It should be configured to allow anyone to connect, with a password.  

? The password will be provided by the receptionist to any visitors and will be changed each week. The  institute wireless network should be configured to have the same SSID on all of the wireless network  access points (but different from the ”guest” network).  

? The “guest” network should be connected to the institute’s servers for authentication (Windows Server  enabled for the Active Directory). 

? Place your network access points on your network diagram.
