Network Design Proposal Prepared for: University of Maryland University College Prepared by: Amanuel Abebe

[3]

I. Network Design A.

Network Topology As we all know University of Maryland University College has recently leased a single

building, this building will house facility and administrative offices, classrooms, library, and a computer lab. As the university makes this big change, we need to make sure there is a popper network infrastructure that provides security network for the newly leased building. In this case the best network topology is the star topology. Starts apology is designed with each node (computers, printers, any other device connected to the network) connected directly to a central network HUB, switch or concentrator (). Below is brief diagram that shows the concept of Star topology. Fig 1. Star Topology diagram (made using https://www.draw.io)

Justification

[3]

There are several reason and benefits don’t make the star of apology the best solution for the university of Maryland University College newly leased building. Some of the main reasons why the star topology is preferred are listed below: 

When using Star topology connecting new nodes or devices to the existing network is very easy compared to the rest of the topologies.



When one node is disconnected from the network it does not affect the rest of the network connections.



When compared to the other topologies, installation is fairly easy



When using Star topology, troubleshooting and fixing network connections is easy because the detection takes less time.



B.

Star topology allows network redundancy and resiliency

Cables and Connectors

When implementing Star topology, the cables and connectors we chose play a vital role in making sure in making sure there is a high-speed connection between the server and other devices. I would recommend the use of multi-mode fiber to connect the servers and the use of Cat6 shielded twisted pair (STP) cables to connect hosts to the network. Diagram ( to the right) that shows how these cables will connect to different devices throughout the new building. Fig 2. [1]

Justification

[3]

Multi-mode fiber optic cables are capable of providing 10Gbps transmission. Information that travels from the intermediate distribution frame (IDF) to the main distribution frame (MDF) will be able to travel with ease. Cat6 shielded twisted pair (STP) cables provide high speed data transfer. The Cat6 STP cables reduce the potential of electromagnetic interference [2].

Justification The networking hardware listed above is necessary in order to accomplish the network proposal. The router listed will be used to link the devices to the network. The 8-port switches will come in handy to extend the networking system throughout the new building. The server and switches will manage connection on the entire network.

D.

Wide Area Network (WAN) Design

The wireless routers will provide users access to the network. When faculty and students use their BOYD to accomplish any task on the network they will be utilizing the routers installed. As

[3]

listed in the table, we will be using Aruba Networks Instant AP-207 Wireless Access Point will be used for the WAN. As listed in the table we are going to install four total wireless access points two on both floors. Justification When both students and faculty use their BOYD in the new building they are going to access the network using WAN. I have selected Aruba Networks Wireless Access point because the integrated BLE and supporting 802.3af power, the Aruba 207 Series AP enables enterprises to improve their work efficiency and productivity with the lowest TCO [4].

E.

Computer Systems Hardware

The newly leased building will have to accommodate computer access for both the students and faculty. The computer will be used in classrooms, labs, library and different offices located in the building. The computer should be able to handle variety of tasks such as word processing, creating database, and processing various tasks online through the network.
