ANSWER ALL QUESTIONS

This report is about to design a wired and wireless network for a luxury residence hall at the University of Houston. The residence building has 8 floors that include 162 one bathroom and two-bedroom apartments from floor three to floor eight. Rest of first and second floor are used for office and management. At the first floor, a lobby is there having separate office area and a sitting area. The second floor has a meeting room. Both first and second floor are smaller than the other floor because of a parking garage is built around these floors. Both floors are having 100 feet by 70 feet covered area only. Further, 3rd to 8th floors are having 240 feet by 150 feet area. A server room is situated at the first floor for administration purpose. It manages all residence of the university. We are tasked to design a local area network for the whole building. In which the we need to keep the administration unit into a separate network subnet for additional security. The designed network will consist of backbone layer and distribution layer devices, used in the building with a detailed description of physical network topology and used devices.

FLOOR 1

A proposed network design for first floor, is presented in the figure below. The floor has a server room, where all the networking devices are placed in an MDF unit. It contains all the routers, switches, firewall and three servers. We use cisco’s N-tier hierarchical model in this design (Academy, C., 2020). At the starting of the network, a core router is installed which connects internal network to the internet. This core router connects a distribution router that further connected with an access switch. This access switch provides wired connectivity to the entire floor and connects access points. A firewall is installed at the starting of the network, between distributed router and switch to protect the network from intruders. Three racked servers are installed here and configured as Active Directory Server 1 (AD1), Active Directory Server 2 (AD2) and Print Server. All three servers are connected via wired connection in the MDF unit. AP 1 works on 2.4 GHz channel and provides wireless connectivity to visitors and AP 2 works on 5 GHz channel and provides wireless connectivity to employees and residences.

FLOOR 2

A proposed network design is presented below for floor 2. The floor network starts from the access switch, that provide wired connectivity to the floor. This connects all the wired systems at the floor and both the access point 1 and access point 2. The access point 1 (AP1) is configured to use 2.4 GHz channel and provide Wi-Fi connectivity to the visitors and access point 2 (AP2) is configured to use 5 GHz channel and provide wireless connectivity to Employees and Residences.

The IP addressing scheme used in the network design, is presented here.

FLOOR 3 –

A proposed network design for third to eight floors is presented here. As describe in the instructions, the same network design is being used for third to eight floors. All has two wings at each floor i.e. west wing and east wing. Both wings have an access switch for wired connectivity. All wired systems are connected to this access switch of each wing. An access point (AP1 at both wing) working on 2.4 GHz channel, is installed at each wing to provide Wi-Fi connectivity to visitors. Another access point (AP2 at both wings) working on 5 GHz channel provide Wi-Fi connectivity to employees and residences at that floor. The IP addressing table used in third to eight floor networks are also presented with the floor diagram.

DEVICES USED:

 Here is the detailed list of devices used in designing of this network.

• Router – The Cisco’s 4221 ISR (Integrated Service Router) router in our configuration. This category of routers is beneficial to be used in future upgradations just because of its digitally ready platform, capability of intelligent networking. These are also sustenance improved performance of network and better data transfer bandwidth with scalability and flexibility. Another useful benefit of this router includes, support of cisco intent-based networking, DNA architecture (digital network architecture), support of VoIP devices, easy to maintain and price effective (Services, P. and Routers, B., 2020).

 

• Switches – The Cisco’s 2960, 24 and 48 port catalyst switches are used in this configuration to deliver wired connectivity to the devices like workstations, IP phones, access points (APs). These are top layer 2 edge category switches that deliver better-quality and highly protected operative bandwidth with enhanced sustainability. This class of switches is originated from the series of stand-alone switches that has fast ethernet connectivity and can deliver 1 Gb pluggable uplinks. These are capable to provide fast wired connectivity that satisfy our network requirements (Support, P. and Switches, C., 2020).

 

• Wireless Access Points – We use Cisco’s Aironet 4800 wire-less access point (AP) in our network designing, to deliver connect wire-less devices. Aironet 4800 is a better performing and highly secured equipment that provide better network throughput with-out decreasing performance of the network. Aironet has a smart capturing feature that usage Cisco’s DNA center for in-depth examination, in-built hyper positioning feature, supporting self-issue detection and emanates with four in-built antennas to deliver better speed in Wi-Fi connectivity. Aironet 4800 delivers 2.6 Gb per second data rate with its each antenna with support of 802.11ac wave 2 support and compatible of both 2.4 GHz and 5 GHz radio bands that are capable of covering the entire office floor (Services, P., Points, A., Points, C. and Sheets, D., 2020).

 

• Cables – We use category 6a cables (CAT6a) to provide wired connectivity to the designed network. CAT 6a is an upgrade type of CAT 6 cable standard which is capable in delivering up to 10 Giga bit wired connectivity at the distance of 100 meters. This cable type supports up to 10 Gb per second data rate at a standard band-width of 500MHz with its feature of alien cross-talk. This feature allows to run the 10G-BASE-T standard to the distance of 100 meters. So, it is sufficient to provide the enough bandwidth to support our daily used applications (com.au, 2020).
