The network topology that will be used in the Adelphi building will be the star topology. The benefit of using the star topology is that even if one node goes down, the rest of the network will continue to be up and running. Also, even though it requires more cabling than other topologies, it’s easier to add or remove computers to the network. In order to connect the computers and network devices to each other, we will be using Cat6 UTP cables. Cat6 cables provide faster speeds than Cat5 or Cat5e cables and support distances up to 100 meters. The only exceptions will be the Admissions office and classroom #6 (above Admissions office), which are right outside the range of Cat6 cable maximum lengths. For the classroom #6 and the admissions office we will use multi-mode fiber optic cables with an SC-type connector that will connect to a StarTech 1000 Mbps Gigabit Multi Mode Fiber Ethernet converter.
The network will include a Cisco Small Business 200 Series Gigabit Switches in each of the instructional computer lab servers (six total).
The switch contains 24 ports, 2 uplink ports, and supports speeds of 10/100/1000Mbps. It also provides support for VLAN, which can be used to group instructors and/or staff together. For the student computer lab additional ports are required and therefore we will use a Cisco Catalyst 2960-48TT switch. The switch contains 48 ports and supports the same speeds of the switches that will be installed in the instructional computer lab servers. One of the benefits of the Cisco catalyst is the network security through different methods such as ACLs (access control lists) and admission controls based on users, ports, and MAC addresses. Lastly, the server on the first floor will have a Cisco Nexus 3172TQ switch that can operate at speeds of 100Mbps, 1Gbps, and 10Gbps. The Cisco Nexus switch will be connected to the other servers and will support the connectivity for our fiber optic connection to the Admissions office and classroom #6. All of the computers connected to the switches will be using Cat6 Ethernet cables.
The Essay on Switched Networks
Networks are getting more and more popular, and because of this more people use them, which slows them down. Networks in the future will need to have enough bandwidth to support applications, like multimedia, witch require larger bandwidth. Switching will change the way networks are designed. These changes will maximize productivity. Switching technology is increasing the efficiency and speed ...
The only wireless access point will be located in the student lobby on the second floor. The wireless service will be provided by a Cisco Aironet 3700 Series Access Point that is connected to the server in the Student Computer Lab. The device supports the new IEEE 802.11ac standard which provides speed rates of up to 1.3 Gbps. The device will be setup to use WPA2 (Wifi Protected Access) and AES (Advanced Encryption Standards) for security purposes.
In the main server on the first floor we will install a Cisco 3925E Integrated Services Router. The router provides many security features such as zone based firewall, IPS, VPN encryption, etc. Many of the features will assist in protecting the network from intruders and/or attacks.
The servers installed will be Lenovo ThinkServer TS440 running Windows Server 2012 R2 OS. The hardware includes standard interfaces and devices such as HDD interface SATA and DVD-R. Windows Server 2012 R2 maintains the same features of Windows Server 2008 that will assist the administrator in managing the network in the office. In the new building the administrator will configure and manage 802.1X Authenticated Wireless Access for the wireless access point in the student lobby. Also, they administrators will manage the Active Directory and enable users to sign on from devices associated with the University’s Active Directory. The Group Policy feature in Windows Server 2012 R2 allows the group setting and group policies to be configured. Windows Server provides many other services such as DHCP and DNS servers that will also need to be configured and managed in the network at the new Adelphi location.

By: Chris Im 1. A network consists of two or more computers that are linked in order to share resources such as printers and CD-ROMs, exchange files, or allow electronic communication. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. 2.LAN- Stands for local area network. This is usually confined to a small space such as a ...
The workstations provided for the students, staff, and instructors will be Dell OptiPLex 462-3585 Desktop PC with an Intel Core i5 3.20GHz processor, 8GB DDR3 SDRAM, and a 1TB HDD. It will come installed with Windows 7 Pro and Microsoft Office 365 for students, instructors, and staff. Also, there will be 9 printers installed which will be installed as follows: each computer lab and the student computer lab will have one printer; the library will have one printer; and the admissions office will have one printer. Instructors will be given access to use printers at all locations. The printers will be Brother MFC Series All-In-One Laser printers that will be connected thru Ethernet to the network servers but will have the wireless print feature disabled due to security concerns. The device will be managed and configured to print for authorized users only.
