Networking devices
The Computer Center's LAN network design and infrastructure play an important role in ensuring seamless connectivity and effective facility operations. The networking hardware used in the Computer Centre, such as routers, switches, wireless services, email services, and various system servers, are examined in this essay along with their suggested fixes.
To build a strong and dependable infrastructure, the LAN network design involves a number of essential networking components. The high-performance Core Switch, which is located at the centre of the network, serves as the primary point of connection, facilitating effective data transmission and acting as the network's backbone. The Computer Center's numerous network components can communicate easier thanks to this switch. Each device maintains its connection to the hub independently, so the failure of one link does not disrupt the overall network.
Distribution Switches, which manage local network traffic and connect to end devices on their respective levels, are located strategically on each floor of the Computer Centre. These switches improve network performance by reducing the network and efficiently handling network traffic.
To allow connection between the LAN network of the Computer Centre and other networks, including the Internet, routers are used in addition to switches. For effective data transfer and to protect the security of the internal network, routers simplify traffic routing and provide correct network segmentation.
Wireless Access Points (APs) are used to integrate wireless services into the network backbone. Users can connect their devices wirelessly and access network services without being constrained by physical wires due to these devices, which provide wireless connectivity throughout the Computer Centre.
System servers are set up in the Computer Centre to support key services. The facility's efficient handling and delivery of emails are made possible by the Email Server, which manages email services. While the Staff Information System (SMSM) Server stores and manages data connected to staff, the Student Information System (SMP) Server does the same for data related to students. The ULearn Server hosts the online learning platform for students and staff, and the Financial System (SMKB) Server manages financial transactions and accounting.
In conclusion, the Computer Centre's LAN network design and infrastructure use a variety of networking tools to create a dependable and effective network. A seamless connection, effective data transfer, and effective administration of network resources are all made possible by the routers, switches, wireless services, email services, and system servers utilised by the Computer Centre. This strong network infrastructure supports the facility's efficient operation and improves user interaction and information sharing.
Topology
The Computer Centre's LAN network design and infrastructure are important for providing secure connectivity and effective facility operations. This essay analyses the suggested solutions and explanations, including the networking devices and the implementation of a star topology to guarantee the best connectivity and performance inside the Computer Centre.
The topology used in this network diagram is star topology as it allows for centralised management and control of the network. The router and switch as a central hub allows the network traffic to be monitored easier. Besides managing the network traffic, it also allows troubleshooting issues to be managed easier and implement changes or updates. Overall, star topology improves the network efficiency in this network diagram. In addition, star topology provides scalability which allows easy expansion and addition of devices to the network. As in the diagram above, each floor will have its own distribution switch and it can be added when needed. Hence, it is more efficient and convenient for future growth of the network infrastructures. New devices also can be connected to the central router without disturbing other networks. Thus, scalability allows the future network to be expanded in case the number of users keeps increasing year by year. Furthermore, in a star topology, if one link connecting a device to the central hub fails, the rest of the network will remain unaffected. However, the other devices that are connected to the router will remain uninterrupted. Each device maintains its connection to the hub independently, so the failure of one link does not disrupt the overall network.
In order to provide effective connection and operations, the LAN network design and infrastructure of the Computer Centre use a star topology. The main point of connection is the Central Switch, and connectivity with other networks is made possible through routers. Wireless Access Points give wireless connectivity throughout the Computer Centre, and Access Switches allow local network connectivity on each floor. With the assistance of critical services including Email, Student Information System (SMP), Staff Information System (SMSM), Financial System (SMKB), and ULearn platform, this network design assures seamless connectivity and effective data transmission. The star topology makes it possible to have a managed and centralised network infrastructure, which improves the Computer Center's overall speed and connection.
Communication media
The Computer Center's LAN network design and infrastructure are essential for ensuring seamless connectivity and effective operations inside the building. In order to ensure dependable data transmission and communication, this essay explores the suggested fixes and justifications, as well as the network devices and communication media.
The communication media that we used in this network diagram is fiber optic cable. To transfer data as light pulses, fiber optic cables use tiny glass or plastic fiber strands. They provide low latency, high bandwidth, and insulation against electromagnetic interference. High-speed internet connections and long-distance communication both frequently use fiber optic lines. This is because they can carry a huge amount of data over a long distance without any significant loss in signal quality which makes it the best for data centers. Besides that, fiber optic cables also can transmit data at very high speeds. Hence, it can improve overall network performance. Moreover, fiber optic cable has a very wide range of distance where it is suitable to use for network in university.
Next, it also has wireless connectivity, Throughout the buildings, wireless access points have been deployed in strategic locations. These WAPs provide wireless communication, which allows devices like tablets, smartphones, and laptops to get connected to the network without requiring actual Ethernet connections.
