Infrastructure of UTeM's Network

Network Devices
The networking device used in this infrastructure is a high-performance router, positioned at the core of the network. It is responsible to manage the primary traffic flow and unifying the several subnetworks (FKP, FKM, FKEKK, FKE, FTMK, Post Graduate Centre, Canselory office, Registrar office, Library, and Sports Centre) on UTeM’s main campus. Routers are in charge of facilitating data transmission across linked networks. A router can forward data to the right network in a manner similar to a switch. It uses the most efficient channel to forward packets to their destination, which may be miles away.
Topology
Star topology is chosen to be the topology of UTeM’s main campus network infrastructure. It is known as a type of network topology in which every device in the network is individually connected to a central node, which is a switch or hub. Each device has a dedicated point-to-point link only to a central controller (or hub). The star topology minimises the impact of a transmission line failure by connecting each host to the hub individually. Each host may therefore communicate with all others by sending and receiving data from the hub. The failure of a transmission line connecting any host to the hub isolates that host from all others, while the remainder of the network remains unaffected. The significant benefit of this topology is only one link and one input/output (I/O) port is required per device. This port serves as the interface through which the device sends and receives data to and from the network. This simplifies the network connections and reduces complexity as it allows for easier troubleshooting, as there is a clear and direct connection between each device and the central device. Next, in a star topology, if one link fails, only that link is affected. This is to maintain network robustness. Other devices in the network remain unaffected and can continue to communicate normally. In addition, the star network design facilitates fault identification and isolation, allowing for the rapid discovery and resolution of network issues. When a device or connection fails, the impact is limited to that single element, ensuring that other devices linked to the central hub or switch continue to communicate. These advantages contribute to a reliable and efficient network infrastructure.
For the communication media, fiber optic cable which is made of thin strands of glass fibres is used to transmit data from the Computer Center to all of the other subnetworks in the form of light pulses. Compared to other communication media, fiber optic cable can transmit a larger amount of data at a higher rate as it has a greater bandwidth capacity permitting high-speed data transfer and real-time communication. Besides, the users of the network would not encounter any significant delays with their connection as the light signals in this cable experience minimal attenuation which have resulted in a more reliable communication even for long-distance communication without significant signal degradation. A high level of security is provided by fiber optic cable for data transmission due to no emission of electromagnetic signals that can be easily intercepted which makes it highly difficult to be eavesdropped. Apart from that, it is more reliable and requires less maintenance compared to other communication media as they are less susceptible to environmental factors such as temperature changes, moisture and corrosion. Lastly, fiber optic technology is constantly developing and evolving. Therefore, it is the most practical option to invest in fiber optic infrastructure where organisations can future-proof their networks and accommodate the increasing demands for higher bandwidth along with faster rates of data transfer without having to rebuild the entire cable infrastructure because enhancement can be made seamlessly by upgrading the equipment as well as utilizing advanced transmission technologies.
