Proposed Solution For UTeM Network Infrastructure
Figure 1.0
Network Topology: Star Topology
The network topology used in Figure 1.0 is star topology. In this star topology, all subnetworks are connected to the computer center router. All the subnetworks can be managed individually from the computer center which makes any troubleshooting easier. Star topology is also scalable, so any devices can be added to the network by connecting them to the central hub.
Other than that, only specific connections will be affected if any devices or cable fails in a star topology. The rest of the network will not be affected and continues to function normally. So this fault isolation will facilitate the troubleshooting process because the devices that cause the problem can be identified and replaced without affecting the entire network.
Besides, star topology can improve network performance and increases data transfer speed because it eliminates the need for the devices to share bandwidth. The security level can also be enhanced using this topology because it is easier to implement security measures like firewalls and access control lists at the central point when all devices are connected to a central hub. This centralization makes it easier to manage and update security policies and ensure consistent security across the network.
Communication Media: Fiber Optic
In this network infrastructure, we use fiber optic cable as communication media to connect from the computer center's router to all 10 subnetwork's routers because it can transmit large amounts of data at high speed over long distances without significant signal degradation. It also provides higher bandwidth compared to other copper cables.
Besides, fiber optic cables provide a high level of security in data transfer. They don't emit signals, therefore it's hard for would-be eavesdroppers to connect to the network and steal data. Furthermore, fiber optics give an extra layer of physical protection because it is challenging to tap them without significantly disrupting the network.
Furthermore, fiber optic cables are lighter and thinner compared to copper cables. These make them simpler to install, handle, and manage. Higher-density installations are possible since they may be packed together and take up less room in cable ducts.
Last but not least, fiber optic has a high potential for future growth. Fiber optics can sustain larger data speeds thanks to advancements in transmission technology as network demands rise. It is frequently simpler and more affordable to upgrade fiber optic infrastructure than to completely replace a copper-based network. The features and advantages that fiber optic provides make it suitable to be used in UTeM network infrastructure
Networking Devices: Router
For networking devices, we use the router. This is because routers can enable network segmentation by dividing a large network into smaller subnetworks. This will enhance the network performance. By enabling the creation of new subnets or networks without interfering with the existing infrastructure, routers also aid in network scalability.
Conversely, routers often include built-in security features, such as firewalls and access control lists (ACLs). With the help of these features, routers can examine and filter network traffic, guarding against malware, unauthorized access, and other security risks. Routers contribute to overall network security by implementing security policies at the network edge.
In addition, routers can be configured for redundancy and failover purposes. In the event of a router failure, backup pathways and automated failover can be provided by routers by implementing protocols like the Virtual Router Redundancy Protocol (VRRP). This increases network dependability and minimizes downtime. Another reason we use routers is that its straightforward to set up and manage because of their user-friendly interfaces that facilitate technicians to configure and manage the devices.
