COIT 11238 - Network Design Proposal_1
Executive Summary5Star Software Development Company currently has a poorly designed network located in threeof its buildings. That is, software development building, technical building and administrativebuilding respectively. Each building has its own server located in one of each building’s room.All these LAN are interconnected together using a router. This network does not allowemployees to log into it using their laptops or iPads. This therefore means that the entire layoutof this network is not scalable and does not allow connectivity of extra computers other thanthose that are already connected. The current network is less secured, not easy to manage ortroubleshoot and the fact that it does not have a defined structure makes it slow in performance.Computers are connected to the network via Ethernet cables and there is no availability ofWireless Access Point to accommodate extra connections wirelessly. The central point ofconnectivity where all the LANs are interconnected is vulnerable to failure and in case of arouter failure the whole network will be paralyzed thus making it less reliable. To achieve the main business goals for this company, which include, scalability, availability,security, improved performance, reliability , accessibility and availability, a better networkdesign that support all these ought to be put into place [ CITATION Col12 \l 1033 ]. The companytherefore should implement a three layered hierarchical networking model with its all of itsservers hosted on cloud. The three-layered architecture will enhance network performance aswell as make it easy to manage and troubleshoot. This network model will also enhancescalability as it makes it possible to extend the network on each of the three layers of the model(i.e Access, Distribution and Core Layers) [ CITATION CIS14 \l 1033 ]..Cloud servers also will makethe network more reliable and available to all the employees in the company. To accommodatemore users especially employees with ipads and laptops a wireless access point would beappropriate this will enhance network accessibility thus improving employee’s performance.Software such as Networking Operating System will enable the overall network administrator tomonitor and control network resources thus making it manageable. Also the company shouldinstall Anti-Virus software to ensure that they avoid external malicious attacks that could betargeted on their network. From all these issues, it is clear that a client-server network model willbe appropriate to attain 5Star Company Business goals laid.

Network Design for Recommended Network(s)This is the evaluation, understanding and the scope of the network that need to be implementedby 5Star Company [ CITATION Tec17 \l 1033 ]. The network consists of various componentsranging from network cabling (circuits), hardware components and software components. Thesecomponents are interconnected to form a network layout or topology that represents how thenetwork design looks like and operates.Network CircuitsThis consists of transmission media that allow computers to communicate with each other acrossthe network. The main media being the network cables that are required for the proposednetwork include:Fiber cable This will act as a transmission media and connects networking devices for faster transmissionacross the network. This transmission cable will connect core components to distributioncomponents and end user components in the network.Ethernet cat5 cable This cable shall be used to connect access layer devices to the whole 5Star Company LANs ineach building.RJ 45 PlugsThis will be used for network cable termination for the proposed network design.Hardware ComponentsNetwork SwitchesThis provides interconnection of other network devices within a network [ CITATION Bra171 \l1033 ]. The types of switches that 5Star Company should go for based on future extensibilityfactor are modular switches. This kind of switch will enhance flexibility and future extensibilityfor 5Star Company. These switches support modular line cards that allow addition of ports on theswitch in the case of scaling the network.
