Network Design for Recommended Network_1
Executive SummaryNetworking in each and every organization either small or larger or even old or new in market willalways remain to be a very important area and understanding the design that a network will need toundergo then one understands the type of network topology to be set by the company. Many organizationsin the economy have seen the urge to have a need to upgrade their networks which in deed is helping inreducing the paper work as much as possible. This has made the centralization of information in one placeto be effective and hence making communication easy.Application of the topology will describe how good the design will look like, the topology will differ inthe manner how the IT components, Circuit (cabling is done), Networking cost in terms of the proposedbudget, how extensive it can especially if we consider how compatible it will be with other networkcomponents expanded in the future.5Star Software Development Company currently has a poorly designed network located in three of itsbuildings. That is, software development building, technical building and administrative buildingrespectively. Each building has its own server located in one of each building’s room. All these LAN areinterconnected together using a router. This network does not allow employees to log into it using theirlaptops or iPads. This therefore means that the entire layout of this network is not scalable and does notallow connectivity of extra computers other than those that are already connected. The current network isless secured, not easy to manage or troubleshoot and the fact that it does not have a defined structuremakes it slow in performance. Computers are connected to the network via Ethernet cables and there is noavailability of Wireless 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 a router failurethe 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 network design that support allthese ought to be put into place [ CITATION Col12 \l 1033 ]. The company therefore should implement athree layered hierarchical networking model with its all of its servers hosted on cloud. The three-layeredarchitecture will enhance network performance as well as make it easy to manage and troubleshoot. Thisnetwork model will also enhance scalability as it makes it possible to extend the network on each of thethree layers of the model (i.e Access, Distribution and Core Layers) [ CITATION CIS14 \l 1033 ]..Cloudservers also will make the network more reliable and available to all the employees in the company. To

accommodate more users especially employees with ipads and laptops a wireless access point would beappropriate this will enhance network accessibility thus improving employee’s performance. Softwaresuch as Networking Operating System will enable the overall network administrator to monitor andcontrol network resources thus making it manageable. Also the company should install Anti-Virussoftware to ensure that they avoid external malicious attacks that could be targeted on their network.From all these issues, it is clear that a client-server network model will be appropriate to attain 5StarCompany Business goals laid.Network Design for Recommended Network(s)This is the evaluation, understanding and the scope of the network that need to be implemented by 5StarCompany [ CITATION Tec17 \l 1033 ]. The network consists of various components ranging from networkcabling (circuits), hardware components and software components. These components are interconnectedto form a network layout or topology that represents how the network design looks like and operates. Thecomponents of the IT infrastructures that make up the ICT in the technology world such as the servers egthe DHCP, web servers, DNC, etc., hardware components such as the client machine, scanners, printers,laptops etc. and lastly but not leat is the topology clearly stating the layout or the arrangement of all thedevices connected over the network [ CITATION Cis13 \l 1033 ]. Circuit with reference to cabling willclearly states what type of topology will be applied.Network CircuitsThis consists of transmission media that allow computers to communicate with each other across thenetwork. The main media being the network cables that are required for the proposed network include:Fiber cable This will act as a transmission media and connects networking devices for faster transmission across thenetwork. This transmission cable will connect core components to distribution components and end usercomponents in the network. With fiber cable, it will be possible for the company to connect with theirbranch located at 200KM. Fiber cable is fault tolerant, this makes it more reliable. The cable alsoenhances high speed data transfer thus making the communication between all departments at 5StarCompany faster and more productive.Ethernet cat5 cable This cable shall be used to connect access layer devices to the whole 5Star Company LANs in eachbuilding. The cables connect personal computers to extension switches in the network thus makingcommunication possible.

RJ 45 PlugsThis will be used for network cable termination for the proposed network design. RJ 45 will be usedtogether with the Ethernet cat5 cable and they are the most important part of the network circuit.Hardware ComponentsNetwork SwitchesThis provides interconnection of other network devices within a network [ CITATION Bra171 \l 1033 ].The types of switches that 5Star Company should go for based on future extensibility factor are modularswitches. This kind of switch will enhance flexibility and future extensibility for 5Star Company. Theseswitches support modular line cards that allow addition of ports on the switch in the case of scaling thenetwork.RouterThis device will allow connection of 5Star networks and extend to internet accessibility. The router willenhance communications between the three LAN networks for 5Star Company.Wireless Access Point (WAP)WAP is a hardware component that will need to be put in to place so that we do not rely only on thecabling network but we also have a chance to have a wireless network where we can even use our phonesto connect over the network. This will ensure that additional or other clients or workstations areconnected to 5Star network wirelessly. The device will broadcast digital signals across 5Star Company ata given range.Server ComponentsThese include; DNS server, mail server, Web server, file server, DHCP server, Database server and printserver. The devices will provide important functionalities in the network design.Workstations devices These are employee’s personal computers, office IP phones among other devices connected to the 5StarNetwork.Software ComponentsThese include operating systems, Network Operating System (NOS) which are executed other networkfor sharing resources across the 5Star Network. Another software is Anti-Virus software to enable the company overcome malicious attacks from externalattackers.The network to be designed will therefore rely on the named components in order for the design to besuccessful [ CITATION Mba12 \l 1033 ].
