IntroductionNetworking is the process of interconnecting computing devices with the aim of sharing ofresources and information according to Mitchell [ CITATION Bra171 \l 1033 ]. There are variousnetworking designs implemented in different organizations. This proposal suggests a networkingdesign both with dedicated server and cloud design for iTech Company.Objective of the ReportThe main objectives [ CITATION Col12 \l 1033 ]to be achieved from this network include:Scalability/Extensibility – This is the addition of more networking devices or extension of thenetwork without have to carry the installation process afresh.Easy troubleshooting and management – This is the ability to handle networking problemsarising as well as proper management of the network by iTech.Security of iTech operations – The design should ensure that operations at iTech are properlycarried out and in a more secured manner across the network.A thorough and detailed analysis of the Network infrastructure components need, design ofthree-layered hierarchical model, use of dedicated server design, cloud based design and DataCenter Building network design simulation of iTech is discusses in this proposal. This report alsosuggests various recommendations points on the networking design to be implemented. Thedocument also gives a conclusion of the whole reportBackground iTech Company majors in software development and is located between three adjacent five-storybuildings in an office park. The company has 900-workstations network distributed across eachbuildings, each having approximately 300 workstations. The three buildings of ITech Companyhave similar LAN. The DCB for this organization is located on the second floor of one of thefive-story buildings. Here, servers such as mail server, web server, file server, DNS and DHCPserver are hosted. Its domain name is www.iTech.org.au. This organization’s network design isnot well designed hence call for replacement.
IT Infrastructure ComponentsSome of the IT infrastructure components needed for the proposed design are:Computer Networks Hardware ComponentsThis consists of:a)Network SwitchesThis provides interconnection of other network devices within a network [ CITATION Bra171 \l1033 ]. The types of switches that iTech Company should go for based on future extensibilityfactor are modular switches. This kind of switch will enhance flexibility and future extensibilityfor iTech Company. These switches support modular line cards that allow addition of ports onthe switch in the case of scaling the network.b)RouterThis device will allow connection of iTech networks and extend to internet accessibility. Therouter will enhance communications between the three LAN networks for iTech Company.c)Wireless Access Point (WAP)This will ensure that additional or other clients or workstations are connected to iTech networkwirelessly. The device will broadcast digital signals across iTech Company at a given range.d)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.e)Server/Storage ComponentsThese include; DNS server, mail server, Web server, file server, DHCP server, Database serverand print server. The devices will provide important functionalities in the network design.f)Ethernet cable This cable shall be used to connect access layer devices to the whole iTech LANs in eachbuilding.g)Workstations devices These are employee’s personal computers, office IP phones among other devices connected tothe iTech Network.Software ComponentsThese include operating systems, Network Operating System (NOS) which are executed othernetwork for sharing resources across the iTech Network. The network to be designed will therefore rely on the named components in order for the designto be successful [ CITATION Mba12 \l 1033 ].
Three-Layer Hierarchical ModelThis model breaks down network design into three layers. The layers perform variousdifferentiated functions thus simplifying the network design [ CITATION CIS14 \l 1033 ]. Thehierarchical model layers are; Access layer – connect end users to the network.Distribution layer –connects access layer devices to distribution servicesCore layers –connects distribution layers to iTech LAN.The layers can be shown below.iTech Company should therefore implement this model when designing their new networkconsidering that the size of the organization. Separating the network into three layers will make iteasier for iTech Company to manage their network.Current networkThe current network design is not well organized. The Flat network model in use currently treatsall the networks and their components to be on the same level. This makes it harder to manageiTech network and also conduct the administrative operations effectively. The current network atiTech Company cannot be extended effectively without affecting the whole network operations.Also having similar LAN in each building in both design and operations, makes it difficult totrouble shoot. The network is also poorly secured and a slight mistake may paralyze the wholenetwork.
Future iTech IT Infrastructure The intended future design is based on three-layer hierarchical design model. This network willhighlight each component represented in each layer of the iTech Network. With this design thenetwork will be more simplified, flexible, scalable, and easy to troubleshoot and manage. Thismeans that the network at ITech Company will be more clear and visible [ CITATION Cis13 \l1033 ].
