In this project we will be providing a network design to Malcom Technologies. Malcom Technologies is an upcoming business enterprises that is a main distributor of wheel-bearings. This is not only attributed its hard working marketing and sales team, but also quality services they offer their customers. Due to increased growth, Malcom Technologies management has decided to redesign its network infrastructure in support of its business activities.
Non-functional requirement refers to those requirements that will specify the criteria that is used to provide a judgement of operations of a system. For our network project design, the following are the non-functional requirements:
Scalability: our designed network should be scalable in a manner that in case of a need of expansion, the expansion should be done without any form of interruptions to the current network structure.
Performance: the performance of our designed network should have a high work performance without laxity in the network flow.
Reliability: the designed network will be reliable and minimal downtimes will be experienced.
Functional requirements are the requirements that defines what the system should perform. For instance, in our network design, the designed network should be able to do the following as described by the administration:
Engineering and sales department should have access to print services
Finance, Human Resource and Admin departments should have access to all network infrastructure resources.
Sales and engineering should not access finance department at no single time.

Our network designed above can be handed over to Malcom Technologies. The design was mainly human centred design where we did the design on the basis of human use. It is kept simple and not complicated nor with a lot of jargon.
The configurations in our devices are kept simple and easy to understand. Additionally, comments are included to enable whoever is studying the network should not find it difficult. The devices are configured in Netsim Boson simulation software. Configured devices include the following together with their configurations:
Router- router is configured with Router-On-a-stick technology to enable inter-vlan communication.
For our server, we use windows server 2012R to host our DHCP and DNS server services. We opt for windows server 2012 R version as it is not complicated and supports the latest technology. This technology more so, supports virtual interfaces to allow more devices to appear as if they are directly connected to the router.
The switches are configured with five vlans. Each vlan represent a department. Vlans are virtual LANs that support segmentation of a network in logical manner.
Wireless access points in our topology are used to support wireless handheld computing devices for them to access the internet.
In our network design, we assume our ISP provided address is class B address that we use for IP addressing. We therefore subnet into five subnets each subnet hosting a maximum of 254 devices.
