ITNE1001 Project: Designing a Network for Silver Industries

This project details the network design for Silver Industries, a mechanical company. The design encompasses the allocation of network devices, including routers and switches, along with their corresponding IP addresses and subnet masks. A comprehensive host list, detailing the number of devices per department (Reception, IT, Marketing, Manufacturing, Accounting, Customer Service, Quality Check, Store Room, Staff Room, and CEO's Office), is provided. The project utilizes Variable Length Subnet Masking (VLSM) to optimize IP address allocation. The document includes detailed network tables for routers and switches, specifying IP addresses and subnet masks. End device configurations, including IP addresses and subnet masks, are also outlined. The project also covers router and switch configurations, ensuring seamless communication within the network. The project focuses on creating an efficient and scalable network infrastructure for Silver Industries.

Network design

 The below diagram showcase the network devices and the connection which was
proposed for the silver industry.

Background
 Sliver Industries is a Mechanical company for which we are going to design the
network. For this whole design of network we are going to plan how many devices
does the company is in need of, the IP addresses of every device and the subnets for
the network. At last we need to decide the type of cable to be used for the network
connection by looking at the cost of designing the whole network structure.

Required host list

End devices
 Every end devices is comprised with an IP address and default gateway. The default
gateway is the IP address of the respective router.

Router configuration
 Routers are also configured with different networks addresses.

VLSM
 Variable Length Subnet Mask, abbreviated as VLSM, is a means to specify a different
subnet mask for the same network number on different subnets. With VLSM, a
network administrator can use a long mask on networks with few hosts and a short
mask on subnets with many hosts.
