NIT1104: Computer Network Design for Victoria University

This project report details the design of a Local Area Network (LAN) for Victoria University's five-story building. The network is designed using Cisco Packet Tracer and divided into subnets with specific IP address assignments for different departments and labs. The report includes a site map, a list of network inventories (devices, cables, and accessories), and a comprehensive IP network addressing plan using variable-length subnet masks. Detailed configuration commands for routers and switches are provided, along with screenshots of the simulated network. The project aims to enhance the university's productivity and facilitate communication between departments by providing a robust and efficient network infrastructure. The bibliography provides a list of references used for the project.

1. Introduction
The network is design for Victoria University and detailed design of the Ethernet for its
five story building is given in the report. The LAN is sub divided into different parts and the
prototype of the network is deigned in cisco packet traces and attached with the report. Different
subnet and IP address is used for different parts of the network according to the requirement of
the university. The computers connected in the office are assigned same IP address and the Lab
network is designed with different IP address.
The design of the network is proposed detailed function of the network is shown in the
report that would help to improve the productivity of the university and help to communicate
with the departments easily. A sitemap is created for the network for demonstration of the
location of the device that is installed in the network. The list of the network address that is used
for the configuration of the network devices are given in the network. The network is configured
and the configuration are given in the configuration document and the screen shot of the
simulation are attached for increasing the efficiency of the network.

4. IP network addressing plan
Variable length subnet mask is used for the preparation of the addressing plan and some
extra IP address are reserved for each of the subnets for supporting the growth of the university
network solution.
Addressing plan for the Office and Computer LAB
