1 Introduction
This project aims to design a network solution for Advanced IT training company that
network solution must be satisfied the requirement of Advanced IT training company. This
company is founded in 1998 which is used to provide the consultation and training services
for information technology students. It has many branches and headquartered in Los Angeles,
USA and subsidiaries in various countries Australia, India and Canada. The Advanced IT
training company needs to provides the high quality and advanced training for Australia
people and company head office is placed in Sydney. It has various branches which are
presented in Adelaide, Brisbane and Melbourne. This company needs to implement the
network to support the potential growth over the next five years. So, this company decided to
hear the user that is network solution provider. The network solution provider is used to
create the layout the network with an expectation of 30% growth of current IP requirements.
The Sydney head office has two major building like building A and Building B which are 5
km apart from each other. So, this company requested to set up the leased line to connecting
the two building with security measurements. The Sydney head office has the Admissions,
finance, marketing and IT support department. The Melbourne Branch distance across a
single area which is 50 m x 30 m and it has the Admissions, finance, marketing and IT
support department. The Brisbane branch distances across an area of 25 m x25m and it has
the Admissions, finance, marketing and IT support department. The Adelaide Branch
distances across an area 45 m X 30 m with single storied building and it has the Admissions,
finance and IT support department. This company requested at least one separate printer for
each department in each branch and also needs separate server reserved. The head offices
needs the access to all the devices over the network to both configure and monitor as
necessary using a secure network connection. It also needs the implementation of security
policies to control the IP traffic flow within the network to the internet. So, user needs to
design the network infrastructure for AITT Company and specify the details about the
network technologies and devices to be used and implement the network simulation using the
GNS3. The network infrastructure will be done. The specification of network devices and
technologies are will be done.
