After a thorough analysis of the selected organization it has been noticed that ICN
gateway has a large geographical area for the business operation which includes the Australia
and New Zealand in order to establish the business goals and objectives. As the objectives of
the organization has mentioned that it provides the services to the project by including the
local resources thus it is essential to interconnect several area with is a network for the
betterment of the organization services. The organization has now selected to open a new
branch in Sydney Australia for increasing the efficiency of business operation and enabling
communication with the other branch offices for sharing business information securely.
The proposed system offers to incorporate the areas into a single network by
providing LANs for each location of the organization where it is connected with the VPN and
to the internet in order to effectively transmit the information. Each network of the
organization is segregated into sub networks as well as the LANs of each area is sub divided

into VLANs for each department present in that branch. Thus, from this geographical
analysis it can be stated that the incorporation of the Cloud computing and virtualization has
a significant scope towards the success of the ICNgateway (Avram 2014).
2.2. Logical Diagram for Sydney Branch
The logical network diagram for the Sydney branch is created based on three layer
hierarchical model and for the design two ISP providers are used such that if the internet
service of one of the provider is down the other provider can be switched for the downtime of
the network is reduced. A firewall is used for securing the network from the external agents
and keep the servers secured. The servers are connected using a demilitarized switch for the
management of the access of the users. Two core and two distribution level switches are used
for balancing the load of the network and increasing redundancy. Since the building is of 8
floors and each of the floor have a lobby area 8 access level switches are used and for the
lobby area a wireless access point is installed in the network. The wireless access point
allows the users of the floor to connect their wireless device with the network and increases
their performance and efficiency by easily accessing or sharing information with each other.
