Summary
The objective of this report is about representing the geographical expanse of the overall
network of APIC or Asia Pacific International College as also detailing logical and physical
design of their recently established Sydney branch while also talking about computing and
associated virtualization techniques. After illustrating the global spread of APIC’s internal
network, short notes are given about the backbone devices necessary for establishing the
internetwork of the company’s various branches. After that, the logical and physical design of
the network of Sydney branch is elaborated. This is achieved with the three-layer hierarchical
network diagram drawn in cisco packet tracer and the physical network diagram in Visio.
Thereafter the network requirements are mentioned including IP addresses, the allocation
method and subnet calculation in the form of a table. Then, after suggesting the appropriate
cloud services for APIC and virtualization techniques, dynamic scaling functionality is
discussed after which the report ends with observations in concluding notes.

Introduction
This report assesses the geographical spread of the interconnect of networks
belonging to the different branches of Asia Pacific International College and after detailing
the logical and physical designs for the recently set up Sydney branch, discusses how cloud
services are being utilized by the branch. The report begins by illustrating the global coverage
of APIC’s overall network and discusses about the backbone devices required for setting up
the internetwork of the different branches of the company. Then, the logical and physical
design of the network of Sydney branch are provided and described. Cisco Packet tracer is
used to draw the three-layer hierarchical network diagram while the physical network
diagram in drawn with Visio. After which the network requirements are given and IP
addresses, the allocation method as well as subnet calculation is mentioned using a table.
Thereafter, appropriate cloud services for APIC is suggested and virtualization techniques
discussed. After talking about the use of dynamic scaling functionality, the report ends with
concluding notes.

Network Study
Scope of Overall Network
Figure 1: Geographical scope of APIC’s network
This diagram shows the intercontinental coverage of APIC’s overall network. The
different branches of the global interconnect are situated across the United States in North
America, the countries belonging to the European union in Europe as also cities of Perth,
Canberra, Sydney and in the island of Tasmania in Australia. Each and every branch is
interconnected with the rest of the branches which includes the new branch at Sydney. The

5APIC BRANCH NETWORK
internetwork has only been possible with the help of GAN (Global Area Network)
networking topology (Sridevi 2018). Additionally, internet connections for every branch is
ensured by directly connecting them to ISPs.
Backbone Devices
Routers and switches play a big role in setting up networks. The routers dictate the
path or route through which network communication should take place while switches are
used for distribution of network connections and providing access to computers, servers and
other endpoint devices (Feldmann et al. 2016). However, it is also important to have firewalls
installed as the threats from information security risks has grown at an alarming rate over the
last decade. Corporate firewalls can be very effective for the network of APIC and can help
address most of the security concerns.
Segmentation of Networks
Every branch of APIC divides their primary network into subnets to more easily
provide efficient network access to each of the eight floors. This segmentation of the network
can either be done directly or through VLANs (Xu and Xu 2016). Segmentation can help
improve performance by reducing traffic in a single network. If faults or security risks arise
in a part of the network, the particular segment can be isolated to limit the spread of the risk.
VLANs can be created for controlling network access by different users.
Usefulness
The global interconnect of APIC can be used to enable easier and more effective
mode of network communications among the different branches. The network of APIC can
be shared with affiliated institutes. It can also enable students to more actively make use of
the digital media.

Logical Network Design
Figure 2: Three layer hierarchical network design
This diagram gives the logical representation of how a branch obtains internet from
the Internet Service providers or ISPs and make use of the different routers and switches to
provide connections to the computers, laptops and servers (Quach, Thaichon and
Jebarajakirthy 2016). Also, the diagram shows how cloud services are accessed by the branch
through their main router. The internet, ISP the main router and the cloud service together
forms the core. The multi-layered switch receives the connection from the router and
distributes it to the respective switches of the eight floors. These switches located in every
floor are tasked with providing network access to the individual devices installed in the
building (Lin et al. 2016). This includes the wireless access point, the four servers, computers
and laptops.

In this figure the physical layout of the network at Sydney branch of APIC is
described. The router of the branch, the multilevel switch, servers, computers, laptops and the
wireless access point is present in the bottom most floor along with the floor specific switch.
The rest of the floors house the computers, laptops and their respective switch.

Cloud Services and Virtualization
The two suitable organizations identified for serving the purposes of Asia Pacific
International College are Amazon and IBM. These two are organizations are the business
leaders in the field of cloud computing. The solution offered by them are Amazon Web
Services (AWS) and IBM Blue Cloud.
The college APIC mainly requires cloud services for web hosting and email-based
services. Although IBM Blue Cloud, capable of serving both as IaaS (Infrastructure as a
Service) and PaaS (Platform as a Service) can provide all the services, AWS from Amazon is
built specifically for web hosting and emailing services and also comes much cheaper than
IBM Blue Cloud which is more advisable for large enterprises (Demydov et al. 2015). Hence
it is advisable for APIC to use AWS.
Virtualization
The cloud specific virtualization techniques that help APIC in web hosting and
facilitating emailing services through AWS are network virtualization, server virtualization,
storage virtualization and application virtualization (Dalton et al. 2018). AWS being an IaaS
provides limited network resources for enabling web and emailing services by itself
(Villamizar et al. 2016). The servers operated by Amazon also help in maintaining uptime of
these services. The S3 storage services of AWS ensure that user data from web portal or mail
clients are successfully maintained and secured. The application streaming features enable
streaming services for APIC’s branches.
Dynamic Scaling
The dynamic scaling functionality of AWS is also called Auto Scaling Sides, M.,
(Bremler-Barr and Rosensweig 2015). Auto Scaling dictates how resource usage can be
optimized based on the rules mentioned in AWS scaling policy (Jannapureddy et al. 2019).

10APIC BRANCH NETWORK
There are three ways to optimize resource usage which are availability, cost of use as well as
a balance of availability and cost.
The exams of Asia Pacific International College can be scheduled and run using auto
scaling. Depending on the time and location, users accessing the exam session can vary
across all the branches. Auto Scaling with the correct scaling policy can dynamically adjust
the resources being made available for the sessions thus helping APIC save on costs.
Conclusion
To conclude the report successfully assesses the geographical spread of the
interconnect of networks belonging to the different branches of Asia Pacific International
College and after detailing the logical and physical designs for the recently set up Sydney
branch, discusses how cloud services are being utilized by the branch. The report clearly
illustrates the global coverage of APIC’s overall network and discusses about the backbone
devices required for setting up the internetwork of the different branches of the company.
Then, the logical and physical design of the network of Sydney branch get provided and
described. Cisco Packet tracer is used to draw the three-layer hierarchical network diagram
while the physical network diagram in drawn with Visio. After which the network
requirements are given and IP addresses, the allocation method as well as subnet calculation
is mentioned using a table. Thereafter, appropriate cloud services for APIC is suggested and
virtualization techniques discussed. After talking about the use of dynamic scaling
