3. Executive Summary
Use of modern computing technology is getting more sophisticated. So companies
and customers dream about new and high expectations. That changes the working of old
file system. Advancement of technology allows impact on company and customers. There
are number of companies in market and there are different types of completion between
them. Rapid access to critical information and the ability to get quick result will help
company to grow up in the market. This also helps company a competitive advantage in
different fields like accounting and service environment.
This project is about Globex that offers various types of tools and agriculture services
to clients and farmers. Globex requires a cloud based system that helps their employees to
access data from any location using sensor and devices. Now Globex has various branches
in different areas. So according to employees and customers of Globex, they waste time to
visit each other. So the organization requires a system based on cloud.
Network design involves an upgrade to existing network. The design must consist of
mitigation of risk and less risk of data loss. The old system of Globex can support many
users at a time and the users are vulnerable to attacks and the data is not secure.
4. Project Goals
The Customers need greater admittance and more flexibility and with the help of new
cloud system, Globex can offer better services to their customers. Globex is aware of new
technologies and they know that customer need more services. Internet technology
maximizes competition between various companies. So according to Globex, their Project
goals will be:
 Remote access to accounts: remote terminal at customer site connect to servers utilising
internet that enable clients to make enquiries online without visiting offices.
 Anytime access: by using new network, the employees of the company can access data
or questions from any location.
 As data is centralized, so updates will be easily available which minimizes wastage of
time.

5.3. Routing and Switching Protocols
It is main part of project and following are various areas that are to be considered:
In our project we are going to use a system that is based on cloud (Hasan, Al-Rizzo & Al-
Turjman, 2017). The four routers are connected using OSPF that is the popular protocols of
routing that are based on standards. The advantage of OSPF is that if any changes happens
in the routers then it can automatically adapt to the changes. There are two types of routing
protocols. These include classless routing protocols and classful routing protocols. All the
devices or computers are connected to cloud system using internet.

5.4. Security
Networking field in computer involves securing a network. It is handled by a network
administrator and a system administrator (Fisch, White & Pooch, 2017). They help to save
network from unauthorized access and also ensure that employees have their access to
network.
Common network security threats are
 Spyware
 Adware
 Virus
 Worms
 Hacker attack
 Identity theft
 Denial of services attack
Network security refers to safeguard data from outer attack so that data is not
misused. Security depends on various layers of protection that include security in both
hardware and software (Acemoglu, Malekian & Ozdaglar, 2016). Different security
measures that can be used are:
Firewall: Firewall help to secure network against attacks on application layer including
browser. There are different types of firewall available that help to secure application
layer.
Cisco firewall: CISCO firewall is a good solution that is certifies by EAL4.
 It safeguards network resources by using routing capabilities that provides threat
mitigation of worms and viruses
 These devices use less power and reduce power consumption.
 These firewall offer different options and can be used in WAN, LAN, VLAN. They
also provide policy based access control.
A key feature of Cisco includes:
 Integrated ports
 High speed WAN interface
 DSP slots
 Internal service module
Benefits of using Cisco
 Cisco provides increased level of service integration with voice, video and security.
 They provide greater efficiency and are cost saving

 Larger memory of devices helps to support new capabilities in system.
 It enables new operational models that allow reducing capital expenditure.
 Devices are designed to address customer business requirements.
Architectural benefits and features
 Cisco provide different type of slots to add connectivity that can be used in different
branch offices
 Cisco series are powered by high speed processors to support high speed network
 USB ports allow connectivity of different devices that does not have serial ports.
VPN
A virtual private network is a network that is created utilising wires of public usually
the internet in order to connect users those are remote or regional offices to a private or
internet network of a company (Cho et al., 2019). Larger corporation like Globex use VPN
technology to provide remote access to clients and employees. VPN connects different
WAN and creates a single network. VPN uses authentication to gain access to network
VPN can be used in order to access region websites those are restricted; protect activity of
browsing from snooping on public Wi-Fi.
5.5. Virtual LANs
VLAN allow network administrator to group host when they are not connected to same
network As VLAN can be configured through network software so it helps to simplify
network design and it will be easy to deploy network (Abdullah, 2016). As Globex has
three offices that are located at Albury, Wagga Wagga and Griffith. So they need a Virtual
LAN. Without using a Virtual LAN they require different network management team at
various offices that maximizes number of employees and labour. VLAN also offers better
security and minimizes need of hardware. Griffith has a VLAN which are utilised by their
main department.

5.6. Wireless Networks
Wireless network permits devices to connect with network, for example mobile
devices connected to wifi. In many cases it is seen that wifi minimizes the security and
maximizes risk of data breaching (Sarkar, Basavaraju & Puttamadappa, 2016). Mobile
devices or smart devices are not secured. So there are number of risks in using wireless
networks. So Globex has not installed wireless network.
5.7. QoS Design
QoS or Quality of Service prioritizes traffic in a network so that traffic with high
priority can pass first through network. Globex want to use QoS service at their Griffith
office (Ahson & Ilyas, 2018). It makes sure that efficiency of network that ensures that
critical application has always good assets and help to minimize cost and upgrade
experience of user.
5.8. Network Management
Network management is the procedure of administrating computer assets so that
they are used efficiently. It includes fault analysis, quality of service, performance
management and many more. Objectives of network management include network
availability and security. Network management is required in traffic management and
traffic measurement. It also helps to detect violations of network security.
6. Physical Design
6.1. Network Topology
The network structure of Globex is easy and simple to establish. They use LAN
technology to connect their office devices and uses WAN to connect with cloud (Tedik
Basaran et al., 2019). So they use mesh topology in network. Mesh technology is easy to
setup and is less costly as compared to other technologies.
6.2. LAN technologies
LAN is used in order to connect computer or devices in an area. Globex uses LAN at
their three offices (Gaj et al., 2016). All of their devices in offices like printers and
computers are connected using LAN.
4622157372739179733.docx 8 of 16

6.3. WAN technologies
Globex has three offices that are connected to cloud server using WAN. A Wide Area
Network is a geographically private network those are distributed that connects more than
one local area networks (Mermer & Zeydan, 2017). In a business, a WAN includes
connections to a headquarters, branch offices, and cloud services of a Company.
