Introduction
Advanced Medicos Limited (AML) is an organization which sells the health products digitally.
Their system is mainly hardware-based through which they provide health services to the
customers. Now Advance Medicos Limited wants to expand their business online so they can
sell their products through web application so all the customers can get the benefit of it and they
don’t need to buy the hardware system necessarily. All the customers want to buy an expert
system and so the feedback is taken from the customers and average customers are saying that
the current network is too old and this system needs to get replaced or redesigned.
Purpose
If the current network of the AML company will be redesigned using new technologies, then this
company will have a wide range for future growth and this network will give a boost to the
company sales performance and a strong customer relationship. The customer is the key
elements for helping in the growth of the company. It will increase communication between
different department network users (Wong, et al., 2015).
Background Information
The Advance Medicos Limited company is a digital health care company which provides users
their system for health care products. These products are basically on the hardware system which
is a company providing to its customers. So the company wants to deploy their online web
application so the customers can interact online without buying the offline system. The existing
system has 200 employees and four departments, Other provided details are:
Department User Workstations, Printers
Software Development 70, 10
Production 5, 2
Marketing 10, 4
Administration 5, 2
The company network has user workstations and the attached devices for every department, the
number is mentioned above. There are two building A and B of this company. Both buildings are
separated with a distance of 20 meters. The production and Software development department is
settled in building A and both remaining departments are in building B. The Company server
farm is suited to building B.

Scope for a new system
The new network which is going to be built in to improve the existing network. The current
scenario of the network is providing many services to the company but if there is a possibility to
add some more factors to advance the network like remote access, wireless communication,
advanced security, application of Machine learning, Artificial Intelligence Implementation, etc.
then this network can meet the modern standards for networking and the operations will help in
growing the business and customers.

Analysis of User Requirements
Technical Goals
There are some technical goals which are expected to achieve in the redesigned network by
comparing to an existing network:
 As the business is expanding the requirements of employees are also increasing so the
network should be compatible to address that much users. AML’s existing network does
not have sufficient space to manage the growth of the employees. So the new system will
have the capacity to manage the employee count for at least the next five years.
 Security for a company network is a very sensitive topic as if someone tries to breach the
network security, he can access all the confidential data of the company. In the
redesigned system, the application of machine learning and Artificial Intelligence will
help to maintain the security concern more powerful (Aleshin, et al., 2015).
 The company has four building at one place so the current network is providing the Local
Area Connectivity (LAN) but with the expansion of the business the company is
expanding the branches to another place so the redesigned network should provide the
connectivity among all the offices through Wide Area Network (WAN), this will make
the company network more strong.
 The redundant network ensures availability of network but the existing network is getting
too old and it used to face downtime while connection, so the new network will support
redundancy so it will recover this issue and devices can connect anytime.
Business Goals
 A company has various type of confidential data like employee data, banking data and
this data has to be secured. The existing network is highly vulnerable and this causes
many types of risk on the data of the system. If the network is more secure than the
business can grow without any risk.
 Operations are based on communication between the company’s employees. Various
types of data are being transmitted among different departments and users. This old
network is not capable for the wireless connection so the new network will be redesigned
using new technologies like BYOD (Bring your own device) and work from home, which
will help in making the network smarter (Saravanakumar, et al., 2015).
 Advanced Medicos Limited has many assets like medical information, patient’s data,
doctor’s data, and all these data have to be secured over the company network. The
redesigned network will have more security to prevent the data from malicious activities.

Description and Analysis of Current Network Setup
Data Transmission Media
Figure 1: Data Transmission Media, Cable Design
This figure is of cable designing for Advance Medicos Limited. This diagram shows that there
are many cables of multiple varieties are used in this company’s network. In Local Area Network
Infrastructure, there are user devices and switches for the communication over the network. This
communication is processed through the Fast Ethernet Copper Straight cable in this
infrastructure. Switches are connected through Gigabit Ethernet Copper Cross cable in the
existing network and the routers are connected through Serial Media cable. All these cables are
of different bandwidths (Voigt, et al., 2017).

Network Hardware
There is a list of network hardware which is used in designing this network:
1. Router - CISCO 2900 Router
Figure 2: CISCO Router
This router device is capable of the heavy workload and performance of this device is compatible
with company infrastructure. This router is compatible with HSRP and other protocols also.
There are many ways to configure and access this device.
2. Switch – CISCO SG350 Switch
Figure 3: CISCO switch
This device is available in three configurations, 12 switch port device, 24 switch port device, and
48 switch port devices. All three switch devices are very fast and support multiple protocols like
VTP, STP, etc. So these protocols can be easily configured over these switch devices.
3. Server AAA
This mentioned server is required in designing the network. This server is used to authenticate
the users who are using the company server at their home. For the configuration of this server,
the CISCO service is required to run and the RADIUS service is configured already in this
server.

4. Firewall - CISCO ASA 5500-X Firewall
Figure 4: CISCO Firewall
The security is the most important concern for an organization’s network. This introduced
firewall is implemented in the network infrastructure to provide the security of the network to
prevent unauthorized access (Patel & Sharma, 2017).
5. Access Point - CISCO Aironet 3600 Series
Figure 5: CISCO Access Point
This access point provides wireless connectivity to users or employees. This access point has
robust technology which makes it quite configurable and they can work with higher bandwidths.

Logical Network Design
Figure 6: Logical Network Design of AML
This figure is displaying the logical network of the Advance Medicos Limited company’s
network. All the enlisted components of this network are included in this diagram of the
network. There are two edge routers mentioned here one router is configured in building A and B
and the other one is configured at a far remote location. For maintaining the security over the
network there is a firewall placed and configured just next to the edge router. The
communication will be done after passing with the firewall, so the Local Area Network will
involve all the connected devices after the configuration and verification at the firewall. The
access point is configured in the network to provide wireless connectivity to the end users. There
is a server farm which is located in building B it makes the network private for the company. For
communication, users have to authenticate themselves to the server and then it provides access to
communicate through the network. This logical network design is perfect for the Advance
Medicos Limited company network and it will provide better communication and transmission
over the network (Singh, et al., 2018).

Network Physical Topology
Figure 7: Network Physical Topology of AML
This figure is displaying the network physical topology of the Advance Medicos Limited
network. All the required devices and components are showing in this diagram. This network
physical design has three components Building A, B and the far branch which is located at some
distance from the headquarters. This diagram depicts the devices connected through the network
and all the components in physical design or view. There are showing three floors in building A
and B. These buildings are connected through LAN and the distance office is connected through
the Wide Area Network (WAN) (Rimal, et al., 2017).
