Brief of the Organization
The digital health institute Advanced Medicos Limited or AML is in the business of
selling healthcare products. By healthcare products AML refers to a variety of health related
services that they have been offering (Robert et al,. 2015). The key difference being, so far
AML has been providing healthcare specific services over through traditional methods like

paperwork and appointment booking through telephonic conversations. From now on the
medical institute is hoping to shift towards internet based services for streamlining these
processes and thereby speeding up the day to day operations and bringing efficiency as well
as effectiveness. Hence the institute is looking to upgrade their network infrastructure for
sustaining this change in requirements.
Requirements
The current physical network setup is based upon the network of AML headquarters
building which comprises of two wings buildings, building A and building B (Jorissen,
Boydens and Helsen 2019). These are basically the two wings of the company headquarters
and are situated 20m apart from one another. The current network is supposed to serve the
200 employees currently working in AML. The company Advanced Medicos Limited
consists of four departments, which are Software Department, Marketing, Production,
Administration. The departments, Software Department and Marketing are positioned in the
building A while the departments Production and Administration are positioned in the
building B. Each of these buildings consist of 3 different floors. The departments present in
these buildings are spread among these floors according to their size requirements. The
networks of the two buildings consist of switched based networks (Lévesque and Tipper
2016). Building B also acts as the server farm of AML.
The network equipment requirements of the current setup involves following network
hardware requirements for the four departments.

The software department requires 70 IP addresses for the workstations it operates and 10 IPs
for the printers installed (Dalle Mura, Dini and Failli 2016). The marketing department
requires 10 IP addresses for the workstations it operates and 4 IPs for the printers installed.
The production department requires 5 IP addresses for the workstations it operates and 2 IPs
for the printers installed (Azimi et al. 2016). The administration department requires 5 IP
addresses for the workstations it operates and 2 IPs for the printers installed.
The network equipment requirements of the propose setup involves following
network hardware requirements for the four departments.

The software department requires 70 IP addresses for the workstations it operates and 10 IPs
for the printers installed. Additionally, it needs IP addresses for supporting 65 laptops to
support the Bring Your Own Device (BYOD) functionality (Keyes 2016). The marketing
department requires 10 IP addresses for the workstations it operates and 4 IPs for the printers
installed.

The production department requires 65 IP addresses for the workstations it operates and 2 IPs
for the printers installed. The administration department requires 13 IP addresses for the
workstations it operates and 4 IPs for the printers installed.
The software department requires 18 IP addresses for the workstations it operates and 2 IPs
for the printers installed. It also needs IP addresses for supporting 5 laptops to support the
Bring Your Own Device (BYOD) functionality. The marketing department requires 4 IP
addresses for the workstations it operates and 2 IPs for the printers installed.
Networking Topologies
The various networking topologies used to implement the enterprise LAN network of
AML are LAN, WAN and WLAN. These topologies are illustrated below:

The logical design explains how the network is acquired from ISPs, routed through
respective routers, distributed through multilayer switches and accessed by devices from
switches of each floor.

Description and Analysis of current setup
Figure 4: Current physical setup
The current network involves the company AML acquiring internet services from the
services providers (ISP) (Hanafizadeh, Hatami and Bohlin 2019). AML receives the
connection through the edge router after passing it through a firewall device. This edge router
then routes the connection to the routers of buildings B and A which provides the connections
to the distribution and access layer switches (Wang, Chen and Yu 2017). The multilayer
switch obtain the network from the router and distributes it to the switches of the respective
floors (Gifre et al. 2018). The switches of each floor are responsible for providing access to
individual devices. These individual devices include workstations and printers and also
servers for building B. Since building B serves as the server farm it comprises of four servers
for catering to the networking and communication needs of the four departments.

10PHYSICAL NETWORK OF AML
Communication between the two buildings is carried over the web portal that is run
through the Local Area Network established between the two buildings (Du et al. 2017). The
web portal is only available for internal use by the company AML and is not accessible by
other users over the internet.
Since the building B and A are 20m or 100ft apart, the network can be sustained by
regular Cat 6 Ethernet cabling.
Description and Analysis of proposed setup
Figure 5: Proposed Network Solution

11PHYSICAL NETWORK OF AML
The proposed network makes some noteworthy changes. Apart from receiving the
connections through the edge router and routing it to the respective router of different
buildings and branches to provide connections to individual devices, the network involves
installation and use of wireless local area network connectors in building B and the branch.
Additionally, the branch network is added to the overall network. The branch network
comprises of two departments positioned in three floors of the building and also supports
BYOD services and hence requires WLAN connectors for providing wireless services (Patel
and Upadhyaya 2019). Here also a multilayer switch obtains the network from the branch
router which in turn gets it from building B and then distributes it to the switches of the
respective floors. The switches of each floor are responsible for providing access to
individual devices. These individual devices also include workstations and printers and also
servers for building B.
In this proposed network, not only additional workstations and printers are needed,
the building B which acts as the server farm requires five more servers. This is because the
server is now requiring three servers specifically for web hosting, email hosting and file
sharing. Other than that the building requires one server each for the 6 workplaces of the four
departments in the two buildings and the branch.
Here communication between the two buildings is also carried out over the web portal
but this time it is hosted by the web server at building B and is available to customers through
the internet. In this way online appointment and availing of healthcare services are facilitated.
Since the building B and the branch office are 100m or greater than 300ft apart, the
network cannot be sustained through regular Cat 6 Ethernet cabling (Goergen et al. 2019).
For this Cat 6A Ethernet cabling will be required.

IP Addressing and Calculations
The IP addressing method used for facilitating network connections for the individual
devices of the network is Classless Inter-domain Routing or CIDR as this one is more
efficient than the older classful IP addressing scheme where shifting from different classes
would result into massive differences in available address spaces (Koura, Zhang and Liu
2017). CIDR offers smoother transitions as smaller differentials in IP address spaces can be
noticed with help of incremental changes made to the CIDR value (Huang and Wang 2018).
Thus CIDR prevents IPs address space from getting wasted.
