Network Design Report: Top Class Networks - Module: Networking

This report outlines a network design for Top Class Networks, a Sydney-based networking firm occupying a five-floor building with five departments: Administration, Customer Support, Hardware, HR, and Sales. The report begins with an introduction that analyzes networking requirements, followed by a detailed Local Area Network (LAN) design for all departments, including IP addressing and subnetting schemes to ensure efficient resource access and inter-departmental data transfer. The design incorporates point-to-point topology and considers the physical layout, including switch placement and firewall configuration. The report also provides a complete IP addressing scheme for all computers and printers in each department. The report concludes with a discussion of network topology, IP addressing, and subnetting, along with recommendations to enhance communication and promote Top Class Networks' business outcomes.

Introduction
Top Class Networks is a small networking firm in Sydney. The office occupies a five floor
building. The company has five main departments: Administration, Customer Support,
Hardware, HR and Sales. Administration is on the first floor, Customer Support is on the second
floor, Hardware is on third floor, HR is on fourth floor and Sales is on the fifth floor.
Administration has 42 workstations, Customer Support has 62 workstations, Hardware has 57
workstations, HR has 67 workstations and Sales has 72 workstations.
Requirements
 All the computers must have latest Windows 10 operating system updates
 Top Class Networks must have good physical and layout set up
 Upgrading of printers and computers in all the departments
 All departments must access resources from one common place.
Design and implementation
Network Topology
Point to point topology
A point-to-point system is perhaps the most straightforward system since it just includes two
hubs. Every hub is associated with the other with one association line. This is one of the least
expensive and best arrange models since it doesn't include the expense of redundancies and it
doesn't include the unpredictability of requiring a few hubs working to make an
association(Bordin, Gordini, and Vigo, 2016).

3
Be that as it may, the point-point system is illogical from a systems administration viewpoint
because once in a while is just a single association between two hubs sufficient. The point-to-
point mode can be contrasted with two soup jars associated by a string. Even though there is
nothing to interfere with the association, the system cannot branch out and make more
associations(Ceselli, Premoli, and Secci, 2015, May).
A genuine case of a point-to-point system is a PC that is associated with a nearby printer by a
USB link. Albeit exceptionally solid, there is no chance to get for either hub to associate with
whatever else utilizing that one USB association. Likewise, with no repetition, the whole
association is reliant on the USB link also(Eskandarpour et al., 2015).
Advantages
a) Most noteworthy Bandwidth because just two hubs are having a whole
transmission capacity of a connection
b) Extremely quick contrasted with other system topologies since it can get to just
two hubs(Rezapour, Farahani, and Pourakbar, 2017).
c) Fundamental availability
d) It gives low Latency.
c) Straightforward to deal with and keep up
d) Hub Can be Replaced in a couple of moments seconds(Govindan, Paam, and
Abtahi, 2016).

Hardware
The second floor comprises of 2 center switches, two center switches, firewall, entryway switch,
server room and a peaceful area (DMZ) which hosts web server for Inside access just as for
outside access. The motivation to utilize two center switches is to give excess and to keep away
from a sole purpose of disappointment (SPOF). Fiber optic links turning out from the switch case
in each floor and the switch inside the server room is ending in every one of these center
switches independently(Soleimani et al., 2017). These center switches are likewise
interconnected between them. Center switch is utilized to course traffic inside the structure
(among VLANs) and to course traffic outside of the structure (To Internet and other branch
workplaces). The motivation to utilize two center switches is to give repetition and to keep away
from a sole purpose of disappointment. 2 center switches likewise interconnected among them
and associated with two center switches utilizing rapid links independently. DMZ (to isolate it
from within the system) is made to have the webserver because it is thought to be gotten to by

insiders just as untouchables. Along these lines, on the off chance that any gatecrashers attempt
to assault the webserver, at that point, harm to the entire system (framework) will be limited. The
web server in DMZ is legitimately associated with the firewall utilizing a fast link. A firewall is
used to channel traffic that is coming toward within system. This is accomplished using the
entrance control list (ACL) arranged inside the firewall. A firewall is associated with center
switches and web server the inside way and associated with the door switch and Internet in its
outside ways.
The door switch is utilized to advance/course the traffic to other legitimately associated branch
workplaces through the rented lines (Assuming branch workplaces are associated with the
leading site through the occupied lines as they are arranged near one another and requires
enormous information move to the leading site)(Szeto et al., 2015).

Conclusion and recommendations
In business, the network is significant for correspondence among client and customer, so IP must
assign to every gadget associated in the system to convey. An open IP address is paid and given
by ISP which is interesting and doles out to the switch, and distinctive server and every PC,
versatile and different gadgets associate with switch allot private IP address through DHCP
convention. A Public IP address appoint gadget can access over the web, yet private IP address
relegates gadget can access over the web through open IP address by system address interpreter,
so every association needs remarkable IP address which is secure to access and move record and
asset.
Top Class Networks is little organization, that division prerequisite must satisfy, and
arrangement PC arrange that guarantee all representative must access all record and asset of the
organization as per the organization strategy. The consistent and physical format must be
actualized alongside arranging and structure that improve communication between various
offices that helps to advance Top Class Networks results.
