TASK1: LOGICAL/PHYSICAL DESIGN OF NETWORKED SYSTEM
(P5)
I. DIFFERENCE BETWEEN TWO DESIGNS
A logical topology is how devices appear connected to the user. A physical topology is how they are
actually interconnected with wires and cables.
Logical design. The objective of the logical design phase is to reach, starting from the conceptual
scheme, a logical scheme that represents it faithfully, “efficiently” and independent of the

particular DBMS (Data Base Management System) adopted. To this end, this design phase can be
divided into 2 steps:
Restructuring of the Entity-Relationship scheme: it is a phase independent of the logical model and
is based on optimization criteria of the scheme;
Translation towards the logical model: it refers to a specific logical model, in our case the relational
model.
Physical design. It translates the logical schema in terms of tables and relationships that will
constitute the actual physical structure of the database. This last phase will be taken into
consideration in this thesis in a marginal way.

Figure 1. Logical Design Compared with Physical Design


II. USER REQUIREMENTS FOR GENERAL NETWORK DESIGN
1. User Request:


People: People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher
managers, including the head of academics and the program manager, 3 computer network
administrators.
 Resources: 50 student lab computers, 35 staff computers, 3 printers.
 Building: 3 floors, all computers and printers are on the ground floor apart from the IT labs –
one lab located on the first floor and another located on the second floor.
Explain the USER Requirement:

CEO Mr. Nguyen’s institution
Seconds Floor

•

Lab room 2: 25 computers (ITLab26 – ITLab50)

First Floor

•

Lab room 1: 25 computers (ITLab01 – ITLab25)

Ground Floor

•

Network administrators’ room: 3 computers.

•

Managers’ room: 5 computers and 1 printer.

•

Staff room: 12 computers and 1 printer.

•

Teachers’ room: 15 computers and 1 printer.


III. LOGICAL DESIGN
The logical network design is composed of segregated networks that are implemented physically
using virtual local area networks (VLANs) defined by network switches

Figure 2. Logical topology

IV. PHYSICAL DESIGN
The physical network design as the name implies, is the physical components used for installation.
Physical layout of a network is the hardware on which the network topology is built. The elements
of a physical network design consist of routers, cables, connecting cables, laptops, desktops,
switches

II. EVALUATION
Advantages:
 My design is simple, it is split into 3 floors
o Ground Floor: printers, teacher, manager and staff computer.
o Floor 1 and 2: For students and IT lab
 IP address is easy to remember and will tell where the machines are.
 Rooms are ping-able to each other with low latency
 The network has been divided into many VLANs, making it more secure than previously.
 High load capacity owing to two switches and two access points on each level, which
allow network devices to function normally during recess or peak hours.
Disadvantages:
 Incomplete firewall and security system
 If all rooms are running at maximum capacity at the same time, it is simple to run out of
network bandwidth.
 Upgrade the security and firewall system.
 In this design using a total of 8 switches and 1 multiple switch, it is generally quite
expensive
Solution

 Upgrade the system and firewall.
 If we have the budget, we should replace the layer 2 switch with a layer 3 switch so that
the connection lines are transmitted faster, moreover it also helps the network traffic
not to be congested during peak hours.


TASK 2.1: INSTALLATION AND CONFIGURATION (M3)
I. OVERVIEW OF SERVER
1. Definition of server
A server is a computer program or device that provides a service to another computer program and
its user, also known as the client. In a data center, the physical computer that a server program
runs on is also frequently referred to as a server. That machine might be a dedicated server or it
might be used for other purposes.
In the client/server programming model, a server program awaits and fulfills requests from client
programs, which might be running in the same, or other computers. A given application in a
computer might function as a client with requests for services from other programs and as a server
of requests from other programs

2. Why we need servers




Defense against viruses and other threats
Protection against losing data during a disaster
Compliance with industry requirements such as PCI-DSS and HIPAA
Key business software requires processing power and storage space
Secure remote access is critical to continued growth

II. CONFIGURATION DHCP_DNS Server
1. Purpose of DHCP server
A DHCP Server is a network server that automatically provides and assigns IP addresses, default
gateways and other network parameters to client devices. It relies on the standard protocol known
as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.
