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. 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.
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. 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.
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 Figure 3. Physical topology of ground floor 1. Ground floor Figure 4. Physical topology of ground floor Figure 5.

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.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 Figure 8. Illustration of servers 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. Configure default gateway and dns server 2. Purpose of DNS server The purpose of DNS is to translate a domain name into the appropriate IP address.
This is done by looking up the dns records of the requested domain. There are typically eight steps in this DNS lookup process that follow the information path from the originating web browser to the DNS server and back again. Configure service DHCP Figure 11. Configure service DNS II.
CONFIGURATION WEB Server 1. Purpose of Web server The primary role of a web server is to store, process, and deliver requested information or webpages to end users. It uses: Physical Storage: All website data is stored on a physical web server to ensure its safety. Configure default gateway and dns server III.
CONFIGURATION MAIL Server 1. Purpose of MAIL server a mail server collects and distributes emails to their intended destination. You can think of it as a computer that acts as an electronic post office for email, which allows you to control the transfer of emails within a network through different protocols. Figure 13 Configure default gateway and dns server Figure 14.
Configure services (adding email) IV. CONFIGURATION FILE Server 1. Purpose of FILE server A file server is a computer responsible for the storage and management of data files so that other computers on the same network can access the files. It enables users to share information over a network without having to physically transfer files.
Configure default gateway and dns server Figure 16. Configure service FTP (adding account) TASK 2. DESIGN NETWORK MAINTENANCE By implementing a network maintenance plan, you can keep your network running smoothly and without problems. My network maintenance programs aim to get rid of any networks that eventually end up costing your company money since they function poorly or fail when they're needed most.
Avoid waiting until your network fails by making use of my network maintenance plans, which include: Checking switches (2 monthly) Repair and Maintenance Switches are used to safely shut down machines and facilities that are not directly connected to a control unit or may bare the risk, that the machine or facility starts operating during maintenance or repair activities. Checking routers (3 monthly) Checking printers (4 monthly) Checking servers (2 weekly) Daily Physical check of your equipment. Every morning go into your server room and take a look and make sure that there are no red or amber lights. Check application and system event logs.
Go to your endpoint protection and delete inactive machines. 6 monthly Restart all servers not restarted in the past 6 months II. BENEFITS OF NETWORK MAINTENANCE Enhanced productivity Computer networks, like other business equipment, require regular maintenance in order to perform at their peak. A solid network monitoring and maintenance plan will ensure that all the critical aspects of the network are monitored for potential faults on a regular basis.
Some of the key areas of the network that require regular monitoring and maintenance include the system’s logs, antivirus system and the hard drives. A sound maintenance plan will make your business strong enough to overcome any anticipated situations thus reducing downtime incidents. Increased reliability A proactive maintenance plan will make the network company providing this service reliable to your business, its client. A proactive network monitoring and maintenance will result in satisfaction and a feeling of security.
The service provider too will receive negligible complaints against the machines since they are regularly monitored and maintained at a pre-set interval.
