Network Design and Configuration - Prof. Omar, Slides of Computer Networks

An overview of a network design and configuration process, including the physical and logical topology, device specifications, and the installation and configuration of various network services and applications. The setup of a dns server, dhcp servers, an http server, and an email server, as well as the configuration of routers and client devices. It also includes the results of network testing and troubleshooting. The document highlights the importance of network design, device selection, and the implementation of network services to support the growth and communication needs of the organization. It emphasizes the benefits of wireless access, the concept of ip addresses and port numbers, and the overall conclusion that computer networks can vary in scale and complexity, from small local networks to nationwide infrastructures.

II. Task 1: Provide a logical/physical design of the networked system with clear explanation and addressing table a) Difference between physical design and logical design

  • Physical topology indicates arrangement of different elements of a network. It reflects

physical layout of devices and cables to a form a connected network. It is concerned with

essentials of network ignoring minute details like transfer of data and device type. The pattern

of arrangement of nodes (computers) and network cables depends on ease of installation and

setup of the network. It affects cost and bandwidth capacity based on solution of devices. It

considers placement of nodes and distance between them. Devices can be arranged to form a

ring (Ring Topology) or linearly connected in a line called Bus Topology.

Figure 1 : Example of Physical design

  • Logical Topology reflects arrangement of devices and their communication. It is the

transmission of data over physical topology. It is independent of physical topology, irrespective

of arrangements of nodes. It is concerned with intricate details of network like type of devices

(switches, routers) chosen and their quality, which affect rate and speed of data packets

delivery. The logical topology ensures optimal flow control that can be regulated within

network.

Figure 2 : Example of Logical design

  • The basic difference between Logical and physical address is that Logical address is

generated by CPU in perspective of a program. On the other hand, the physical address is a

location that exists in the memory unit. The set of all logical addresses generated by CPU for a

program is called Logical Address Space.

  • A design was created using the connections and devices that were available and the needs of

the situation. There are servers first, such as the DNS server, HTTP server, and DHCP server.

Depending on the needs and preferences, the devices are set up with various levels and

functionality those users.

  • The student and teacher floor, which includes a switch, DHCP server, and classroom labs for

both students and teachers, is located on the first floor.

  • On the second floor, in addition to the appearance of a wireless connection, there is another

DHCP of the Marketing and Management sector with labs.

  • The third floor is where the administrators are located, and it is also a very secure level. mostly

includes servers like DNS servers and HTTP servers

III. Task 2: valuate the design to meet the requirements

  • To check if the network is working or not, we need to ping all the devices and see if they have

any address problems.

  • Advantages of this design:

+ can easily connect new devices such as phones or tablets,...

+ easy construction and low cost

  • Disadvantages of the design:

+ Simple design and not yet modern

+ Difficult to check and maintain periodically

+ If there is a problem with the wire, it will be difficult to find and repair

  • This type of network depends a lot on physical cable, so its work effectively when we set the

bandwidth limitation for the un-needed devices or using better and multiple cable.

Figure 7 : Enter IP

+ Then we need to edit the domain name

Figure 8 : Edit DHCP for DNS server

Figure 9 : Set DNS domain name

+ Next, we need to edit website content

Figure 10 : Edit content for website

Figure 13 : Set IP for PC

+ Do the same for each device

Figure 14 : Set IP for the second PC Click here to set IP automatically

Figure 15 : Set IP for the second PC

+ Please test your pass and make sure it works properly by pinging each device.

+ Try searching on all the devices you have. That's it, you've completed a basic DNS service.

V. Task 3: Implement a networked system based on a prepared design

  • Set up all the devices and add the necessary things.

+ Configure DHCP 1 server
