Computer Networking Projects For Students

Computer Networking Projects For Students helps to the academic B.TECH / M.TECH / MS / PHD students.

Computer Networking Projects For Students

• Computer network is the linking of multiple devices which are connected by external cable or wireless media.
• Computers can be geographically located anywhere
• It is used for sharing of information between network devices it may be client server.
• Communication is the main aim of computer networks

Server:

• In computer networks, a server is considered any instance of an application.
• It can receive and serve the requests of other programs.
• Usually servers include
  • faster CPUs
  • bigger hard drives
  • better RAM
  • Multiple power sources.

Resources of computer networks

• Printers
• CDs
• Files
• Even electronic communications such as e-mails and instant messages

Types of Internet Connections:

• Broadband
  • Wi-Fi
  • WiMAX

Network Topology:

• Topology of the network defines in which way the network devices are connected.
• It defines the layout of both wireless and wired devices.
• It also defies path used for packet transmission.

Types of network topology:

• Bus topology
• Star topology
• Ring topology
• Mesh topology
• Tree topology
• Line topology
• Fully connected topology

set ns [new Simulator]

#———-creating nam objects—————-#

set nf [open tcp1.nam w]
$ns namtrace-all $nf

#open the trace file
set nt [open tcp1.tr w]
$ns trace-all $nt

set proto rlm

$ns color 1 blue
$ns color 2 yellow
$ns color 3 red

#———- creating client- router- end server node—————-#

set Client1 [$ns node]
set Router1 [$ns node]
set Endserver1 [$ns node]

#—creating duplex link———#

$ns duplex-link $Client1 $Router1 2Mb 100ms DropTail
$ns duplex-link $Router1 $Endserver1 200Kb 100ms DropTail

#—————creating orientation——————#

$ns duplex-link-op $Client1 $Router1 orient right
$ns duplex-link-op $Router1 $Endserver1 orient right

#————Labelling—————-#

$ns at 0.0 “$Client1 label Client1”
$ns at 0.0 “$Router1 label Router1”
$ns at 0.0 “$Endserver1 label Endserver1”

#———–Configuring nodes————#

$Endserver1 shape hexagon
$Router1 shape square

#—————-Establishing queues———#

#$ns duplex-link-op $Client1 $Router1 queuePos 0.1
#$ns duplex-link-op $Router1 $Endserver1 queuePos 0.5

#———finish procedure——–#

proc finish {} {
global ns nf nt
$ns flush-trace
close $nf
close $nt

puts “running nam…”
exec nam tcp1.nam &
exit 0
}

#Calling finish procedure
$ns at 6.0 “finish”
