NETWORK PROJECT

Network project is to provide vastly available and also accessible environs intended for the connection of Internet and application services. We offer great specialist contact to scholars. In addition, network project ensures that an enabler envisioned for viable project schemes for researchers.

Network Objectives

• A series of points are interconnected together via a communication path.
• It also makes communication between computer devices
• In all data, the Network consists of nodes
• The physical connection also between nodes are links
• Links carry message also between nodes

Need for computer networks

• File sharing
• Data protection
• Resource sharing
• Remote access
• Communication and also collaboration

Network Characteristics

• Availability
• Reliability
• Security
• Topology
• Cost
• Speed
• And also Scalability

Devices to connect Network

• Routers
• Gateways
• Repeaters
• Bridges
• Hub
• And also Modem

Network Topologies

• Bus topology
• Star topology
• Mesh topology
• Topology – Ring
• Hybrid Topology
• And also Wireless Topology

Factors for choosing network topology

• Topology defines the virtual structure of a network
• Also, Topology may be physical or logical
• The main factors also for choosing network topologies are,
• The scale of your project -the number of components also to be connected
• The amount of traffic expected also based on the Network
• The Budget also allotted for the Network
• And also in Required response time

   Our Network project very dependable and delivers 100% uptime for everyone. We are ranked No 1 in industry to implement network projects or network simulation projects using various network simulation tools

Criteria for choosing network type

• Size of the business
• Level of security required
• Type of activity
• Skills of the administrators available
• The volume of traffic also over the Network
• Needs of the Network’s users
• And also Budget set aside for operating the Network

#Create a simulator object

#Open the NAM trace file

set nf [open o.nam w]

$ns namtrace-all $nf

# create nodes

set n0 [$ns node]

set n1 [$ns node]

set n2 [$ns node]

set n3 [$ns node]

set n4 [$ns node]

#Create links between the nodes

$ns duplex-link $n0 $n2 2Mb 10ms DropTail

#Define a ‘finish’ procedure

proc finish {} {

$ns flush-trace

#Close the NAM trace file

close $nf

#Execute NAM on the trace file

exec nam o.nam &

exit 0}

#Call the finish procedure

$ns at 1.0 “finish”

#Run the simulation $ns run
