Most significantly, our technical experts have provided the effective and essential data about CBR in network simulator 2. Come let’s get to know about the significance of CBR in network simulator 2.

In general, CBR is denoted as the constant bit rate which is deployed along with TCP and UDP to design the traffic source behavior of the packets. Mainly in Ns2, the CBR is used in the networking streaming applications as the content which is capable to transfer over the limited channel capacity. The CBR traffic based on the parameters are highlighted in the following.

• Packet size
• Rate
• Interval
• Random
• Maximum packets

CBR Traffic Generator in Ns2

In addition, the CBR traffic generator is created and they are parameterized through the below mentioned commands.

set cbrobj [new Application/Traffic/CBR]

$cbrobj set packetSize_ 48

$cbrobj set rate_ 64Kb

$cbrobj set random_ 1

CBR Based Algorithm in Ns2

Moreover, we have highlighted some algorithms which are implemented in Ns2 for CBR based process.

• Heuristic algorithm
• Optimal smoothing work ahead algorithm
• 3RCBR (Renegotiated constant bit rate)

As the end note, we are assuring that we provide the complete support for the research scholars. So, you can reach us at anytime.
