Approximately 1.336 packets will be present in the buffer after a 2-second duration under these conditions
How to solve
To find the number of packets in the buffer after 2 seconds, we first need to calculate the rate of packet arrival per millisecond:
Total packets arriving per millisecond = Total packets arriving / Total time (in milliseconds)
Total packets arriving per millisecond = 2911 packets / (2 seconds x 1000 milliseconds/second)
Total packets arriving per millisecond = 2911 packets / 2000 milliseconds
Total packets arriving per millisecond ≈ 1.4555 packets per millisecond
Now, we can determine the number of packets in the buffer after 2 seconds:
Number of packets in the buffer = Queuing delay (in milliseconds) x Rate of packet arrival per millisecond
Number of packets in the buffer = 0.918 milliseconds x 1.4555 packets per millisecond
Number of packets in the buffer ≈ 1.336 packets
Therefore, approximately 1.336 packets will be present in the buffer after a 2-second duration under these conditions
The Complete Question
Assuming an infinite router buffer and a queuing delay of 0.918 milliseconds, a total of 2911 packets arrive at the router. How many packets will be present in the buffer after a 2-second duration?
