Queueing in Internetworking and Congestions

Let the three variables:

• $b$ is the bandwidth (bits/s)
• $s$ is the size of a packet (bits)
• $a$ is the arrival rate (count/sec)

Then we can know that:

• $s \times a$ is the traffic arrival rate (bits/s)
• If $$, the bandwidth is much higher than the traffic. No problem.
