Consider the following two arrival patterns of packets at a router: • (A) N packets arrive simultaneously in the 1st timestep and no other packets arrive during the N- 1 following timesteps. • (B) There is a sequence of N timesteps with one packet arriving every second timestep. Mark all correct statements: O (A) will incur a larger average queuing delay compared to (B). O The traffic intensity is exactly 1 for (A). O The traffic intensity is exactly 1 for (B).

Transcribed Image Text:Consider the following two arrival patterns of packets at a router:
• (A) N packets arrive simultaneously in the 1st timestep and no other packets arrive during the N-
1 following timesteps.
• (B) There is a sequence of N timesteps with one packet arriving every second timestep.
Mark all correct statements:
O (A) will incur a larger average queuing delay compared to (B).
O The traffic intensity is exactly 1 for (A).
O The traffic intensity is exactly 1 for (B).
O (B) will incur a larger average queuing delay compared to (A).
The queuing delay for both (A) and (B) will be roughly the same.
