Challenge Problems
Push your limits with advanced challenges
Given a router where 30 packets arrive every minute and it can only process 12 packets per minute, analyze the impact on average waiting time and packet loss if this trend continues.
💡 Hint: Think about how the imbalance between arrival and service rates creates bottlenecks.
How would changing the service rate of a router from 10 packets/min to 20 packets/min influence the average queue length (Lq) in a scenario with a constant arrival rate of 15 packets/min?
💡 Hint: Visualize a bus that has more seats (service rate) than passengers (arrival rate).
