- Suppose a network failed on the average once every 2500 hours and it took about 2 hours to be fixed.
- What is the availability of that network as a percent?

- What is Lambda for that network?

- A system has five components with MTBF’s 8000, 12000, 20000, 6000, 11000 and 40000 hours respectively.
- What are the lambdas for each component?

- What is the lambda for the composite system?

- What is the MTBF for the composite system?

- A switch has 26 ports each transmitting 30 packets per second. Each packet is 1024 bits. The switch can handle 1.54 mbps.
- What is the utilization rate for the switch?

- What is the average number of packets in the queue?
