• Why do standards architectures have multiple layers? To what does a standards layer provide services? If you change a standard at one layer, do standards at other layers need to be changed also? Why may it be advantageous to change a standard if the standard at the layer below it is upgraded?

• What is encoding? At what layer is the encoding of application messages done?

• What are QoS metrics? Why are QoS metrics important?

• Distinguish between rated speed and throughput. Distinguish between individual and aggregate throughput.

• What is availability? When should you measure error rates? Why? What is latency? What is jitter? Why may adding applications that cannot tolerate latency and jitter be expensive?
