1. How does data traffic differ from voice traffic?

2. Estimate the computational power needed to implement fine-grain QoS in the core of the Internet: assume a 10 Gbps link delivering 1000 byte packets and N arithmetic operations per packet, and calculate the number of operations a processor needs to perform per second.

3. What are the two types of QoS?

4. What four parameters are used to characterize a VBR flow?
