1) Suppose that all of the network sources are bursty—that they only occasionally have data to send. Would packet-switching or circuit switching be more desirable in this case? Why?
2) What improvements do Switched Ethernet networks have over its predecessor Shared Ethernet networks?
3) What is DHCP, and what benefits and problems does dynamic addressing provide?
4) What does it mean when we say that control messages are “in-band”? What does it mean when we say that control messages are “out-of-band”? Give an example of a protocol that has inband control messages and an example of a protocol that has out-of-band control messages.
5) List and describe at least two issues that must be addressed in order to predict application-level performance between two network end points so that you can provision enough capacity to meet an application’s performance requirements.
