A. FIFO queuing， which provides a means to hold packets while they are waiting to exit an interface
B. Priority queuing， which ensures a fixed amount of bandwidth
C. Custom queuing （CQ）， which provides a queuing tool that services all queues， even during times of congestion
D. Bandwidth queuing， which ensures a minimum amount of bandwidth
E. Weighted fair queuing （WFQ）， which classifies packets based on flows
A. It supports admission control that allows a network to reject or downgrade new RSVP sessions if one of the interfaces in the path has reached the limit （that is， all reservable bandwidth is booked）.
B. RSVP signals QoS requests per individual flow. In the request the authorized user （authorization object） and needed traffic policy （policy object） are sent. The network can then provide best-effort delivery to these individual flows.
C. RSVP streamlines communication by making it unnecessary to inform network devices of flow parameters （IP addresses and port numbers）.
D. Because of the stateful RSVP architecture， continuous signaling does not have to occur.
E. The flow-based approach is scalable to large implementations， such as the public Internet， because RSVP tracks each individual flow.

A. Packets can arrive out of order.
B. Packets must take the same path to the destination.
C. Once packets are received at the destination router， the router performs sampling to ensure the quality of the voice traffic.
D. Packets can experience varying delays across the network.
E. Packets containing voice samples are sequentially numbered by default， allowing for reordering upon arrival at the terminal router along the path.
A. Compress payload.
B. Use header compression.
C. Increase link capacity.
D. Use random early detection.
E. Guarantee bandwidth to fragile flows.
F. Implement network-based application recognition.
