Queuing (Scheduling) The most popular QoS tool, queuing, involves choosing the packets to be sent based on something other than arrival time. In other words, instead of FIFO queuing with one queue, other queuing mechanisms create multiple queues, place packets into these different queues, and then pick packets from the various queues. As a result, some packets leave the router more quickly, with other packets having to wait longer. Although queuing does not decrease delay for all packets, it can decrease delay for delay-sensitive packets, and increase delay for delay-insensitive packets—and enabling a queuing mechanism on a router does not cost any cash, whereas adding more bandwidth does.

Quiz questions that correspond to those topics. book Page 4 Tuesday, October 19, 2004 1:40 PM 4 Chapter 1: QoS Overview CAUTION The goal of self-assessment is to gauge your mastery of the topics in this chapter.

Giving yourself credit for an answer you correctly guess skews your self-assessment results and might provide you with a false sense of security.
