These packets carry data for many different applications to many different destinations. If the amount of traffic arriving is less than the ... en-us Dropping Packets and Congestion Avoidance http://ciscoarticles.com/rss/article_view.php?articleId=1316 Copyright 2013, 2008-07-21T00:00:00+03:00 text http://ciscoarticles.com/Cisco-IOS/1315.html Custom Queueing <a name="Id10998e0_846203" /><a name="Id11001e0_846410" />Custom Queueing (CQ) is one of Cisco's most popular queueing strategies. CQ was originally implemented to address the clear shortcomings of PQ. It lets you configure how many queues are to be used, what applications will use which queues, and how the queues will be ... en-us Custom Queueing http://ciscoarticles.com/rss/article_view.php?articleId=1315 Copyright 2013, 2008-07-21T00:00:00+03:00 text http://ciscoarticles.com/Cisco-IOS/1314.html Priority Queueing <a name="Id10992e0_846201" /><a name="Id10995e0_846412" />Priority Queueing (PQ) is an older queueing algorithm that handles traffic with different precedence levels much more pragmatically. The Cisco implementation of Priority Queueing uses four distinct queues called "high priority," "medium priority," "normal priority," and "low priority." The PQ algorithm maintains an extremely strict ... en-us Priority Queueing http://ciscoarticles.com/rss/article_view.php?articleId=1314 Copyright 2013, 2008-07-21T00:00:00+03:00 text http://ciscoarticles.com/Cisco-IOS/1313.html Relative share of bandwidth in WFQ by IP precedence Precedence name Value Relative share of bandwidth Routine 0 1 Priority 1 2 Immediate 2 3 Flash 3 4 Flash Override 4 5 Critical 5 6 Internetwork Control 6 7 Network Control 7 8 These fair queueing algorithms tend to do three things.
