High Quality Content by WIKIPEDIA articles! The NetEqualizer is a bandwidth shaping system designed for voice and data networks created by APconnections in 2003. NetEqualizer appliances use built-in fairness rules to automatically shape traffic. Based on current network usage, traffic is controlled by application-level traffic shaping. When the network is congested, the fairness algorithm favors business class applications at the expense of large file downloads, such as those seen with peer-to-peer file sharing. The favored applications include those such as VoIP, Web browsing, chat and email.
