Extreme network equipment is designed for deploying Voice-over-IP
(VoIP) services in the enterprise environment. While common
applications such as file transfer or web access do not need Quality
of Service (QoS) mechanisms in most environments, popular voice
encoding algorithms might need support from QoS mechanisms in some
network environments. In enterprise networks where congestion might
occur, deploying QoS mechanisms can provide significant improvements
to the quality of VoIP service. 
Wherever QoS is deployed, the network should be outfitted with
equipment supporting a full 8 queues per port, flexible QoS queuing
and scheduling algorithms, both minimum and maximum bandwidths for
each queue, and flexible ACLs to ensure that the correct QoS marking
is applied to each packet and to filter out unauthorized traffic.
Networked devices, whether VoIP handset or a traditional computer
workstation, should support appropriate marking of IP Precedence and
Ethernet Precedence fields. Following these guidelines will help
ensure a successful deployment and optimal network performance
during periods of stress. 
It is also important to select and deploy networking equipment
that has ASIC-based implementations of ACLs, VLANs, Ethernet
bridging, and IP forwarding. This helps ensure that enabling
important features does not reduce network performance, and the
latency through the switch or router is minimized. While CPU-based
implementations are becoming less common due to their inherent
technical problems, some equipment being sold today still places
important capabilities inside the main CPU because that equipment
does not have ASIC support for these features.
