4.6 Quality of Service
Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control over network traffic.
QoS enables you to assign various grades of network service to different types of traffic, such as multi-media, video,
protocol-specific, time critical, and file-backup traffic.
QoS reduces bandwidth limitations, delay, loss, and jitter. It also provides increased reliability for delivery of your data and
allows you to prioritize certain applications across your network. You can define exactly how you want the switch to treat
selected applications and types of traffic.
You can use QoS on your system to:
。 Control a wide variety of network traffic by:
。 Classifying traffic based on packet attributes.
。 Assigning priorities to traffic (for example, to set higher priorities to time-critical or business-critical applications).
。 Applying security policy through traffic filtering.
。 Provide predictable throughput for multimedia applications such as video conferencing or voice over IP by
minimizing delay and jitter.
。 Improve performance for specific types of traffic and preserve performance as the amount of traffic grows.
。 Reduce the need to constantly add bandwidth to the network.
。 Manage network congestion.
