Quality of Service on Cisco Catalyst 4500 Series Supervisor Engines

Overview Quality of Service (QoS) provides the capability to differentiate among different classes of traffic and to prioritize the traffic in times of network congestion, according to its relative importance. The primary goals of QoS are to provide guaranteed minimum bandwidth for identified traffic, control jitter and latency (required by some real-time and interactive traffic) and to improve loss characteristics. This paper assumes the reader is familiar with basic QoS concepts such as classification, congestion avoidance, and bandwidth allocation. The objective of this paper is to provide an overview and configuration examples of the rich QoS capabilities available on the Cisco Catalyst 4500 Series supervisor engines.
