Modular QoS Overview Differentiated Service Model for Cisco IOS XR Software Cisco IOS XR software includes traffic policing capabilities available on a per-class basis as well as class-based shaping. The traffic policing feature limits the input or output transmission rate of a class of traffic based on user-defined criteria, and can mark packets by setting values such as IP Precedence, QoS group, or DSCP value.
Page 23: Additional Cisco Ios Xr Qos Supported Features
Cisco IOS XR software. Modular QoS Command-Line Interface In Cisco IOS XR software, QoS features are enabled through the Modular QoS command-line interface (MQC) feature. The MQC is a command-line interface (CLI) structure that allows you to create policies and attach these policies to interfaces.

Page 251: Configuring Flow Aware Qos
Information About Flow Aware QoS Flow Aware QoS In Cisco ASR 9000 Series Routers, the granular control of traffic flow is achieved by applying static match criteria and associated QoS action on traffic flow. With real-time on-demand VoIP and video traffic applications, and tailor-made user services, there is an increasing need for the QoS actions to be more flow, application and session aware as opposed to being static, configuration based and stateless.
Page 252: Flow Aware Qos Key Terms
• Aggregate action—Aggregate action could either be a regular QoS action such as mark or set, which is enforced on each flow, but is common to all flows or an aggregate parent policer / queuing action enforced on all flows. Cisco ASR 9000 Series Aggregation Services Router Modular Quality of Service Configuration Guide, Release 6.1.x...
Page 253: Variants Of Flow Aware Qos
• CAC Rate—The user configurable total bandwidth for CAC admitted flows. It should be equal to or less than class service rate. Variants of Flow Aware QoS Two major feature variants of Flow Aware QoS supported in Cisco IOS XR Release 5.1.1 on Cisco ASR 9000 Series Routers are: • Call Admission Control (CAC) This variant is also known as Video Q or Flow aware CAC.
Page 254: Difference Between Regular Qos And Flow Aware Cac
