Configuring Modular Quality of Service Congestion Management on Cisco IOS XR Software

Congestion management controls congestion after it has occurred on a network. Congestion can be managed on Cisco IOS XR software by using packet queueing methods, and by shaping the packet flow through use of traffic regulation mechanisms.

Packet queueing methods define packet scheduling or the order in which packets are dequeued to the interface for transmission on the physical wire. Furthermore, queueing methods support minimum bandwidth guarantees and low latencies based on the order and number of times that a queue is serviced.

The following types of queueing methods and traffic regulation mechanisms are supported on the Cisco IOS XR software:

•Modified Deficit Round Robin (MDRR)

•Low-latency queueing (LLQ) with strict priority queueing (PQ)

•Traffic shaping

•Traffic policing

This module provides the conceptual and configuration information for Quality of Service (QoS) packet queueing methods and traffic regulation mechanisms on Cisco IOS XR software.

Note For additional conceptual information about QoS in general and complete descriptions of the QoS commands listed in this module, see the “Related Documents” section of this module. To locate documentation for other commands that might appear in the course of executing a configuration task, search online in the Cisco IOS XR software master command index.
