Getting Started

In This Chapter

This chapter provides process flow information to configure Quality of Service (QoS) policies and

provision services.

This guide provides information to configure QoS policies in both network mode and access-

uplink mode. Unless otherwise noted, many of the qos policies are applicable to both network

mode and access-uplink mode.

QoS Overview

Page 20 7210 SAS M OS Quality of Service Guide

QoS Overview

The 7210 SAS M is designed with QoS mechanisms on both ingress and egress to support multiple

services per physical port. The 7210 SAS M has extensive and flexible capabilities to classify,

police, shape, and mark traffic.

In the Alcatel-Lucent service router’s service model, a service is provisioned on the provider-edge

(PE) equipment. Service data is encapsulated and then sent in a service tunnel to the far-end

Alcatel-Lucent service router where the service data is delivered.

The operational theory of a service tunnel is that the encapsulation of the data between the two

Alcatel Lucent service routers appear like a Layer 2 path to the service data although it is really

traversing an IP or IP/MPLS core. The tunnel from one edge device to the other edge device is

provisioned with an encapsulation and the services are mapped to the tunnel that most

appropriately supports the service needs.

The 7210 SAS supports eight forwarding classes internally named: Network-Control, High-1,

Expedited, High-2, Low-1, Assured, Low-2 and Best-Effort. The forwarding classes are discussed

in more detail in Forwarding Classes on page 81.

7210 SAS devices use QoS policies to control how QoS is handled at distinct points in the service

delivery model within the device. There are different types of QoS policies that cater to the

different QoS needs at each point in the service delivery model. QoS policies are defined in a

global context in the 7210 SAS and only take effect when the policy is applied to a relevant entity.

QoS policies are uniquely identified with a policy ID number or name. Policy ID 1 or Policy ID

“default” is reserved for the default policy which is used if no policy is explicitly applied.

The QoS policies within the 7210 SAS can be divided into three main types:

• QoS policies are used for classification, defining metering and queuing attributes and

marking .

• Slope policies define default buffer allocations and WRED slope definitions.

• Port scheduler policies determine how queues are scheduled.
