About This Guide

This guide describes Quality of Service (QoS) provided by the 7210 SAS-X and

R6 presents examples to configure and implement various protocols and services.

On 7210 SAS devices, not all the CLI commands are supported on all the

platforms and in all the modes. In many cases, the CLI commands are mentioned

explicitly in this document. In other cases, it is implied and easy to know the CLIs

that are not supported on a particular platform.

This user guide is applicable to all, 7210 SAS-R6 and 7210 SAS-X platforms,

unless specified otherwise. 7210 SAS-X and 7210 SAS-R6 does not support

access-uplink mode. 7210 SAS-X and 7210 SAS-R6 supports only MPLS uplinks

and implicitly operates in network mode.

This document is organized into functional chapters and provides concepts and

descriptions of the implementation flow, as well as Command Line Interface

(CLI) syntax and command usage.

QoS Overview

Page 18 7210 SAS-X and 7210 SAS-R6 OS Quality of Service Guide

QoS Overview

The 7210 SAS-X and 7210 SAS-R6 is designed with QoS mechanisms on both ingress and egress

to support multiple services per physical port. The 7210 SAS-X 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 68.

7210 SAS 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, ingress policing, egress queue attributes, and

marking.

• Queue management policies define buffer allocations and WRED slope definitions.

• Scheduler policies determine how queues are scheduled.

7210 SAS-X and 7210 SAS-R6 OS Quality of Service Guide Page 19

QoS Policies

7210 SAS-X QoS policies are applied on service ingress, service egress, network port ingress and

egress, and network IP interfaces These policies allow user to configure the following:

• Classification rules for how traffic is mapped to forwarding classes

• Forwarding class association with meters and meter parameters used for policing (rate-

limiting).

• Queuing parameters for shaping, scheduling, and buffer allocation

• QoS marking/interpretation

There are several types of QoS policies:

• Service ingress

• Service egress

• Network (for ingress and egress)

• Network queue (for egress)

• Scheduler

• Queue Management

• Remark policies

Service ingress QoS policies are applied to the customer-facing Service Access Points (SAPs).

Traffic that enters through the SAP is classified to map it to a Forwarding Class (FC). Forwarding

class is associated with meters on ingress. The mapping of traffic to meters can be based on

combinations of customer QoS marking (IEEE 802.1p bits), IP and MAC criteria. The

characteristics of the forwarding class meters are defined within the policy as to the number of

forwarding class meters for unicast traffic and the meter characteristics (like CIR, PIR, etc.). Each

of the forwarding classes can be associated with different unicast parameters. A service ingress

QoS policy also defines up to three (3) meters per forwarding class to be used for multipoint traffic

for multipoint services. There can be up to 32 meters in total per Service ingress QOS policies. In

the case of the VPLS, four types of forwarding are supported (which is not to be confused with

forwarding classes); unicast, multicast, broadcast, and unknown. Multicast, broadcast, and

unknown types are flooded to all destinations within the service while the unicast forwarding type

is handled in a point-to-point fashion within the service.

Service egress QoS policies are applied to SAPs and map forwarding classes to service egress

queues for a service. The system allocates 8 queues per SAP for the 8 forwarding classes. A

service egress QoS policy also defines how to remark the forwarding class to IEEE 802.1p bits in

the customer traffic.

There are two types of network QoS policies, one applied to a network IP interface and the other

type is applied to a network port. On ingress, the policy applied to an IP interface maps incoming

QoS Overview

Page 20 7210 SAS-X and 7210 SAS-R6 OS Quality of Service Guide

values to forwarding class and profile state for the traffic received from the core network. On

egress, the policy maps forwarding class and profile state to values for traffic to be transmitted

into the core network. The network policy applied to a network port maps incoming IP packets,

DSCP or Dot1p values, to the forwarding class and the profile state for the traffic received from

the core network. On egress, the policy maps forwarding class and profile state to DSCP and/or

Dot1p values for IP traffic to be transmitted into the core network.

Network queue policies are applied on egress to ports . The policies define the forwarding class

queue characteristics for these entities. The FCs are mapped onto the queues. There are 8 queues at

the port level. FC-to-queue mapping is static and is not configurable. The number of queues are

static and service are always 8 queues at the port level.

Service ingress, service egress, and network QoS policies are defined with a scope of either

template or exclusive. Template policies can be applied to multiple entities (such as SAPs and

ports) whereas exclusive policies can only be applied to a single entity.

One service ingress and one service egress QoS policy can be applied to a specific SAP. One

network QoS policy can be applied to a specific IP interface or network port based on the type of

network QoS policy . A network QoS policy defines both ingress and egress behavior. One

network queue policy can be applied to the network port.

If no QoS policy is explicitly applied to a SAP, port or interface, a default QoS policy is applied.
