Configuring SQA

About SQA

Service quality analysis (SQA) enables the device to identify SIP-based multimedia traffic and preferentially forward this traffic to ensure multimedia service quality. Use this feature to decrease multimedia stuttering and improve user experience of a service template.

Restrictions and guidelines: SQA configuration

SQA does not support analysis of encrypted SIP protocol packets or fragments.

For SIP-based SQA to take effect on a service template bound to a radio, do not enable fast forwarding of AP-to-client data frames for the radio (see WLAN optimization in WLAN Advanced Features Configuration Guide).

SQA configuration tasks at a glance

To configure SQA, perform either of the following tasks:

·     Configuring SQA

Choose the following tasks as needed:

¡     Configuring SIP-based SQA

¡     Configuring SQA for audio and video traffic

·     (Optional.) Configuring statistics collection for endpoint application traffic

Configuring SIP-based SQA

1.     Enter system view.

system-view

2.     Create an SQA profile and enter its view.

sqa profile profile-name

3.     Enable SIP-based SQA in the SQA profile.

sip enable

By default, SIP-based SQA is disabled in an SQA profile.

4.     Return to system view.

quit

5.     Enter service template view.

wlan service-template service-template

6.     Bind an SQA profile to the service template.

sqa-profile profile-name

By default, no SQA profile is bound to a service template.

Configuring SQA for audio and video traffic

About this task

After SQA is enabled, the service template bound to the SQA profile will analyze the audio and video traffic of wireless endpoints. The service template also collects and saves basic information ( such as source and destination IP addresses) and quality information (such as delay and jitter) about the audio and video streams. The device can report the analysis data to a control terminal through NETCONF. For information about NETCONF, see Network Management and Monitoring Configuration Guide.

Restrictions and guidelines

This feature is supported only in local forwarding mode.

Procedure

1.     Enter system view.

system-view

2.     Create an SQA profile and enter its view.

sqa profile profile-name

3.     Enable SQA for an audio or video application.

application app-name enable

By default, SQA is disabled for all audio and video applications.

4.     (Optional.) Specify the interval at which analysis data for audio and video applications is collected and sent.

application interval interval

The default setting is 300 seconds.

5.     Return to system view.

quit

6.     Enter service template view.

wlan service-template service-template

7.     Bind an SQA profile to the service template.

sqa-profile profile-name

By default, no SQA profile is bound to a service template.

Configuring statistics collection for endpoint application traffic

About this task

After this feature is enabled, the service template bound to the SQA profile will collect traffic statistics on identifiable applications for wireless endpoints. The device can report the statistics to a control terminal through NETCONF. For information about NETCONF, see Network Management and Monitoring Configuration Guide.

Restrictions and guidelines

This feature is supported only in local forwarding mode.

Procedure

1.     Enter system view.

system-view

2.     Create an SQA profile and enter its view.

sqa profile profile-name

3.     Enable statistics collection for endpoint application traffic.

application statistics enable

By default, statistics collection for endpoint application traffic is disabled

4.     (Optional.) Specify the interval at which traffic statistics are collected and sent.

application statistics interval interval

The default setting is 5 minutes.

5.     Return to system view.

quit

6.     Enter service template view.

wlan service-template service-template

7.     Bind an SQA profile to the service template.

sqa-profile profile-name

By default, no SQA profile is bound to a service template.

SQA configuration examples

Example: Configuring SIP-based SQA

Network configuration

As shown in Figure 1, the SIP server installed with third-party VoIP server software acts as both the SIP proxy server and SIP registrar to manage SIP UA registration and SIP calls. Client 1 and client 2 installed with third-party client software can place calls to each other.

Configure SIP-based SQA on the AC to optimize multimedia traffic of SIP calls for a service template to provide high-quality multimedia services.

Prerequisites

Assign IP addresses to interfaces, and make sure the devices can reach each other.

Make sure the AP can work correctly on the AC and clients can communicate with each other.

Procedure

1.     Configure the SIP server:

Install third-party VoIP server software, register UAs, and specify the usernames (phone numbers) and passwords for the clients. (Details not shown.)

2.     Configure client 1 and client 2:

Install third-party VoIP client software, specify the IP address of the SIP server, and configure the username (phone number), password, and other parameters on each PC. (Details not shown.)

3.     Configure the AC:

# Create an SQA profile, and enable SIP-based SQA.

<Sysname> system-view

[Sysname] sqa profile 1

[Sysname-sqa-profile-1] sip enable

[Sysname-sqa-profile-1] quit

# Bind an SQA profile to a service template.

[Sysname] wlan service-template service

[Sysname-wlan-st-service] sqa-profile 1

[Sysname-wlan-st-service] quit

[Sysname] quit
