September 14, 2021

To optimize QUIC ABR video traffic over UDP, begin by enabling the video optimization feature. After you complete the configuration, the appliance detects QUIC based ABR video traffic and applies the optimization bit rate that is configured on the appliance.

Configuring video optimization for QUIC by using the CLI

To configure video optimization for QUIC video traffic over UDP, you must perform the following tasks:

  1. Enable Video Optimization.
  2. Create a QUIC service.
  3. Create a QUIC load balancing virtual server.
  4. Bind QUIC web service to the loading balancing virtual server.
  5. Create video optimization policy for pacing QUIC based UDP traffic.
  6. Bind optimization policy to a QUIC based load balancing virtual server.

Enabling video optimization for QUIC traffic

If you want the Citrix ADC appliance to detect, optimize, and report video traffic, you must enable the Video Optimization feature and set optimization ON.

Note

If you want to use video optimization for QUIC traffic, you must enable the load balancing and AppFlow features.

To enable the video optimization

At the command prompt, type the following command:

enable ns feature VideoOptimization
<!--NeedCopy-->

Creating a service for QUIC traffic

A Citrix ADC appliance uses a QUIC service for the load balancing virtual server to connect to the egress router in the static routing mode.

Note

Currently, dynamic routing is not supported.

To create a load balancing web service for QUIC video traffic

At the command prompt, type:

add service <name> <router-IP> <serviceType> <port> -usip yes -useproxyport  [yes | no]
<!--NeedCopy-->

Example:

add service svc-quic 10.102.29.200 QUIC 443 –usip yes –useproxyport no

where IP address is the internet router address.
<!--NeedCopy-->

Creating a load balancing virtual server for QUIC traffic

A Citrix ADC appliance uses a load balancing virtual server for detecting and optimizing QUIC video traffic over UDP.

To create a load balancing virtual server for QUIC video traffic

At the command prompt, type:

add lb vserver <name> <serviceType> <ip> <port> -m MAC
<!--NeedCopy-->

Example:

add lb vserver vs-quic QUIC * 443 -persistenceType NONE -m MAC -cltTimeout 120
<!--NeedCopy-->

Binding a QUIC web service to the load balancing virtual server

After you have created the web services and load balancing virtual server for QUIC traffic, you must bind the services to the virtual server.

To bind a web service to load balancing virtual server for QUIC video traffic

At the command prompt, type:

bind lb vserver <name> <serviceName>
<!--NeedCopy-->

Example:

bind lb vserver vs-quic svc-quic
<!--NeedCopy-->

Creating Video Optimization Policy for QUIC based UDP traffic

To optimize QUIC based UDP traffic, you have to configure optimization pacing policies and its actions. You must then, bind the policies to QUIC based load balancing virtual servers. For each policy, create an action first so that you can associate it to the policy.

To add an optimization action

At the command prompt, type:

add videooptimization pacingaction <action Name> -rate <integer> [-comment <string>]
<!--NeedCopy-->

Where, the rate parameter specifies the rate in Kbps at which to send the traffic (the pacing rate).

Example:

set videooptimization parameter -QUICPacingRate 1000
<!--NeedCopy-->

where 1000 represents the desired pacing rate in Kbits/sec.

To add an optimization policy

At the command prompt, type:

add videooptimization pacingpolicy <name> -rule <expression> -action <string>
<!--NeedCopy-->

Example:

add videooptimization pacingpolicy myOptPolicy2000 -rule TRUE -action MyOptAct2000
<!--NeedCopy-->

Binding Optimization Policies to a QUIC Load Balancing Virtual Server

To optimize QUIC video traffic over a UDP connection, you must bind the optimization policies to a QUIC load balancing virtual server.

To bind an optimization policy to a QUIC Load Balancing virtual server

At the command prompt, type the following command:

bind lb vserver <name> -policyName <policy_name> -priority <positive_integer> -type (REQUEST)
<!--NeedCopy-->

Note

The pacing policies must be bound to a QUIC load balancing virtual server only at request time.

Example:

bind lb vserver vs-quic -policyName myOptPolicy2000 -priority 3400 -type  REQUEST
<!--NeedCopy-->
