This voice traffic flow using CenturyLink® SD-WAN use case shows the steps you need to take to complete a rule for a voice traffic flow based on network service level agreement (SLA) parameters such as latency, jitter, and packet loss on the WAN connectivity of your branch location. These three steps need to be done to make a complete configuration: SLA profiles, forwarding profiles, policies and rules:
Note: The CenturyLink engineer may have already defined some standard SLA profiles and forwarding profiles. In this case, you will see them and can add a new rule that refers to those profiles.
Creating a voice traffic SLA profile
The configuration is made on a branch template and not on an individual appliance. Read an overview to compare the Director Context and Appliance Context.
Step 1—configuring SD-WAN SLA profiles
A service level agreement (SLA) defines the network performance parameters between your organization and CenturyLink and includes packet delay, packet loss, and jitter profiles.
Step 2—configuring SD-WAN forwarding profiles
A forwarding profile determines the traffic path based on realtime SLA performance of traffic. A forwarding profile defines the properties such as load balancing method, priority of circuits, circuit type, circuit media, and others to be selected for traffic.
Step 3—configuring SD-WAN policies and rules
A SD-WAN policy called the Default-Policy will have already been created.
The last step is to apply these changes to your branches.
