This voice traffic flow using Lumen® 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. (We also offer a use case for web traffic.) These three steps need to be done to make a complete configuration: SLA profiles, forwarding profiles, policies and rules:
Note: The Lumen 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.
The configuration is made on a branch template and not on an individual appliance.
A service level agreement (SLA) defines the network performance parameters between your organization and CenturyLink and includes packet delay, packet loss, and jitter 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.
An SD-WAN policy called the Default-Policy will have already been created.
The last step is to apply these changes to your branches.
