This web traffic flow using Lumen® SD-WAN use case shows the steps necessary to complete a rule for web 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 voice traffic.)
These three steps need to be done to make a complete configuration: SLA profiles, forwarding profiles, policies and rules:
- SLA profiles—set up the network performance parameters that monitor the performance of access circuits and WAN links of your related branch locations. An access circuit or WAN link is selected based on the threshold values specified in the SLA profile.
- Forwarding profiles—defines the properties of WAN circuits to be selected for traffic. It defines properties such as the load balancing method for traffic, priority of circuits, circuit type (broadband or MPLS), circuit media, and other associated attributes. Forwarding profiles are associated with SLA profiles to determine the selection of WAN circuits in a given order of priority.
- Policies and rules—you can configure traffic based on matching criteria such as the traffic source address, destination address, source zone, and specific IP packet header information.
