AT&T SD-WAN uses software-defined path selection and dynamic routing to define the most optimal connection between two locations.
If a circuit fails, there are already multiple paths in place to establish full coverage. Traditionally, businesses have had to keep standby circuits off line in case the network went down, but
AT&T SD-WAN makes all available circuits in production at all times, using intelligent routing to find the optimal path for every traffic load at any time. If a circuit is unavailable or taken offline, preset policies powered by rules-based automation will reroute traffic to the next available circuit to maintain business continuity. This provides backup for when circuits fail while optimizing network resources in production.
AT&T SD-WAN also enhances security, making it less likely that malicious intent is able to disrupt operations. Pre-defined security policies are applied holistically across the network based on rules, and users can drill down to roll out security services such as web filtering and malware protection to individual locations, users, or traffic types.
