Software-defined wide area network self-service for service assurance

Abstract

The concepts and technologies disclosed herein are directed to software-defined wide-area network ('SD-WAN') self-service for service assurance. The proposed SD-WAN self-service solution can be used for any policy-driven system that automatically troubleshoots the problems resulting from hybrid SD-WAN network activities, including virtual private network (“VPN”), IP tunnel, IPSec, and security policies. According to one aspect disclosed herein, a method can check network configurations, analyze switch responses, and locate network problems quickly. Moreover, the method can test the functionality of a rules-based troubleshooting software effectively without employing expensive testing equipment and with minimal human intervention. Without the disclosed solution, telecommunications service providers may have to hire more software engineers who understand SDN and cloud technologies to effectively troubleshoot SD-WAN network connectivity issues, including issues caused by virtual network function (“VNF”), virtual machine (“VM”), and SDN switches. Thus, this labor-intensive solution is not only expensive, but also not immune to human error.
