Abstract

Problems are proactively analyzed and responded to as they are detected in a virtual private network (VPN) access path rather than waiting for a user to manually report the problem. When a problem is automatically detected, such as a failure causing degraded performance, an alarm may be generated. The alarm proactively triggers rules-based analysis procedures and isolation testing to diagnose problem in a VPN access path. Based on the testing and analysis, a comprehensive trouble ticket may be generated that is customized with specific alarm information allowing for increased efficiency in problem isolation and saving significant time and resources in resolving the problem.
