When service providers send voice and video applications over next-generation IP networks, end-to-end service assurance becomes their most important concern. While traditional approaches to providing service assurance work well for high-speed data, they fail to address many of the network conditions that affect video and voice services. These problems may be caused by transient failures, misconfigurations, or even design violations.

Circadence® takes a new approach called service fidelity. Derived from real-time, highly accurate views of the network and applications, service fidelity relies on the ability to detect and remediate issues that are invisible to traditional service assurance and network management systems. This paper discusses Circadence’s approach to, and rational for, service fidelity – the next level of IP service assurance.
