Service assurance is the part of the operations support system (OSS) responsible for keeping services working once they are live. It detects faults, measures performance against targets, and gives operations teams the evidence they need to fix problems before customers notice them.
What This Coverage Includes
We report on fault management, which collects and correlates alarms from network equipment; performance management, which tracks capacity and quality counters over time; and network probes and test systems, which observe live traffic or generate test traffic to measure what subscribers actually experience. This hub also covers quality of service (QoS) and quality of experience (QoE) analytics, service level agreement (SLA) management for enterprise customers, and field test tools used by network technicians.
Why It Matters to Operators
As networks move to virtualized and cloud-native functions, the number of components that can fail has grown while the tolerance for outages has shrunk. Assurance vendors increasingly apply analytics and AI to separate the alarms that matter from the noise, and closed-loop automation is turning assurance from a monitoring function into a control function.
