Detect Network Issues Earlier

Network operations teams need to detect service-affecting problems early enough to isolate and resolve them before subscribers are impacted. That requires an end-to-end view of network performance: correlating key performance indicators (KPIs) from multiple locations and domains to determine whether a condition is local or part of a wider event, then confirming the issue, locating the affected segment, and identifying root cause. For recurring problems, engineers want to capture the KPI patterns that precede an outage and reuse them for automated detection.

In many service providers, teams are organized by network segment and rely on point tools that provide narrow, localized views and cannot correlate data across the network. Engineers analyze only their own domain, missing relationships between issues in different areas, so system-wide problems go undetected until they escalate into outages. Resolution then requires large war-room efforts involving dozens of engineers. Reduced headcount and competing priorities, such as deploying 5G while maintaining 4G, leave little capacity for manual monitoring and investigation. Teams need correlated, actionable alerts instead of raw metrics and faults, plus a way to automate detection of known failure conditions.

Early Network Detection Solution

The Keysight VisionWorks Service Assurance Platform provides end-to-end active testing and correlates data from multiple network locations and sources to isolate problems quickly. Instead of raw metrics and faults, VisionWorks delivers actionable alerts: it tests the end-to-end network, confirms the problem, drills down to the exact location and cause, and includes recommended next steps. Working with Keysight experts, teams identify the KPIs that signal their most common problems and build advanced KPIs and signatures that automate detection, testing, and reporting. Intelligent alarms track multiple concurrent variables across network segments. At a Tier 1 operator, VisionWorks was among the first systems to detect a multiday nationwide outage and revealed KPI indicators roughly eight hours before subscriber impact. Signatures built from those indicators now let a few engineers resolve issues that previously required as many as 60.
