Automated Root Cause and Service Impact Analysis

Enghouse Topology-Based Correlation provides automated root cause analysis with service and customer impact visibility using topology-based correlation techniques.

The solution integrates with the Enghouse Service Assurance database, which maintains physical and logical network topology. It can also integrate with existing network inventory systems or external resource databases to support dynamic topology models.

By correlating alarms with real network relationships, operations teams can quickly identify the true source of issues, understand downstream impact, and focus on events that matter most.

How it Works

null

Collect Network Events

Alarms and events are ingested from network elements and management systems.
null

Correlate Using Topology Models

Events are correlated against real-time physical and logical topology data.
null

Identify Root Cause and Impact

The system isolates the root cause and determines affected services and customers.

Use Case

Reducing Alarm Noise and Accelerating Root Cause Identification

Scenario: Operations teams managing large, multi-vendor networks struggle with alarm floods that obscure the real cause of service outages, leading to delayed resolution and customer dissatisfaction.

Solution with Topology-Based Correlation: By correlating alarms using real-time topology data, Enghouse Topology-Based Correlation filters out non-impacting events, identifies the true root cause, and highlights affected services and customers.

Results: Faster fault resolution, reduced alarm fatigue, and improved service reliability.

Technical Overview / Architecture

Topology-Based Correlation is built on Enghouse’s modular, standards-based OSS Service Assurance architecture.

Each module scales independently, allowing operators to deploy a complete pre-integrated stack or individual components as needed – without relying on monolithic system designs. The solution is optimized for highly complex, multi-protocol, multi-vendor networks.

Why Choose Topology-Based Correlation

Designed for complex, multi-domain networks

Native integration with Enghouse Service Assurance

Proven topology-based RCA techniques

Reduces alarm fatigue and MTTR

Scales independently as networks evolve

How We Help

Enghouse Networks helps operators simplify fault resolution by combining topology intelligence with real-time service assurance.

Our solutions improve visibility, reduce operational effort, and support reliable service delivery across evolving network environments.
