# Stream Processing for Telecom Networks at Scale

Billions of network events per second. Millions of subscribers generating data simultaneously. Ververica processes it all at 6.9B records/sec with sub-10ms latency.

## Key Reasons To choose Ververica

Why Ververica

Every cell tower, every base station, every subscriber device generates continuous telemetry. Legacy systems collapse under the load. Sampling data means missing problems.

Edge computing, IoT devices, and network slicing multiply event volumes by orders of magnitude. Infrastructure built for 4G workloads cannot keep pace with 5G reality.

By the time batch analytics identifies a dissatisfied subscriber, they have already ported their number. Retention campaigns that arrive 48 hours late are campaigns that fail.

SIM swaps, subscription fraud, and international revenue share fraud execute in minutes. Daily fraud reports are post-mortems, not prevention.

## Telecom networks generate data at machine speed. Processing it on human timelines is not an option.

Use Cases

### Network Monitoring

Process CDRs, performance counters, and alarm data from every network element in real time. Detect degradation the moment it begins. Correlate events across radio, transport, and core layers in a single stream.

### Predictive Maintenance

Analyze equipment telemetry patterns to identify hardware failures before they cause outages. Schedule maintenance during low-traffic windows. Reduce mean time to repair by acting on predictions, not incidents.

### Churn Prevention

Score subscriber behavior in real time. Detect dissatisfaction signals from call drops, billing disputes, and usage pattern changes as they occur. Trigger retention actions within minutes, not days.

### Revenue Assurance

Reconcile CDRs, billing records, and interconnect data in real time. Detect revenue leakage the moment records diverge. Close the gap between service delivery and accurate billing.

### Fraud Detection

Score every SIM activation, international call, and data session against fraud patterns in sub-10ms. Block fraudulent activity before it generates cost. Eliminate the delay between fraud execution and detection.

### 5G Edge Processing

Process data at the network edge with low-latency streaming pipelines. Support network slicing, MEC applications, and IoT device management with real-time event processing where the data originates.

## Performance at Telecom Scale

### 6.9B Records/Sec

VERA engine throughput. CDRs, network events, and subscriber data processed without sampling or dropping events.

### Sub-10ms Latency

From network event to action. Fraud detection, alarm correlation, and subscriber scoring at wire speed.

### 2x Faster

Double the throughput of standard Apache Flink. Process 5G data volumes on infrastructure sized for 4G budgets.

### 40% Lower TCO

Measured total cost of ownership reduction. Fewer servers processing more data. Operations costs cut proportionally.

## Frequently Asked Questions

### Can Ververica process the data volumes generated by 5G networks?

Yes. VERA engine processes 6.9B records per second. That capacity covers CDRs, IoT telemetry, network performance counters, and subscriber events from 5G networks simultaneously without sampling or data loss.

### How does real-time fraud detection work for telecom?

Every event, including SIM activations, international calls, and data sessions, is scored against fraud models in sub-10ms. The system applies rules and ML models to detect patterns like SIM swap fraud and Wangiri attacks before they generate financial loss.

### Does Ververica integrate with existing BSS/OSS systems?

The platform connects to mediation platforms, billing systems, CRM, and network management tools through pre-built connectors and standard APIs. CDC connectors capture changes from existing databases without modifying source systems.

### What deployment options exist for telecom operators with data sovereignty requirements?

Ververica offers BYOC and self-managed deployment. Both keep all data within your own infrastructure. No subscriber data, CDRs, or network telemetry leaves your environment. SOC 2 Type II and ISO 27001 certified.

### How does the platform support network alarm correlation?

Ververica processes alarm streams from radio, transport, and core network layers in a single pipeline. It correlates related alarms, suppresses noise, and identifies root causes in real time, reducing alert volume by up to 90%.
