Guaranteed Performance Per Slice
CARAT delivers slice-aware performance control aligned to SLA, QoS, and RAN behavior—ensuring your network slices consistently meet their commitments
The Network Slicing Challenge
5G Slicing Promises Differentiated Services—But Delivering Them Is Complex
Network slicing enables operators to offer guaranteed performance levels for different services: ultra-reliable low-latency for industrial automation, high-bandwidth for video streaming, massive connectivity for IoT. But ensuring each slice consistently meets its SLA under real-world conditions—varying RF quality, congestion, mobility—requires sophisticated RAN-level optimization that traditional tools cannot provide.

How CARAT Optimizes Network Slices
Continuous monitoring, intelligent analysis, and automated action
Data Collection & Integration
CARAT ingests comprehensive data from your network: RAN counters, per-UE statistics, QoS metrics, transport performance, service-level KPIs, and configuration data. This multi-domain visibility enables accurate slice performance assessment.
Slice-Aware Analysis
AI-powered analysis compares actual performance against slice-specific targets (latency, throughput, reliability). The system identifies root causes: insufficient PRB allocation, poor RF conditions, scheduler misconfiguration, transport congestion, or capacity limitations.
Intelligent Prioritization
Probabilistic assessment determines which optimization actions will have greatest impact. The data correlation and prioritization agent schedules interventions based on urgency, business priority, and resource availability.
Automated Optimization
Within one operational day, CARAT executes optimizations: adjusting scheduler policies, modifying PRB reservations, tuning RF parameters, or recommending infrastructure changes. All actions maintain performance for other slices while improving the target slice.
Continuous Validation
The system monitors the impact of each optimization, validating that slice performance meets targets and adjusting further if needed. This closed-loop approach ensures sustained SLA compliance.
