Capabilities
Built for Performance
VPP/DPDK Data Plane
Vector Packet Processing with DPDK delivers wire-speed forwarding on commodity NICs. Scales linearly with CPU cores — add cores, get more throughput.
Commodity x86 Hardware
Runs on any x86 server with DPDK-compatible NICs. No proprietary hardware, no vendor lock-in. Deploy on Dell, HPE, Supermicro, or whitebox.
CGNAT with BTRC Logging
Inline NAT44 with deterministic mapping and BTRC-compliant session logging. Full audit trail for regulatory compliance.
Real-time Telemetry
Per-subscriber traffic counters, session monitoring, and QoS policy enforcement. Integrated with Prometheus and Grafana dashboards.
