Network architecture explorer

Click an NF and learn what it does, who it talks to and how it fails.

• AMF — responsibilities, N1/N2/N8/N12/N22, KPIs and failure scenarios.
• SMF — PFCP control, session control, QoS management.
• UPF — packet forwarding, QoS enforcement, traffic steering, charging.
• AUSF, UDM, PCF, NSSF, UDR, NRF — all included.

Network slicing simulator

See slice selection happen and watch resources allocate.

• Real-time CPU, memory, bandwidth and UPF resource allocation visuals.

QoS & bearer management

4G bearers and 5G QoS flows — visualized end-to-end.

• LTE default bearer and dedicated bearer flows.
• 5G QoS Flow with QFI, 5QI, ARP, GBR, MBR shown per flow.
• Mapping between QoS flows and DRBs on the radio interface.

Internet access simulation

Follow a packet from the UE to the public Internet — and back.

• IP allocation (IPv4, IPv6, dual-stack).
• NAT, DNS, routing visualizations.
• End-to-end traffic flow with hop-by-hop annotations.

Resource management simulator

Move the sliders. Watch the load recalculate.

• Inputs: subscribers, average throughput, sessions per subscriber.
• Outputs: AMF / SMF load, UPF throughput, slice utilization charts.
• Compare scenarios side-by-side to plan capacity.

Fault & troubleshooting simulator

Break the network on purpose. Learn how it recovers.

• AUSF failure → Registration Failure path highlighted.
• UPF failure → loss of Internet connectivity for affected sessions.
• NSSF failure → Slice Selection Failure with root-cause analysis.
• Configurable fault types: down, overload, packet loss, latency injection.

Learning Management System

Structured paths with embedded procedures, videos and labs.

• Courses → modules → lessons hierarchy.
• Lessons embed procedures, scenarios and PDFs natively.
• Progress tracking and resume-where-you-left-off.
• Course-completion certificates with public verification URL.

Quiz & assessment engine

Tests that actually probe understanding.

• Multiple choice with explanations on every answer.
• Drag-and-drop placement of messages and parameters.
• Match network functions to their responsibilities.
• Sequence messages in the correct order to pass.

Cross-corpus search

Find anything in seconds.

• Search across messages, procedures, protocols and network functions.
• Examples: "Registration Accept", "PFCP Session Establishment", "S-NSSAI".
• Facets by category, plan, difficulty and protocol.

Download center

Take procedures with you — share with colleagues or print for training.

• Export procedures to PDF, PNG, SVG or PowerPoint.
• Export certificates to PDF for HR submission.
• Download history with re-generation on demand.

AI telecom assistant

Ask a question. Get an answer grounded in the platform's own corpus.

• "Why did the Registration Reject occur?"
• "Explain PFCP Session Establishment."
• "Show the AMF → SMF interaction during PDU Session setup."
