Why
Requirements
3GPP NTN includes satellites, HAPS and UAS. GEO, MEO and LEO differ in altitude, propagation delay, moving beams, Doppler variation, handovers and coverage continuity, all of which affect services.
Test terminals, ground stations, emergency communications and remote sites beyond ideal LAN conditions. Emulate high RTT, jitter, burst loss, reduced bandwidth, handover outages and concurrent services to validate voice, video, telemetry, control and synchronization.

How
Implementation
2
Build the Lab Link
Insert ChaosBridge between terminals, gateways, ground-station simulators or application servers and apply satellite profiles to real traffic.
3
Measure QoS and Session Quality
BestPerf measures RTT, loss, jitter and throughput continuously. Flow Hunter analyzes failures and retransmissions in voice, video, telemetry and HTTP/TLS sessions.
4
Add Multi-Service Load
Generate background telemetry, backhaul and concurrent streams to check QoS during bandwidth reductions and competing traffic.

Network Quality Measurement Software
BestPerf
Actively measure RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load to establish link baselines.
Network Traffic Analyzer
Flow Hunter
Capture passively through mirrored ports or TAPs for L2-L7 analysis, session investigation, protocol-stage diagnosis and PCAP export.
NetAccura Traffic Generation
NetAccura Traffic Generation
Generate L2-L3 test streams. Software models also replay Ethernet PCAPs, rewrite IPv4 addresses and TCP/UDP ports, and multiply traffic for performance, security detection and issue reproduction. Stop all transmit tasks before switching modes. Simultaneous generation and replay require separate devices.
Result
Expected Outcomes
Rehearse Satellite Services before Deployment
Expose terminals, gateways, applications and QoS policies to delay, handovers and loss to find timeout, buffer, retransmission and bitrate adaptation problems early.
Compare Orbits and Scenarios Consistently
Use the same metrics across LEO, MEO, GEO, emergency, maritime, aviation and remote-site scenarios.
Produce Reviewable Reports and Evidence
Deliver more than throughput or delay figures: include topology, parameters, timelines, quality curves, key sessions, anomalies, PCAP extracts and retest results. Development, testing, operations, vendors and customers can discuss the same evidence rather than relying on screenshots, verbal descriptions and repeated debate.
