Why
Mobile apps, conferencing, industrial remote control, cross-region systems and cloud services often fail only in the field. Causes combine delay, jitter, burst loss, bandwidth reductions, micro-outages, DNS/TLS variations and application retries, rather than one fixed delay or loss value.
Guessing fixed delay or random loss may reproduce the wrong scenario. Record quality with BestPerf, retain abnormal sessions with Flow Hunter and apply measured impairments with ChaosBridge. Where needed, replay field PCAPs with NetAccura Traffic Generation to reproduce from evidence.
Topology
How
Run BestPerf at the customer site or remote node to record RTT, loss, jitter, micro-outages, throughput and directional differences around the issue. For application-specific problems, capture key sessions and PCAP extracts through Flow Hunter on a mirrored port.
Convert field data into baseline/peak RTT, jitter distributions, burst-loss lengths, bandwidth caps, reordering probabilities and outage windows. Preserve PCAP samples for protocol-related issues.
Install ChaosBridge between client and server and apply the measured profile. For traffic-driven issues, replay field PCAPs with NetAccura Traffic Generation to reproduce the same input. Keep real clients and servers for login, handshake and application-response tests.
Retest application or policy fixes under the same impairment scenario. Include success rates, response times, retries, timeouts and session evidence in regression reports, then add stable scenarios to CI.
Product Stack
Core Emulation Equipment
Optional Supporting Tools
BestPerf
Actively measure RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load to establish link baselines.
Flow Hunter
Capture passively through mirrored ports or TAPs for L2-L7 analysis, session investigation, protocol-stage diagnosis and PCAP export.
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
Repeatedly trigger, observe and fix issues in a controlled environment instead of relying on remote customer-site troubleshooting.
Use identical quality profiles and samples before and after a fix to show whether the issue is resolved and experience improves.
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.
