Network Testing Skill

Comprehensive skill for network testing, benchmarking, and performance validation across all network layers.

Capabilities

• Bandwidth Testing: Run iperf3/netperf for throughput and bandwidth measurement
• Load Testing: Execute load tests with wrk, hey, k6, and Apache Bench
• Latency Analysis: Measure and analyze latency with ping, mtr, hping3, and traceroute
• Protocol Conformance: Conduct protocol conformance testing against specifications
• Chaos Engineering: Run chaos engineering network tests (packet loss, latency injection)
• Test Reporting: Generate comprehensive network test reports with metrics
• Performance Benchmarking: Benchmark network performance against baselines
• Connection Testing: Test connection establishment, teardown, and pooling

• netperf - Network performance testing
• wrk - HTTP benchmarking tool
• k6 - Modern load testing tool
• hey - HTTP load generator
• tc - Traffic control for network shaping
• mtr - Network diagnostic tool
• hping3 - TCP/IP packet assembler

Target Processes

• network-testing-framework.js
• load-testing-tool.js
• protocol-fuzzer.js

Usage Examples

Bandwidth Testing

iperf3 -c server.example.com -t 30 -P 4
iperf3 -s -p 5201

HTTP Load Testing

wrk -t12 -c400 -d30s http://localhost:8080/
k6 run --vus 100 --duration 30s script.js
hey -n 10000 -c 100 http://localhost:8080/

Latency Analysis

mtr --report --report-cycles 100 example.com
hping3 -S -p 80 -c 100 example.com

Network Chaos

tc qdisc add dev eth0 root netem delay 100ms 10ms
tc qdisc add dev eth0 root netem loss 5%

Quality Gates

• Bandwidth meets requirements
• Latency within SLA thresholds
• Error rates below threshold
