network performance measurement using Iperf
- 1. Network performance measurement using IPERF By Shravankumar Kiran Bhat 1
- 2. Measurement of parameters of network Bandwidth Latency Error Rate Jitter 2
- 3. IPERF is tool for measurement of the maximum achievable bandwidth for IP networks 3
- 4. Why Iperf ? No manual data input Multiple parallel streams 4
- 5. How it works ? SERVER iperf -s CLIENT iperf -c <SERVER_IP> 5 data
- 6. Server 6
- 7. Client 7
- 8. Options 8
- 9. Server 9 -i set interval between reports
- 10. 10 -i set interval between reports Client
- 11. 11 Server -u Perform a UDP test
- 12. 12 Client -u Perform a UDP test
- 13. 13 Client -b Set target bandwidth
- 14. 14 Server -b Set target bandwidth
- 15. 15 -t Time in seconds to transmit data Client
- 16. 16 Server -t Time in seconds to transmit data
- 17. 17 Client -n Bytes to transmit
- 18. 18 Server -n Bytes to transmit
- 19. 19 Client -w Set window size
- 20. 20 Server -w Set window size
- 21. 21 -m display maximum segment size Client
- 22. 22 -m display maximum segment size Server
- 23. 23 -P Number of parallel streams Client
- 24. 24 -P Number of parallel streams Server
- 25. 25 Client -F Data as an input file
- 26. 26 Server -F Data as an input file
- 27. 27 Client -f Format of output
- 28. 28 Different formats which can be used K - Kilobytes M - Megabytes G - Gigabytes k - Kilobits m - Megabits g - Gigabits
- 29. 29 Server -f Format of output
- 30. 30 Client -p Port to use
- 31. 31 Server -p Port to use
- 32. 32 Client -l Specify datagram size
- 33. 33 Server -l Specify datagram size
- 34. 34 Client -r Bidirectional individual bandwidth measurement
- 35. 35 Server -r Bidirectional individual bandwidth measurement
- 36. Tired of commands ? 36 Use Jperf !
