Such pings are useful for:

  • Discovering how sizes affect latencies
  • Discovering packet reassembly issues
  • With no-fragment set, discovering faults in MTU detection
  • On wireless networks:
    • Discover the effect of packet size on fragmentation settings
    • Providing a consistent source of traffic to do RF analysis
