It is widely believed that, on its own, ICMP echo (ping) provides no information regarding the bandwidth. ICMP echo normally only provides information regarding latency. ICMP bandwidth tools derive bandwidth measurement by comparing latencies for small and large pings. These implementations are based on the research on active throughput estimation using RTT of differing ICMP packet sizes as well as estimation of the available bandwidth ratio of a remote link or path segments research Advantages Unlike traditional methods for measuring bandwidth such as iperf, ICMP bandwidth bandwidth tools do not require a specialized server component running on the remote machine as many internet hosts readily respond to pings. These tools can measure bandwidth to internet gateways and non-web-capable servers. Often this can be more useful for troubleshooting purposes. Disadvantages Firewall, QoS and fragmentation can lead to unexpected results. Depending on implementation, some tools can't work reliably with ping sizes > 1500 while others depend on ping sizes > 1500. Bandwidth measurement usually does not work with large websites do not respond to pings or truncate replies due to DDoS concerns.
