BWPing is a tool to measure bandwidth and response times between two hosts using Internet Control Message Protocol (ICMP) echo request/echo reply mechanism. It does not require any special software on the remote host. The only requirement is the ability to respond on ICMP echo request messages. Although BWPing does not require any special software on the remote host (only the ability to respond on ICMP echo request messages), there are some special requirements to network infrastructure, local and remote host performance:
If some of these requirements are not satisfied then the measurement results will be inadequate or fail completely. In general, for testing bandwidth where QoS is implemented, always test with traffic that matches the QoS class to be tested.
