I feel sorry for ping. Ping has been beaten up, abused, misunderstood, banned and even tossed aside.
Ping was originally used to check if a device was up or down, period. Back in the day, equipment failure was very common. I chuckle thinking back at those sales people that used Mean Time Between Failure to sell their equipment. As network analysts, we needed a way to see if our hardware or equipment failed and ping did the trick.
Over the years, SNMP was introduced to aid in network visibility, but we still used ping for simple up and down checks. In the 90s, bandwidth limits were becoming an issue, so we used ping response time results to determine if a device or link was slowing us down.
