Packets Out: The number of packets sent by the Ping test.

In the example that follows, a Netopia R7200 is sending Ping packets to another host, which responds with return Ping packets. Note that the second return Ping packet is considered to be late because it is not received by the Netopia R7200 before the third Ping packet is sent. The first and third return Ping packets are on time.
