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

Packets In: The number of return packets received from the target host. To be considered “on time,” return packets are expected back before the next packet in the sequence of Ping packets is sent. A count of the number of late packets appears in parentheses to the right of the Packets In count.

In the example that follows, a Netopia R9100 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 R9100 before the third Ping packet is sent. The first and third return Ping packets are on time.
