indicating the time of transmission and a sequence number, which are not found in this example. This allows ping to compute the round-trip time in a <a href="/wiki/Stateless_server" class="mw-redirect" title="Stateless server">stateless</a> manner without needing to record the time of transmission of each packet. </p><p>The payload may also include a <i>magic packet</i> for the <a href="/wiki/Wake-on-LAN" title="Wake-on-LAN">Wake-on-LAN</a> protocol, but the minimum payload, in that case, is longer than shown. The <i>Echo Request</i> typically does not receive any reply if the host was sleeping in hibernation state, but the host still wakes up from sleep state if its interface is configured to accept wakeup requests. If the host is already active and configured to allow replies to incoming ICMP <i>Echo Request</i> packets, the returned reply should include the same payload. This may be used to detect that the remote host was effectively woken up, by repeating a new request after some delay to allow the host to resume its network services. If the host was just sleeping in low power active state, a single request wakes up that host just enough to allow its <i>Echo Reply</i> service to reply instantly if that service was enabled. The host does not need to wake up all devices completely and may return to low-power mode after a short delay. Such configuration may be used to avoid a host to enter in hibernation state, with much longer wake-up delay, after some time passed in low power active mode.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
