Slide 3 of 30
Notes:
We have other tools (e.g. traceping, server response measurements) but will not talk about here, since either not ready, or there are no plans to distribute, or they are not for the WAN.
Some sites block ping (e.g. LANL scared of Ping O’ Death), but we choose clients so usually not a problem
Network impact is ~ 6bytes/sec per client monitored, plus ~ 0.06 bytes/sec per client for gathering data.Recommend sites identify hos to be pinged by providing and alias ping.site.domain
We would liketo recommend that sites identify the host be pinged by providing a DNS alias of the form ping.site.domain
