well, I selected two anchors placed in two different NAPs where all ISPs
in my scenario are present.
so, not a big concern if one anchor is down.

the other issue about possible bottlenecks is not applicable in that
context.

I like the idea and it should definitely be the way to go.

[atlas] Anchors as target hosts for SLA

2017-06-06 Thread Antonio Prado
hi,

do you think could be a good idea to use Ripe Atlas Anchors as target
hosts for measuring respect of SLA terms of an Internet transit?

SLA example

This Internet transit should meet the following criteria:

average round trip delay (echo request, echo reply) toward
$NEAREST_ATLAS_ANCHOR should be less than 100ms on a 10k packets stream
of pings; packet loss equal or less than 0.02%

pros, cons, recommendations?

thank you

hi,

who is a power user?
maybe an anchor host or an atlas sponsor?
