[AusNOG] the state of bufferbloat awareness and remediation in australia?

[Damien Gardner Jnr]

Had started replying the other day, but seems I forgot to hit send, so i’ll
reply tothis one instead :)

We see them as PPPOE headers, on our AAPT wholesale services with NBN and
AAPT direct DSL services - but not on Telstra services.   It’s very handy,
as AAPT at least rate limit how often you can do a line state diagnosis to
pull sync rates from NBNco (it’s about six or seven per 30 mins maximum),
so if you have a tech at the customer’s premises messing with cabling,
being able to see sync rates on every reconnection saves a lot of hair
pulling once you hit the rate limit for LSD’s.
