Re: [AusNOG] NBN FTTN TC2 Services WA North West

2018-06-13 Thread Paul Brooks 
TC2 and TC1 can be very sensitive to arguably overzealous policing, requiring 
tight
shaping at the NNI (POI) and attention to Ethernet buffering, burst limits and
inter-packet gaps or packets will be dropped.
Usually voice traffic on TC1 doesn't tickle the policing  though as the VoIP 
CODEC
naturally leaves good spaces between the packets. Data packets at TC2 different 
story.
Check packet-loss during the throughput tests, in each direction independently 
if you
can - overzealous inbound policing or inadequate outbound shaping will result in
packets being tossed due to micro-spikes in traffic, even when the long-term 
average
should be below the policing threshold - and that might be between your 
upstream and
the NBN kit at the POI, than between you and your upstream network.

Hi Brad

Sounds similar to our issue. I’ve sent umpteen graphs and iPerf results to 
Vocus.

Can I ask what the latency is on those links for you? Vocus are telling us it’s 
the latency at ~45ms that is causing the issues. Various throughput calculators 
are giving me anywhere between 8-9.5Mbps of bandwidth, yet we seem to be only 
able to achieve around half.

Cheers

David.

Hi David,

I had a similar problem in the Wollongong area. We connected up the first TC2 
in that area and when we tested the service, we never got the order speed. I 
logged a fault with OPTUS and sent them traffic graphs and test results. A day 
or two later they fixed the issue, they hadn't provisioned or ordered the back 
haul correctly.

Hi Folks

Is anyone else running NBN TC2 only services? Having issues with services 
running in the North West that are all backhauled to the Geraldton POI.

Latency doesn’t seem extreme for the distance, usually ~45ms, but on say a 10Mb 
TC2 service, we’re only achieving ~5.5Mbps. FTTN services connected to other WA 
POIs, tops ~18ms, but seem to run OK.

Any ideas?

Cheers

David.
