Hi LiQuidAce. Like me, it's all hops beyond your router. This may be Telecom doing Traffic management and not Xnet.

There was mention on geekzone (can't find the post now) that Telecom Wholesale had given ISPs notice that they were planning on implementing "Dimensioning" on their ethernet backhaul (UBA). like they do on the old ATM backhaul (UBS). I believe it's been open pipes on the Next Generation Network cabinets and ADSL2+ exchange upgrades up to now. If they have implemented this it may explain why evening latencies have increased? 15 minute average of 45kbps per connected customer + allowance for 3 months growth & latency less than 1000ms is all Wholesale have to provide I believe.

Regards Allen



UBA over an Ethernet handover has had a dimention on it for ages now. I believe Xnet may have already moved all their users over to EUBA0 however. I believe there were and are still plans to place a user dimention on EUBA0 later this year as per the last Telecom/Chorus update.

It's going to suck for some ISPs as an employee of another ISP posted here that their backhaul usage increased five fold when first moving from UBA to EUBA.

Hi Cameron.

Any progress on this issue?

15 minute plot from 19:45. 5 second pings. Seeing 2% to 3% packet loss as well on this and ping gadget. (Ping monitor trace is aprox 10 minutes of 5 second pings)

 





Regards Allen.

Hi Allen, 

Still working to resolve this issue, at this point it appears to be directly related to backhaul dimensioning from the Telecom Wholesale network to our own.

That anomaly you see above where latency was great relates to an outage which caused a number of users to drop offline at peak time.  This freed up backhaul and restored the great pings, until everyone got back online. 

Will update you when I have more info.

Thanks
Cameron

Hmm, IPv6 seems to be down today, too.

Ran this by Operations who were unable to confirm any IPv6 problem and confirm they see other trial users on it.

Hmm, I wonder if this is an issue with the 877.. I seem to have this issue a bunch, where v6 doesn't come back up after a disconnect/ipv4 change.. I'll have a look at this later.

Just wondering how latency is going at peak times?

I've been trying to diagnose an intermittent fault with my PC. Havn't been too attentive of late. From memory last night it was still a little spikey, up from 45 to 80ms or so over peak? Just looked now, and flat at 46ms

I'll keep an eye on it tomorrow and report back.

Regards Allen.

Latency is pretty much flat at 45ms when PC is idling even over peak evening period now.
I have also now been upgraded to ADSL2+ which will have helped.
