FTTC Latency


[link to this post]
 
Hello!

I'm moving house and FTTC is supposed to be enabled at the new exchange in just a few weeks. Latency and jitter is very very important to me - I'm currently with Be and have fastpath enabled and ping bbc at 6-7ms. I've also only ever been with Be (aside from some sad sad months with Sky LLU) since moving to the UK in 2007 (from Aus) so don't have any familiarity with BT etc. and the dreaded (?) DLM.

As far as I can tell, there's no option to remove interleaving on FTTC at the moment - does interleaving even apply? Does anyone know of any plans for BT to offer this? What sort of first hop latencies are people generally getting? A tracert to wargamez.dk (for routing as well as first hop latencies) would be great!

cheers!

Interleaving does apply to FTTC/VDSL2 and the level of interleaving will change dependant upon what the DLM deems necessary.

At the moment* here is my traceroute to wargamez.dk -

wargamerz.dk

* - I say at the moment as DLM seems to change the level of interleaving on my line on a weekly basis. Pings have been as low as 9ms some weeks.
