Latency is not really any different to FTTC on fastpath, right?
I answered that exact question from you back in February
As for FTTP, I obviously can't comment though all reports so far are the latency should be identical to FTTC at the same ISP.
I said that the difference was usually around 1-3ms (with the same ISP and same routing) and that the difference on my line was 2.1ms
You said that was margin of error.
There's a definite drop in latency. As Carl says it's about 2-3ms.
My BT FTTC ping was 16ms.
My BT FTTP ping is just under 14ms.
Those numbers are very consistent between PPP sessions, unlike some other ISP's that can vary a lot between different sessions/gateways.
How are you working out the latency to the exchange?
I'd love to know this also.
I'm guessing it's either something displayed in the ONT, or Carls somehow pinging the OLT or Nokia 7750 in his exchange?
