FTTC Vs FTTP latency (Openreach network)


[link to this post] 		 
Hello,
I'm wondering how much of an improvement would FTTP have on ping (via BT 21CN/Openreach network) compared to having FTTC with an provider that uses BT 21CN/Openreach or TalkTalks Backhaul.

I'm currently getting 10-11ms to most servers located in London Docklands (TalkTalk FTTC) from Bristol (1.2km away from the cabinet) so I guess I'll be pulling around 7-9ms when I switch to FTTP next month.

Thanks,

My ping reduced by about 3ms when I moved from PlusNet FTTC to Cerberus FTTP. Pings to bbc.co.uk:

Plusnet round-trip min/avg/max/stddev = 5.232/5.648/6.707/0.390 ms

Cerberus round-trip min/avg/max/stddev = 2.525/2.811/2.984/0.134 ms

I am on FTTP with BT and I am about 5.43km (3.37miles) (as the crow fly's) from Telehouse Data Centre so my pings are normally low, Not to sure what servers you are checking with, but I here are the ones I just pinged just now:

[re: Jake4] [link to this post] 		 
My latency (when pinging google.co.uk) went from 22ms to 20ms when I switched from TalkTalk Business FTTC to Fluidone FTTP, with the latter on BT Wholesale tails. So I wouldn't expect a huge improvement in latency, main factors are your geographical location and the route your FTTC/P line takes to London, as that's where most ISPs have their data centres. I'm in the Highlands.

On FTTC I was getting around an additional 2 milliseconds, with another good ISP of course.

I still have both PlusNet FTTC (about 30M down/4M up) and Cerberus FTTP.

To 8.8.8.8 via Cerberus FTTP:

round-trip min/avg/max/stddev = 4.976/5.048/5.163/0.082 ms

To 8.8.8.8 via Plusnet FTTC:

round-trip min/avg/max/stddev = 10.178/10.425/11.073/0.343 ms

You're welcome smile

In the two examples I give, the tiny difference in latency between FTTC and FTTP seems to be due to the difference in the connection speeds.

In the two examples I give, the tiny difference in latency between FTTC and FTTP seems to be due to the difference in the connection speeds.

I was going to say something like that, one of my neighbours also on FTTP at the start took the 80Mbit package and I did notice their latency was a fair bit larger than mine, but when they upped to the Ultrafast 1 speeds (cannot remember the speeds) it started to be closer to my latency.

I would of expected it between FTTC and FTTP, but these were both on FTTP, so maybe the way they cap the speed affects the latency.

So you might have something there.
