Re: For enyone on Be* on fast path
 

What is 'fastpath'? Iam moving back to Basingstoke later this month, what kind of connection speeds do you get?

Thanks

Re: For enyone on Be* on fast path
 

interleaving delays the packets to reduce errors it can actually increase synch speed as a result and is generally more stable. The downside is it adds latency, fast path doesnt do this and as a result has faster latency.

The defaults as far as I know are like this.

Ukonline and sky adsl 1 fast path
All bt ipstream services fast path
BE and ukonline/sky adsl2+ interleaving

Re: For enyone on Be* on fast path
 

Nope... the Majority of ADSL cct's ive seen are interleaved by default.

Also Fastpath can on a stable line actually give faster sync speeds due to the error correction overheads are removed.

Re: For enyone on Be* on fast path
 

which isp are you seeing interleaving by default?

pretty much anyone on adslguide who has a ipstream based service is on fastpath unless the automated systems have changed them to interleaving for stability reasons. But I guess its possible some of the isps may be setting interleaving I think BT retail possibly I read actually. But thats just one isp. In truth interleaving is a way to hide actual problems on a line.

Interleaving alongside the error correction algorithm uses 576kbit of synch speed (on adsl1) but it increases the actual RCO (capacity) of the line as well, in my scenario I gain about 1300kbit RCO on interleaving takeing away the 576kbit I get about 700kbit net gain.

Might have been automated systems seeing as I tend to only look at faulty ADSL's ;)

On adsl2+ it can make a much bigger difference
For instance adsl 2+ Annex M 6db interleaved I sycned at 18Mbit down 2.3Mbit up

Adsl2+ Annex M 6Db Fastpath @ 22.8 Down ~2350 up (I think can't remember exactly what the upstream was)

Adsl2+ Annex M 3Db snrm @

Bandwidth (Up/Down) [kbps/kbps]: 2,589 / 24,514

Re: For enyone on Be* on fast path
 

yeah thats why I said I am not sure about adsl2+ as reports on adsl2+ defenitly seem to indicate fast path is a higher synch. Also the guys with adsl2+ typically have decent attenuation, when I said interleaving boosts synch speed I noticed its making little difference to strong tones but boosts the weaker tones so probably provides more of its boost to weaker lines.

I am on a LLU isp myself ukonline and I would love to go on adsl2 but I dont want interleaving and from what I read ukonline are anal about using fast path on adsl2. Although I expect an improvement on adsl2 it would be small on my line maybe just a few hundred kbit so I prefer to keep my super low latency.

Be seem to be quite good about setting the SNR margin on the DSLAM and interrupting DLM for you :)

They did mine for me the day after I joined :D

Re: For enyone on Be* on fast path
 

So this is really great for FPS etc games?

That last post Whooosh over my head!
So if I’m going with Be I ask for Fastpath

Re: For enyone on Be* on fast path
 

if you a gamer fastpath may be better but not always.

If fast path is stable its better.
If its unstable then it will be worse because you will have packet loss which is worse then haveing steady higher pings.

Re: For enyone on Be* on fast path
 

ME?
between 19 and 24Mbit

I did have 24 down 2.5 but it became unstable as i had the SNR profile set at 3 (norm is 6) so I had it reset back to 6.

P.s my connection is above the average though as im very close to the exchange.
