How to tell if interleave is on?


[link to this post]
 
I just recently had BT Infinity installed a few days ago and been downloading, the speeds seems to be great (around 70 meg download / 17 meg upload) but my ping seems a bit high.

Around 45 for google and 50 or less for gaming I was expecting the ping to be a little lower, here are my stats how do I find out if interleave is currently switched on?

Your interleave depth is the 'D' field reported by the xdslcmd tool. See [1]

It has two parameter values. The first value is the downstream interleaving depth, the second for upstream.

Yours is apparently 1237 (down) and 1 (up).

Also, varying levels of Impulse Noise Protection (INP) & delay go hand in hand with Interleaving.

I've found that if you upload a video to youtube, you'll get packet loss on it so there will be distortion on it in parts if you have a fastpath connection.

Just my simple alternative wink

That's got me puzzled. Do you mean anyone watching youtube will have problems watching anything from it, or the OP will have a messed up upload if the upstream is fast path? (Which it is, as are huge numbers of punters').

Messed up upload makes no sense, as the YouTube server will reject the video if it has had bits or bytes altered during the upload.

Most video formats do not take kindly to having bytes changed in the middle of them, MPG could be truncated safely, but that was about it.

Everytime I upload a video to YouTube from my house, which is a fastpath connection, the video becomes distorted for a couple of seconds when it gets played back.

When I tried uploading on an interleaved connection with similar speeds at my grandads house, the video was fine.

Seems like a weird coincidence.

Nothing to do with interleaving.

I think you missed my point. Downstream interleaving doesn't necessarily mean there is also upstream interleaving, as illustrated by the line stats in this case.

I agre with MrSaffron and zadeks though, I don't think interleaving has any side-effects on youtube uploads, and if anything on downloads I would expect fast path to be the one with issues.

Unless your router isn't powerful enough to unscramble the interleaving on your connection.
