Upstream/Upload??

[wifi_dude]

Hey everyone.

Quick question. ADSL is bundled as 512 downstream, 256 upstream, or 1024 downstream, 256 upstream right?

Now is this set on the dslam itself? Or maybe on the VC circuits on telkom's cisco routers (if they are running cisco).

Or is this the responsibility of the ISP itself.

The reason I ask is, I have an 512K business solution from IS and I normally get around 30KB upload speeds. Sometimes, it peaks at 46KB upload. I have never seen it run at its 256 cut off mark (which would be 24kb/s).

AFAIK it is set at the exchange (Most ISPs don't even know you line speed).

256Kb=32KB?? (-1 or 2 KB for overhead)

 

[Kryon_MC]

yup, it is set at the dslam at the exchange!

JayM is right about the max upload being 32KB.

You must also take into consideration that certain protocols allow for compression and the applications using these (and taking advantage of the compression) will probably report according what the total size of the uploaded/downloaded uncompressed information throughput rate is and not the actual amount of compressed data throughput.

Some files (eg. text files) thus appear to be going through at much higher rates.

ah that explains it. Sorry about the 24kb... had 12kb on my mind, thought it was 128kb and doubled it to = 24kb

Pitty, jsut now I thought I was a lucky fish.

so its impossible to ever get 512/512 ?

Uploads on our 1 mbit line seem to be capped at 320kbit, not 256k.

I hate having fast uploads on Iburst, around 200-300kb, it just makes capping come quicker, i mean I hardly ever use my upload speed, it just sucks having a faster upload speed on DC++ and other p2p. Yet Telkom seem to be very leanient on their upload speed often having it go over it's max, while that wont be happening on 512 or 1024 ADSL for download speeds.
