Zen Traffic Pioritisation


[link to this post]
 
I run a village broadband system which supplies 12 houses. The feed is by telephone line from the exchange at the next village, Brandsby (MYBBY).

At the moment I use Zen Office but with the new download limits I could move to Zen Pro, however I would then lose Traffic Pioritisation. As BT is the only supplier at the exchange would the village system notice any difference in performance.

Thanks

Hard to say, but with 12 people off the system, the chances are that usage will be increasing anyway, so stay where you are.

What is the upstream connection speed now? I expect 832kbps, so what would it be on Pro? 832 or 448? It could be relevant with 12 users, as filling the upstream could slow the downstream.

Pro should be 832 still

Thanks for the replies.

Usage isn't a problem, at the moment we use about 90gb/month, way under the Zen Pro new limit of 200gb.

I just like to keep the costs as low as possible, without affecting the service, so i can undercut the competition!!!!!!

"IPStream Max is used to provide Zen 8000 Pro, Active and Lite

IPStream Max Premium is used to provide Zen Office 8000 and Zen Office 8000 Max"

so Pro would be 448 upstream / lower priority if its not WBC.

In my experience the Premium of Max Premium is significant in terms of performance at busy times on small exchanges.

Unless i am misunderstanding, according to the Zen website Office and Pro are both 1mb upload.
the only difference is Traffic Pioritisation

The 1Mbps upload refers to the 80% of lines where 21CN WBC is available.

On older 20CN IPStream lines, then 448 is the standard, and 832 is the priority version.

As the others seem to have agreed since I raised the question, Pro is probably only 448kbps upload. The easiest thing to do is to ask Zen.

Even at 448kbps it isn't necessarily a killer point. It depends how much uploading you do, bearing in mind some of the things you listed may upload as well. Desktop iPlayer used to, I don't know if it still does. The streaming iPlayer doesn't.

As well as that, everything that comes down generates an ACK(nowledgment) requesting the next chunk, or a re-transmit request for any uncorrectable errors.

People doing mammoth film downloads for instance, with hundreds of streams, can find they saturate the upstream with ACKs, so the download has to slow down and things start queuing. If they reduce the number of streams, the upstream can cope, and they get faster downloads.

This isn't quite what you intend to do, but I expect you see the principle. You can fill the upstream and degrade the downstream as a result.

But it's an "If". It could be fine on 448kbps.
