Yeah, but that's load balancing of the network, not of the down streams the guy has. There may be an over-utilisation of the upstream he's on, but even if he was only on one downstream it wouldn't be any better is what I'm saying.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It is obviously related to peak time usage. Pretty sure that more users active can increase some type of errors. Not sure if that would be HEC/FEC or something else, or indicative of an amp on its way out or whatever though.

The packet loss makes me think its not as simple as utilisation.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Given each downstream channel requires a certain amount of upstream bandwidth to work, it does.

Considering one downstream channel uses up to 5-10% of the upstream channel capacity to run, fully utilizing 8 downstream channels with one upstream could result in up to 80% of the upstream capacity being utilized just to operate the downstream, while nobody is uploading anything. That leaves very little upstream capacity left over for actual uploading, especially given congestion issues can begin at above 70% upstream utilization

However if the network only had one downstream (aside from downstream congestion issues) that would leave at least 90% of the upstream capacity available, compared to the ~40-50% left over with 8 downstream channels in use.

There's an interesting article on the subject here.

The takeaway in the context of Qasi's post is that the frequency of ACKs sent back (through a busy) upstream on data received will slow the download (decrease throughput).

Whether or not that is a 5-10% overhead I'll leave to Qasi to justify, if he cares to. But it is an important point that he makes.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Believe it or not, this situation is nothing new to VM. Remember when the 50Meg first came out and had an upload speed of barely over 1.5Mbit? (If I recall correctly). The ACKs alone would nearly congest the upload stream in itself, yet it actually ran fairly smoothly (For most, there's always an exception). Anyway, there is a point in what you're saying but he's having this issue without actually utilising his downstream, which is the point I'm making - just HAVING 8 downstreams versus 1 upstream isn't the issue, there's obviously something else going on there.

I'd like to know where you're getting your figures, though, 5-10% of upstream per downstream for example. Are you referring to the available bandwidth for the connection (What profile the modem is set to), or the available bandwidth for the channels (8x50Mbit on the downstream, 1x~30Mbit on the upstream?) or what?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I now have 8 downstream but I dont know how many upstream, superhub is crashing 1 min after boot. I cant load the upstream page.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Probably a silly suggestion but could you go directly to your upstream page

Sorry if it's a daft idea. :( (I'll get my coat on the way off the thread. :D )

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

its fixed now, the issue was it couldnt get a wan ip and I guess whilst in that state in modem mode it isnt responsive. I will post a graph after some uptime.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Seems like a massive improvement on before.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

so far yeah, lets see how it goes at 6pm.

and yeah doh its already gone 6pm, 2US

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

something is going on right now
Maybe is local

2 days after waiting a year or so for the upgrade seems another is needed.

VM just cant get that modem count down enough.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Where in LE3 are you as I notice you're graph says " Bonded US "

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

fosse road area.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

same here after few days gone back up, then after 1-3 weeks gone down again
seems they will load balance it (or whatever they doing) by time
