Re: Application Throttling/Management
 

Andrew, what do you mean OC connection? OC what and where? Wasn't even aware we used OC in the UK.

Re: Application Throttling/Management
 

For fear of being the village idiot, what does the acronym 'OC' refer to in this context?

Re: Application Throttling/Management
 

Optical Carrier

I dnt know who excately uses it but some places do and it mostly be isps backbones i guess

OC12 Connection ie Optical Carrier Connection used on fibre

Re: Application Throttling/Management
 

OK understand, STM-4 then. We use SDH in the UK not SONET and OC is a purely SONET thing. Was the mention of 'OC' that confused as I've never seen SONET on an ISP network here. Thanks for clearing it up.

Re: Application Throttling/Management
 

I can sort of verify this.

Both my sisters use utorrent to download stuff.

One is on a VM 2meg connection, the other on a orange adsl connection.

Both were running slow and I told them its because they didnt cap their upload speeds on utorrent, when I uncapped it on the orange dsl line, utorrent itself sped up as well as other stuff like web browsing. On the VM line nothing happened everything stayed slow and didnt even get a boost on utorrent speeds.

if VM start protocol throttling aka like plusnet and BT broadband then I would love to know how they justify it.

VM own their own network and backhaul, isps reselling BT wholesale services have to pay very high traffic costs to BT wholesale which is why traffic shaping is common on adsl and is why isps like BE and sky/ukonline have yet not had the need to do any throttling. VM also do charge higher prices than adsl retail, a up to 8meg on adsl can be quite easily had for under £20 and sometimes under £15 yet VM get much more then that for all high speed connections regardless of usage. So I have defenitly changed my views now on this and I think its a blatant attempt at profiteering at the cost of letting the service go downhill.

Anyone hoping that ofcom steps in dont hold your breath, so far they have ignored all the traffic shaping stuff on adsl and the ASA has no problem with isps selling unlimited and then limiting it. The only thing ofcom have done is asked isps who traffic shape to clarify it to customers and show how things are shaped. I expect VM have took the stance most other isps are doing so why not us.

I havent seen any slow downs on my torrents was getting 500Kb/s plus

Re: Application Throttling/Management
 

virgin dnt own the backhaul onto the internet only there fibre network once it connected to the backbone of the internet they pay for traffic jsut like bt does as well, but i aint saying this is a excuss for them just trying to clarify a slight misunderstanding.

Re: Application Throttling/Management
 

I think Chrysalis was referring to the costs to ISPs who interconnect with BT Wholesale. That cost is far higher than the cost of internet bandwidth.

Re: Application Throttling/Management
 

I thought that as well but they also go on about virgin making profits but since virgin have to pay for the backbone then they do lose money but i still am not staying this is justified if it is getting implemented

Re: Application Throttling/Management
 

Nearly every ISP has to pay to get their traffic onto the Internet from their internal network, however the main reason for shaping is the huge costs to BT Wholesale. Note Sky for example. They shape on the BT Wholesale supplied service but not on the LLU, while Be are only LLU and don't shape at all.

Re: Application Throttling/Management
 

i think trying to base any assumptions on torrent speeds is just crazy. Torrents are not a valid means of testing for throttling as there are so many variables !

Re: Application Throttling/Management
 

I would test using newsgroups, might get better results

Re: Application Throttling/Management
 

Not when your connected to 100Mbit seeders/seedboxes and cant pull more than 50KB/s ;):p:

Re: Application Throttling/Management
 

Come on tho Trax test connection speeds via torrents isn't going to work is it really I am ok with my speeds on torrents and I am yet to hear of people calling and cancelling over it so lets just wait and see

Re: Application Throttling/Management
 

i have had no issues with torrents was getting 2.1Mb/s last night !
