Re: Ellacoya So folks throttling appears to be the trend of ISP's in Canada. The Rogers forum is jumping with the information of the »www.sandvine.com/solutions/default.asp . It's another unit similar to the Ellacoya. It also states Bell (Sympatico) is also a customer of theirs. That leaves us in the dark about Telus...hmmmm ... wonder what they are doing?!?
Briefly comparing the two with the info on their respective web sites IMO the Ellacoya is a little bit nastier. |

my point always was that throttling is possible only for capping total bandwidth, but not for the filtering this or that specific protocol.
Sure they can prioritize traffic from/to their own video/voice servers above any other kind of traffic, but thats it.
Cable industry has a huge problem cable subscribers are yet to discover. Cables will have eventually to install separate CMTS in every building if they want to provide video on demand service and interconnect all these CMTSs (or hubs) with fiber.
I mean that the cable companies are only starting to invest money. The vast part of the investment is ahead. And it should be done in the conditions when legal video on demand costs $8/view. no way it is going to work. i would prefer to go to Blockbuster if to choose to pay 100USD for the high-speed connection and another 40USD for the movies. i can "deliver" movies myself.
In areas with low population density it is going to be especially painful to put fiber only to serve a small community with 5 or 6 families.
returning to traffic policy. ISP should reach clear decision do they drop P2P packets or do they cache the data to facilitate data transfer. P2P networks will fight back in the former and cooperate in later case.

i sent following
Evaluation of my approach in the Rodi project (see »larytet.sourceforge.net/btRatDesign.shtml#4) i suggest to encrypt the payload of UDP packets and fake RTP traffic including faking SIP call establish.i will appreciate any technical opinions regarding this idea
thank you.
Frankly I do not expect any answer, because in my view there is a fundamental problem with this kind of devices and there is no reason for their staff to spend valuable time and read my wrongly spelled humble ramifications but we will see. |

Either Shaw has already done this or they've gotten around it somehow, as I can order on demand movies from my remote. |

Nanaimo, BC | I am able to order video on demand from the shaw on demand website that goes to my tv, as well I can order ppv off my remote from shaw as well... its great not having to rent anymore  |
|
| So can I, shaw does not need a CMTS at every building to enable SOD. It can simply go over different analog frequences that are available to them (not occupied already). |

ultimately you probably want to order anyone of 10,000-20,000 titles kept by Blockbuster and 30% of the customers watch VoD simultaneously and of course you want your movie real time wihtout waiting 15 minutes for it to start on this channel or other. this is more or less service you expect. and yes, HDTV only.
throughput of the coax if all signal is digitized (no analogue channels at all) is about 3GB. Bandwith required for single movie in HDTV quality is about 10M. We get 300 different high quality channels behind single hub. let's say 1 thousand. single hub typically serves today between 5,000 (small) to 20,000 (large) subscribers. average is somewhere in 8-10K area |
