Just so happens that the current network build has multicast options :) Nice for live TV but really the network will need to handle alot of on-demand video

Most problems are the result of previous solutions...

Yeah but all service providers Mobile/Fixed line should give me unlimited/FS everything for $1 down payment!

Very informative posts here thank you all. Why is broadband so expensive for low bandwidth in nz! What's not expensive in nz... Might as well complain about every single products and services in nz.

I don't even know how i'd use a faster connection, maybe if high def streaming video reaches NZ then it'd be useful, if data allowances are increased to match.

I have always imagined it would be for things like video delivery from local servers. And to make that happen, the whole fibre network would need to support multicast

RF over fibre has significant advantages over using IP for video. Most large scale FTTH rollouts (FiOS being a classic example) all have RF outputs on their ONT's which feed into a STB.

RF over fibre frees up bandwidth for on-demand applications and improves contention for backhaul bandwidth. The only drawback I can think of is that testing for faults might need to use the same 1550nm wavelength. Would be interesting to see which TV broadcasters signed up to use it.

Time to find a new industry!

1080p: Considering the dismal overall performance of New Zealand's current ADSL network;

Seriously some people need to get a life - As JohnR says, there is no problem. 15Mb/s is really good! Most servers cant supply you with anywhere near this speed. What are you trying to get the backbone for a 100+ user ?organisation?

I am not sure why my life has entered this thread :\

I am afraid I will have to disagree with people who say there is no problem. I do understand the true costs of CIR grade network connectivity and that guaranteeing CIR grade transit to consumers is not possible. However, I see threads all over NZ based forums with users posting horrific (in some cases - actually - worse than dial up) speeds to international and sometimes national destinations.

I think this country would benefit from both ISPs and wholesalers being forced to publish contention data for their networks. We have a portion of New Zealand wanting a service which isn't being delivered and the service providers are all pointing the finger at each other with no actual progress being made toward a solution. To top it all off regular consumers cannot even open a channel of communication with Telecom Wholesale to find out if their link is likely congested or not. I, for one, like to know everything about a product that I am purchasing; especially in the case of a 'best efforts' based service.

I am not sure if I am reading in the right place but according to Telecom their new EUBA product currently has a single profile for internet 'Best Efforts' traffic which is 32Kbit/s per subscriber. The enhanced provisions are for traffic which is real time (I am assuming VoIP here) QoS grade.

From what I read this means that standard browsing/p2p/gaming will remain provisioned at a minimum of 32Kbit/s or am I incorrect?

You can access the information on the Telecom Wholesale website (Products > Broadband > Enhanced UBA) and download the Product Profile PDF (page 2).

So, if I am reading Telecom's paperwork correctly, we have an almost completely optical or ethernet based service with the only caveat being the copper link from DSLAM to ETP (and in most cases, also home wiring) and still only being allocated a minimum of 32Kbbit/s?

That seems a little low to me and also why I am worried for our supposed 'fibre future'.

The actual figure for UBR backhaul is 45kbps and both 75kbps and 100kbps dimensioning is now available at an extra cost to ISP's.

What does it mean when they say they provision 45kbps per subscriber? Is that the total bandwidth available to a group of subscribers? So a subdivision of 100 houses would have 4.5Mbps of bandwidth available? How does that work given a single download could saturate that?

No, it's not down to that level... It's determined by the retail ISP based on how many customers they choose to put over a handover link - there could be thousands.

Bear in mind that most (every) ISP, even if they run into contention at peak times, isn't contended 24*7. The decision they need to make isn't whether or not to provision over 100% of peak demand, but how long during peak they are prepared to accept contention. That's now a choice that the ISPs can make - they can increase the handover dimensioning to over double the baseline, and over triple what it was just a month or few ago.

If they want to provision EVEN HIGHER bandwidth, they have options for that too.

It's no longer about Telecom wholesale limiting things, it's about the retail ISPS willingness to spend more money to improve their performance. (Note that Telecom Retail is actively migrating customers from their old system to the new wholesale options, and every new connection is on the same basis as any other retail ISP)

Put simply, complaining about handover dimensioning restrictions isn't something most well informed people are doing anymore.

The current/new wholesale services are pretty good (EUBA + UBA + handover), they don't seem to be applying the older style handover link dimensioning at all currently.

Many people will still have their service provided over the crappier older services (UBS/BUBA + UBR + strictly dimensioned handover links).

Reasons for that are:

a) Earthquake work is taking priority over general provisioning jobs.
b) Smaller ISP's haven't got going with migrating their customers to EUBA yet.
c) You might still be connected to old hardware/ports in the exchange thereforce EUBA isn't available.

Things are improving, if you are on a new cabinet or upgraded exchange and suffering slow peak time speeds you might want to reconsider what ISP you are with and get on board one that's migrating customers to EUBA.

Johnr's comment is a flame to a powder keg without more information, Why does he believe there is no problem in internet speeds

No, They are just trying to figure out how to make use of the new options they have.
