You mean the billing meters ;)
TelstraClear: We don’t and can’t accurately measure traffic that passes through your modem. As I noted in an earlier post, we can ‘see’ your modem (ie, we know it’s there and is talking to our network) but we have no way to meter at the modem to count the amount of data it’s sending, receiving and passing, or receiving and rejecting).
TelstraClear: All we know is that a packet of data has your IP address on it (whether sent by you or addressed to you), so that is what is counted.
In cases where we give our customers zero-rated access to content (such as TradeMe, our Steam server, ClearNet video, Ziln and some others that are in the pipeline) we look at the IP address it’s from and the counting software ignores it.
(GZers are a bright bunch!).
Others have talked about how ISPs operate.
I don’t know about any others, but TelstraClear builds and maintains networks that carry traffic (data) to and from those requesting and sending it. Every packet has a cost in infrastructure, equipment, software, the electricity to power it all and the people needed to keep it running. Each year we invest around $100m in our network alone. Our profits (a small loss this year, but attributed to the costs incurred in the earthquakes) aren’t exorbitant. Going back to the last ‘normal’ non-earthquake year, our profit (before interest and tax) was $16m. You can see the figures for 2009/10 here: http://www.telstraclear.co.nz/company-info/media-release-template.cfm?newsid=366&myear=2010 and for 2010/11 here: http://www.telstraclear.co.nz/company-info/media-release-template.cfm?newsid=420
As I also noted in another post, the traffic counting system is accurate, and the data billing is accurate.
The online meter is generally close to real-time and is always accurate up to the second of the date/time stamp on the meter (have a look under the chart and three boxes of written detail at the bottom). For example, mine noted this morning at 09:40 am:
This estimated usage covers the period up to and including 20/09/2011 08:46:14 and excludes any usage via any ISP other than your TelstraClear ISP
We state at the bottom of the page:
Note: The usage meter information is provided as an indication of your usage, the information you receive on your bill is authoritative. In some circumstances information may be a day behind. For your security, password details are encrypted before being transmitted. We provide this service in order to help you estimate your usage. Traffic you consume is your responsibility to account for, and will be charged as per your bill
While it’s technically possible to have an online meter that provides more data and closer to real-time data that would involve a great deal of computing power (and associated investment and running cost). As PenultimateHop noted earlier, the costs are already substantial.
We believe that our customers receive more benefit from investment in network improvements
than they would by knowing to the nearest minute (rather than nearest hour or so) how much of their data has been used. If you want to monitor your data, you can check every hour or two and (usually) have an accurate update.
Hope this is useful.
Cheers, Gary
BruceHamilton: Off-topic, but to clarify. The retail petroleum industry in NZ is regulated. Retail fuels sold in NZ have to comply with the the Engine Fuel Specifications Regulations ( 2008 ) + amendments. There are many other laws, eg HASNO covering the industry, but for this discussion the above define the minimum fuel quality, and retail operations are also controlled.
BruceHamilton: Fuel retail dispensing and measurement systems comply with the calibration requirements of the Weights and Measures Act, which requires at least an annual independent calibration by an accredited organisation using traceable ( to NZ National Standards maintained by IRL ) devices. That act covers many commodities.
PenultimateHop: I still think Government regulation in this sector would be a pretty bad outcome.
PenultimateHop:
I suspect on global (and probably even across NZ ISPs) average, billing systems _under_ bill users overall for usage, especially when netflow based.
DonGould: You have also suggested we should just motivate Telstra to deliver 1Tb plans (16 times the current value going on Australian prices).
However you have not detailed how we should do this.
DonGould: You have simply said we should just leave Telstra... and go where? I'm not even in an ADSL2+ coverage area according to Telecom.
DonGould: How does IP Accounting compare in your view?
DonGould: Also why is netflow lossy? I've seen no indication in the Mikrotik documentation I've read so far that indicates it's anything but accurate for each flow record that's delivered.
PenultimateHop: b) Route engine performance can be impacted by high netflow sampling, e.g. on a router which only has a 1G bus from the line cards to the RE you will not be able to sample more than 1Gbps of flow data, or you'll overwhelm that bus
Users can not turn their modems off and be assured that traffic hitting their IP address is not metered, so there is very little point in turning the modem off over night or while you are away. Is this correct?
So, in short what you are saying is that you meter based on traffic thrown at the IP address. So even if the modem is off, any traffic thrown at the IP address is counted by the ERX. Is this correct?
Does your company publish a list of those (unmetered) IP addresses?
I do not have confidence in your billing systems.
Which is it?
Accurate or estimated?
So again note my bold - are you saying that users must wait until the end of each billing period to understand how much data they have used?
TelstraClear: Hi Don,
Here are the answers to your direct questions. We won’t comment on anything else as we respect your right to hold whatever opinions or beliefs you wish. We're happy to answer further questions.Users can not turn their modems off and be assured that traffic hitting their IP address is not metered, so there is very little point in turning the modem off over night or while you are away. Is this correct?
That is basically correct. That’s why I used the analogy of the postie delivering the mail whether you’re home or not. Turning the modem off means no traffic will be sent by you. It won’t stop traffic addressed to your modem’s IP address from being sent to the modem – powering off the modem simply means that it won’t pass from our network to yours.So, in short what you are saying is that you meter based on traffic thrown at the IP address. So even if the modem is off, any traffic thrown at the IP address is counted by the ERX. Is this correct?
Yes, as noted above.

Gary: That is basically correct.
Gary: We don't publish IP addresses. The sites that are unmetered for TelstraClear customers are at www.unmetered.co.nz (this is linked to from the Broadband pages, eg www.telstraclear.co.nz/residential/inhome/internet/).
Also www.telstraclear.co.nz/sub-sites/gaming-steam/
We’re working to bring our customers more unmetered sites.
Gary: If you wish to see your account’s data from the traffic counter please let me know what month you’d like and I’ll ask one of the specialists to provide it to you.
Gary: We don’t make technical information on the traffic counter or billing systems public as agreements with our systems providers prohibit public discussion of their commercial property.
Gary: Our systems are monitored, checked and audited.
Gary: Our data counting system is accurate and your bill is accurate.
Gary: We have a project underway to get more accurate time stamping on the web usage meter to improve this and further assist customers.

I gave my time and loyalty to your company, yet today I feel fobbed off. I clearly don't trust in your systems and I feel lied to and miss-lead on many levels.

freitasm: I don't understand why the surprise. This seems to be the norm in the industry. Not only ISPs but hosting providers will charge users by the traffic directed at their IP, regardless if there's a box at the end of the pipe receiving those bits.
