Thumb On the Scale? Study Finds 5 of 7 Broadband Meters Inaccurate

The president of the firm who audits many of the country's broadband meters says that he can't certify the measurements produced by five out of seven of his clients' meters because they don't count your bits correctly

      Caps are about the money, even if the reports are wrong. The caps are there for money, and the sloppy is there because they are cheap. I know the ISP I worked for that metered DSL got a byte output from the interface, and imported that into a database. From what we could tell, it was perfect, except for any lost packets. The bonus was, doing it on the user DSLAM interface, any cache hits would count against their cap, and would match their LAN records.

      Government regulation is bad in almost all respects when it comes to the economy. Capitalism works best when it's unfettered and transparent. The laws the government should impose should not put chains on businesses or consumers. What the government should be doing is making the market more transparent. Don't make derivatives illegal, make describing exactly whats in them required before sale. Don't dictate what speeds or services ISPs can offer, require the ISPs to use common terms and conditions that consumers can understand. Just as you say, a certain speed should be exactly that. None of this "up to" bullshit. If there are limits on how much you can download, that should be clear and upfront, not buried on their website. Their traffic shaping policies should be clear and understandable. The way they measure your use should be standardize. It would help both the ISPs and the consumer. We need something like the FDAs nutrition labels but for technology.

  8. Fast and wrong, or slow and correct. by PlusFiveTroll · · Score: 5, Informative

    Building an incorrect bandwidth meter is easy. Incorrect meters will calculate your bandwidth like ( 'MTU size' * 'number of packets' = usage), which will over estimate usage by a large margin (30% off is common), since a large number of packets are much smaller then MTU, DNS replies for example. It is 'somewhat' more accurate to take ('average packet size' * 'number of packets') per user, since different usage will come up with a different avg_pkt size. Counting each packets size and keeping track of it is the most accurate, but also the most resource intensive therefore the least likely to occur in bulk by the ISP.

    Another place that can cause a significant skew in total bits is where bandwidth is monitored. Most ISPs count traffic before the restriction of your slow connection, therefore packet loss and re-transmits get counted against you (if the ISP uses no, or a bad queuing discipline this can end up being a significant amount of bandwidth). Monitoring how much was downloaded is best done on the CPE, such as the cable modem or dsl modem, but that would lead to firmware hacks and such to lie to the provider.

      It's also amazing how often equipment gets that byte count wrong (I've seen it often with ISP head end equipment). Also there is no shortage of equipment that can overflow 32-bit byte counts faster than the ISP samples.

  10. What bytes are we measuring? by AlphaWolf_HK · · Score: 4, Interesting

    I don't know how many on slashdot know networking, but there are different ways of measuring bandwidth. Are we measuring layer 2, or layer 3? Further, layer 2 can often have multiple encapsulations before even taking layer 3 into consideration. Take for example DSL which frequently uses PPPoE, which means we have both PPP and Ethernet frames in addition to the IP data and everything encapsulated therein. And if you include DSL interleaving, then do we also include the packets that had a bad checksum and were therefore discarded? (in many cases there are a lot of these) That *is* data usage by all definitions. Do we also include ingress packets that were dropped due to bad checksums? Again, that is data usage.

    In my opinion, the problem is that there aren't any standards defined for measuring bandwidth. Also in my opinion, that definition should be layer 3 traffic only and nothing else.
