That's absolutely a concern Mark, but most of the CPE vendors that support doing this are providing enough juice to keep up with their max forwarding/routing data rates. I don't see 10 Gbps in residential Internet service being normal for quite a long time off even if the port itself is capable of 10Gbps. We have this issue today with commercial customers, but it's generally not as a much of a problem because the commercial CPE get their usage graphed and the commercial CPE have more capabilities for testing.
I suppose the point I was trying to make is when does it stop being feasible to test each and every piece of bandwidth you deliver to a customer? It may very well not be 10Gbps... perhaps it's 2Gbps, or 3.2Gbps, or 5.1Gbps... basically, the rabbit hole. Like Saku, I am more interested in other fundamental metrics that could impact throughput such as latency, packet loss and jitter. Bandwidth, itself, is easy to measure with your choice of SNMP poller + 5 minutes. But when you're trying to explain to a simple customer buying 100Mbps that a break in your Skype video cannot be diagnosed with a throughput speed test, they don't/won't get it. In Africa, for example, customers in only one of our markets are so obsessed with speed tests. But not to speed test servers that are in-country... they want to test servers that sit in Europe, North America, South America and Asia-Pac. With the latency averaging between 140ms - 400ms across all of those regions from source, the amount of energy spent explaining to customers that there is no way you can saturate your delivered capacity beyond a couple of Mbps using Ookla and friends is energy I could spend drinking wine and having a medium-rare steak, instead. For us, at least, aside from going on a mass education drive in this particular market, the ultimate solution is just getting all that content localized in-country or in-region. Once that latency comes down and the resources are available locally, the whole speed test debacle will easily fall away, because the source of these speed tests is simply how physically far the content is. Is this an easy task - hell no; but slamming your head against a wall over and over is no fun either. Mark.
