Can they claim SLA credits for it being down/unusable if they're only getting 1% of the throughput they paid for? And are they a captive audience or not?
No SLA, residential customers.1% is quite unlikely to happen, it would require every customer in a very large deployment to be trying to download >1mbit/sec at the same time.
Peak average usage for most UK broadband installations seem to be between 20 and 100Kb/sec. I'm working on the basis of 300Kb/sec because our access speeds are much higher.
(this would suggest 300Mbit/sec peak for 1000 users, but my question is whether we'll see that level of aggregation at 1000 * 100Mb on 1GE, or whether it's going to be very 'peaky', and we'll only see that smoothness when we aggregate 10-15 buildings onto 10GE)
What do you do on Patch Tuesday?
