So I would have liked the above to not say "broadband lines" but instead said ADSL(2+) broadband lines (because the above statement only relates to ADSL(2+) afaik), and also that the packet losses can be non-trivial for some and that ISPs don't turn on interleaving out of ignorance. It's hard to measure customer impact of "errored seconds" which is the only way the ISP can see packet losses. Also, these errored seconds can be quite severer when it comes to number of packets dropped.
it applies to ADSL to court.
We actually did talk about having a self-service portal where the customer could choose their preferred profile, either fast (no interleaving), 4ms or 16 ms interleaving, and also their safety margin to 6, 9 or 12 dB. Fast or 4ms interleaving worked well with 12 dB SNR margin (which means lower latency but also lower access speeds), whereas 6dB margin often required 16ms interleaving to work well.
Was that successful? Did customers use that? Usually it is not, but I'd like to know about your experience. Luca _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
