There are a LOT of dsl capable devices in openwrt barrier breaker. I am curious if anyone has tried one of late? I just got back from "farmstock", and as effective as software rate limiting can be, I imagine that when someone is stuck at a line rate of 1Mbit down and 384k up that doing it in hardware is superior...
This was a classic bufferbloated plot on the existing 384k uplink there: http://snapon.lab.bufferbloat.net/~d/farmstock/farmstock_upload_showing_1700ms_latency.png Downloads were not so bad, "only" 1sec of buffering... http://snapon.lab.bufferbloat.net/~d/farmstock/farmstock-short-download.png there appears to be some level of ack prioritization or fair queuing in play here, an internet radio flow would survive the onslought of netperf-wrapper for 10s of minutes... and generally full download rate was achieved at a huge cost in the upload. http://snapon.lab.bufferbloat.net/~d/farmstock/farmstock-bidirectional.png you can imagine under the influence of two dozen millenials with 1 or more phones/tablets each, the network performed rather badly during the show. Anyway, so I figure that there are a selection of DSL capable openwrt platforms now someone can fiddle with.... PS wow was there a lot of traffic on the list while I was away. I am way behind. -- Dave Täht NSFW: https://w2.eff.org/Censorship/Internet_censorship_bills/russell_0296_indecent.article _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
