SM is making his contribution as I write. For several years, I have been with Telefonica O2 as an ISP. This=20 network gave subscribers a dynamic ipv4 address which did not change=20 unless the gateway WAN MAC changed. Sky bought the network to get the=20 400 000 subscribers and migrated everyone to their network, closing the=20 O2 setup. I left, moving to TalkTalk, a network which gives out a=20 different ipv4 address every time it retrains, two or three times a day=20 at present, using their proprietary dynamic line management unchanged. I threw away the supplied Trendchip box, and use a 1483-bridged TP-Link=20 TD-W8970 to connect to the phone line. Here, PPPoE always comes up using the 3.10.18-1 build. Henet is more=20 problematic. I lose ipv6 connectivity every five or so retrains, and=20 have to reboot the router. The latest builds allow concurrent downloading or the use of torrents=20 and video streaming 90 per cent of the time. tc-stab is apparently=20 functional. Changing ISP has been a very illuminating exercise from the point of=20 view of 'bufferbloat'. O2 lost a lot of packets through their site=20 screening mechanism. TalkTalk subcontracts its deep packet inspection to = Huawei in China. This minimises packet loss. Have set AQM to circa 70 percent of download sync and 95 per cent of=20 upload sync, based on empirical incremental changes. On 12/11/13 05:47, Richard E.
