We (BBC but Bogons does too) still have it but it's dying out, our transits are killing it, L3 gone NTT planning to. It was only used to peers though If it did come back we'd only be interested in V6 source specific but that seems unlikely, The people we'd be delivering to like BT/Sky would all do it privately On Mon Sep 02, 2019 at 05:48:55PM +0100, Marek Isalski wrote: > I mean, who actually watches live TV these days? On demand was about 5% vs 95% live so far, it'll go more on demand as thats the way the tech is moving. We've been adding multicast to the dash spec so that for the remainers it will use multicast if available so the home ISP (or 5g carrier as there is a broadcast mode in there it can tie into and use spectrum efficiently) can choose to embed our CDN or set up multicast and the client will take whichever works without user intervention. brandon
