Very Not up-to-date :) In fact, we should have it edited to make clear it documents a technical trial from many years ago. I’ll see where it’s hosted.. Just to echo the point about linear, as-live TV not going away - live events (Sport, News and others) are huge, getting bigger each year, and cause us, the provider networks and the CDNs the greatest challenges in terms of capacity and stability each year. The Beeb does a lot of multicast intra-network, for moving contribution AV around the business, and that’s well understood and works nicely - it helps if you use the same kit within the domain. The great hope of inter-domain multicast does seem to be dead, but the amount of work going into making HTTP-esque delivery of live media work at scale within the industry is considerable, and that has the benefit of sharing a *lot* of existing technology, processes and domain knowledge with the mostly-proven on-demand HLS/DASH/CMAF world. Offloading traffic as near as possible to the consumer edge of the network - but achieving that at the application rather than networking layers - is the ongoing trend. BTW - Hi Nick :) Paul
