> Because IP multicasts are broken as designed? And because (I guess) Internet lost such thing as, I do not know exact name, fixed addresses for the fixed services: for example, 254.0.0.1 for DNS, 254.0.0.2 for mail relay, etc etc. First IP drafts seems to had such ideas, but then this ideas was lost, and that make media caching more difficult (through possible) task to realise. > In any case, L3 mcasting seems to be pretty much dead. Replicating I better prefer to say _it's the train which is over already_. Existing network have a much of multimedia sources, and they don't use multicast. Now there is easy to add caching and autho-replication then to build parallel multicast network based on very complex and suspicious mechanisms. Through, multicast can feel itself well - in the end LANs.
