- hristov 15y agoThere actually is a multicast standard on the internet. It uses UDP. Basically, instead of sending out multiple streams of packets for each viewer you send only one stream and the routers copy the packets into new streams as needed along the way. http://en.wikipedia.org/wiki/Multicast http://en.wikipedia.org/wiki/Multicast I am not sure how often it is used and whether the newer routers still support it even.
- randall 15y agoI have a huge dream about multicast, but on the public internet, it doesn't happen. Most of the time it happens on private IP networks (think FiOS TV, Uverse, etc., though i'm not sure if they use it.)
