Multicast addressing is a network technology for the delivery of information to a group of destinations simultaneously. It is similar to peer to peer data delivery.


If you were to set up a Multicast stream, the central server would only deliver one stream, with all other connected clients relaying that stream.


Most stream providers use unicast data delivery. This entails creating a data connection to each requesting client. This is very bandwidth intensive and poor use of resources.


The Internet currently uses the IPv4 protocol for data delivery. The next generation protocol ( IPv6 ) offers greater security, many many many more network addresses and greatly enhanced Multicast support.


There are several providers that offer FREE access to IPv6 networking. Two of these providers incorporate Multicast support. Go6 and Sixx.


A stream provider could provide a IPv6 Multicast node to allow IPv6 users to connect with that node and recieve streams. Connecting to IPv6 requires less than 5 minutes. Enabling Multicast support is just as simple.


For linux users go to synaptic and install Tspc and ecmh or mrd6. Tspc is the tunnel broker daemon while ecmh / mrd6 enables Multicast routing.


You can test your multicast compatability by installing ssmping from synaptic.

Multicast is not like regular P2P. If a client in the chain drops off, the chain will continue to function.

This technology has been around since the early 90's and is very mature.


Several broadcasters in the UK use this technology with excellent results.
