For a long time there has been the distant promise that someday we would all just use IP multicasting for distributing content through the Internet. The idea that one could send a packet to one address and have it magically appear at multiple destinations was a compelling one. However IP Multicast has never taken off outside of Intranets. I believe that the fundamental reason for IP Multicast's failure to reach its promised potential is that IP Multicast does not scale very well. Specifically, each router on the distribution path of an IP Multicast must allocate memory to remember that multicast for the length of the multicast session. This means that as the number of multicast sessions that cross that router grow so will the amount of memory the router has to allocate. While the rate of increase of multicast sessions is exponential the rate of increase of memory required is linear.
It begins when management realizes that a systemic problem exists in the software they are developing, usually security, performance or reliability (SPR) related. Management gets worried and decides to bring in an expert, a guru who is to fix the problem.
There will not be one protocol to rule them all.
