Multicast in the Internet is an all-or-nothing solution
|
|
|
Even Mcast-aware content owners must provide
|
|
|
unicast streams to gain audience size
|
|
|
|
Unicast will never scale
|
|
|
|
Splitters/Caches
just distribute the problem
|
|
|
|
|
Still
has a cost-per-user
|
|
|
|
As
receiver BW increases, problem gets worse.
|
|
|
|
Creates
a non-functional business model
|
|
|
|
Will
never bring ~real content to IP.
|
|
|
|
Must provide a multicast-only solution for content
|
|
|
owners; but how??
