What’s Wrong?
• 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??
