The available address space for multicast in IPv4 is limited. IPv6 vastly expands this space. And here, I may have been guilty of putting the cart before the horse. Inter-AS multicast does not exist today because the motivators are not there. It is absolutely possible, but providers have to want to do it. Consumers need to see some benefit from it. Again, the benefit needs to be seen by a large market. Providers make decisions in the interest of their bottom line. A niche service is not a motivator for inter-AS multicast. If demand for variety in service provider selection grows with the proliferation of IPTV, we may see the required motivation for inter-AS multicast, which places us in a position moving to the large multicast space available in IPv6.
I don't think I'd be hanging my hat on IPv6 operational frobs at this moment in time. But that's just me. :-) $.02, - - ferg -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.5.2 (Build 4075) wj8DBQFFo+oXq1pz9mNUZTMRAuSaAJ47tTGFI+kTaZwOO2D6CHOWmIn6eACgyZzd xy6wZ7sFYsU3jeU2a3XIBq4= =aRhp -----END PGP SIGNATURE----- -- "Fergie", a.k.a.
