Technically correct, Infiniband is actually a variant of virtual cut through switching. If one want's be be even more pedantic you can also point out there are implementations of Ethernet that employ the same technology at a switching level.

What really makes the big difference though is the presence of the subnet manager. Which pre-programs the routing information into each switch at fabric bring-up time. This is what causes Infiniband to act like a circuit switched network despite ofcourse being VCT at the PHY layer.




Uh, no. You aren't using those words the way other people do.
