More precisely, this is a new mode of operation that does encryption 
and authentication in one pass.  It's also amenable to parallelization, 
thus making it suitable for very high speed networks.  (Traditional 
modes of operation, such as CBC, are problematic, since every block 
depends on the encryption of the previous block.)
