  1. The consideration many people are not taking into account is that these are much longer lived flows than most networks are used to dealing with. Most of the flows rarely if ever got past their TCP Slow Start. Nowadays with these long lived video downloads, on-demand, YouTube-esque sites, etc we are seeing more and more flows get to their full bandwidth potential, maximizing the TCP Window size and lasting much, much longer.

    This pretty much means the end of flow-cache switching systems that are not intelligent enough to pre-cache or use a topology derived caching system.
