Hi Fred, The nice thing about TSO/GSO/GRO is that they don't require any changes to the protocol as just implementation techniques, also they're one sided opitmizations meaning for instance that TSO can be used at the sender without requiring GRO to be used at the receiver. My understanding is that IP parcels requires new protocol that would need to be implemented on both endpoints and possibly in some routers. Do you have data that shows the benefits of IP Parcels in light of these requirements?
