However, even ifwe are not aware of howlow-level details of networks are implemented, our data is actually being sent as lots of small packets, some of which might be lost or arrive out of order.

streams of bytes, instead of discrete packets
support for large messages
routing to ?nal destination
independence from the low-level network and hardware details
