Yes it is technically feasible to perform a push-type operation and send data to someone without their consent. But that's generally regarded as an attack, rather than legitimate network traffic. I don't have any hard numbers but I would guess that at least 90% and very likely 95% or 99% of all internet traffic is pull-style. Transferring data between two parties on the internet for any reason usually goes hand in hand with one person wanting to receive some data and another wanting to send it. If the sender doesn't want to send, no transfer takes place. If the receiver doesn't want the data, it's regarded as an attack. I am having a hard time coming up with legitimate situations where someone sends data to my computer without my permission (express or implied) and that doesn't seem like some kind of attack. But I'm also open (at least I'd like to believe I am) to someone cooking up a situation that proves me wrong.
