Hey, wait a minute! Even assuming no errors, arbitrarily high data rates
and arbitarily fast processors interpretting the protocols, there is still
propagation time across the channel to contend with. Assuming a window
size of one (a.k.a. "stop and wait") you get at most one frame per round
trip time, i.e., a finite maximum data rate. A larger (but still finite)
window size of W outstanding and unacknowledged frames raises that bound
by a factor of W, but it certainly doesn't give you infinite throughput.

Does that clarify the situation, or am I missing something deeper?
