window it can accept, so it can be practical for a subscriber
installation. It wouldn't be a good idea to park a bunch of
servers behind one of these links, but any receiving node that set
its TCP receive window to 2x the byte/sec capacity of the link
should see decent throughput.
No, you need to set things on both sides. The sender has to buffer
data until it is ACKed in case it needs to retransmit. So, its
buffer needs to be as big as the advertised window or the sender
buffer will effectivly limit the advertised window.
