1 Bandwidth # of bits per second that can be sent.
delay Time to send a message from point A to point B Components of delay = Propagation + Transmit + Queue (delays in send, demux queues) Transmit = Size / Bandwidth: Time between when 1st bit enters link and last bit enters link. Propagation = Distance / SpeedOfLight: Time between when last bit enters and last bit leaves link. Propagation versus Transmit delay If you’re sending 1 byte, propagation delay dominates If you’re sending 500 MB, transmit delay dominates
