I realize that this is a bit of an over-simplification in an internetworking environment, but I've always liked this paraphrased summary I once read in the context of "transport": delay = elapsed time between first bit out of a transmitter to first bit into a receiver (this accommodates such things a propagation delay and inter-nodal processing delay). latency = elapsed time between first bit out of a transmitter to last bit into a receiver (this accommodates, in addition to the above, such things as serialization delay which, of course, depends on such things as bandwidth). I think that's fairly close to the original description that I read somewhere years ago. The two terms seem to be used almost interchangeably these days, but it seems a distinction is worth making.
