The sixteen bit IP id field and the 16 bit max packet length limit a particular connection to 4GB/255 seconds or about 16MB/sec. Sorry if I'm being overly ignorant but I can't make sense out this. Where does the time come into this as a limiting factor other than the available bandwidth of the underlying hardware?
