The basic premise for this paper is the observation that for all network communications, there is a non-zero (and often considerable) delay between the act of sending an information and receiving a reply. The effect should be contributed to the physical constrains of the medium, and to the data processing times in all computer equipment. A packet storing a piece of data, just like an orange with a message written on it, once pushed travels for a period of time before coming back to the source - and for this period of time, we can safely forget its message without losing data. This is an old idea, but a fun one... Juggling with packets |
