To avoid flow and congestion control problems in the ARPANET, a host or IMP would send a packet to its neighbor (Host or IMP) and wait for a RFNM (Request for Next Message, pronounced 'rough-numb'). The ARPANET had 56Kbps lines and maximum PDU size of 1024 bits. Assuming that the speed of light in copper is 2/3rds the speed of light in a vacuum (c = 3 x 105 km/sec), was this a reasonable design? When would it no longer be a reasonable design? On this one, look up anything you think you need on the web.
