WebThe maximum jam-time is calculated as follows: The maximum allowed diameter of an Ethernet installation is limited to 232 bits. This makes a round-trip-time of 464 bits. As the slot time in Ethernet is 512 bits, the difference between slot time and round-trip-time is 48 bits (6 bytes), which is the maximum "jam-time". WebSep 28, 2005 · CSMA/CD (carrier sense multiple access/collision detection) is the most widely used protocol (i.e., set of rules) for determining how network devices respond in the event of a collision .
