In a Carrier Sense Multiple Access (CSMA) communication system a plurality of terminals share a common transmission media such that each terminal senses traffic on the media and transmits only when no other terminal is transmitting. The delay time between when a terminal transmits and when the transmission is received is called Carrier Sense Delay (CSD) and is critical in determining network performance. Each terminal monitors its own transmission, and if an error is detected in the transmission, it is aborted and retransmitted. The presumption is that the error was caused by interference with another sender. During very high traffic periods the network may become overloaded due to interference retransmissions.
