Abstract
In a token ring transmission system, token loss causes selection of a leader terminal, which issues a new token. The leader terminal is chosen by selecting and storing a leadership selection reference value and then generating a succession of terminal identification signals and transferring them on the token ring transmission system. Each terminal receives the succession of signals and iteratively compares the terminal identification signals sequentially with the leadership reference signal. Each time a terminal identification signal exceeds the magnitude of the leadership reference signal, the leadership reference value is replaced with the value of the terminal identification signal. The first terminal detecting equality of a terminal identification signal with its leadership selection reference signal assumes leadership and issues a token.
