ABSTRACT:
A method and apparatus for improved data communications over a token ring interface in which a target token rotation time value is a function of an initial target token rotation time value, the summation of the high priority token holding times for each node on the ring, and the time required to transmit a maximum size packet. Furthermore, the target rotation timer for the token ring network is activated only when the node is not transmitting in a synchronous manner.
