ARBITRATING ACCESS TO A TIMESLOT BASED ON A PRIORITY SCHEME IN A TDMA NETWORK WITH ASYNCHRONOUS HUB

摘要

A method for arbitrating access to a time slot in a time division multiple access network in an asynchronous hub with a bus guardian is provided. The method including receiving signals from competing nodes claiming access to the same time slot at the bus guardian of the asynchronous hub, selecting one of the nodes based on a priority scheme, and relaying a message from the selected node and blocking the message from the non-selected node. Furthermore, the relaying of a message is interrupted when another node having a higher prority signals a request for message relaying. Thus, relaying of messages from contending nodes is done in a selective manner.
