ABSTRACT:
This invention relates to a method and apparatus for determining which bus should be used for transmitting data to another station of a dual queue, dual bus DQDB network. Initially, data is transmitted over both buses. As each station receives an entity of data, such as packets or cells, over one bus, each entity including the identification of a transmitting station, the receiving station updates its memory to record that entities of data to that transmitting station should be transmitted over the other bus. The bus selection record is audited when packets are received to confirm its accuracy.
