Abstract
A data packet switching arrangement wherein data packets are switched into a transmission pathway according to their priority. Data packet priority is consequently determined in a ring and a priority token attributed thereto. A high priority token ensures its data packet is switched into the transmission pathway when next available. Lower priority tokens are held by respective packets until all data packet priorities have been determined and no higher priority tokens attributed, whereupon the respective data packet is switched into the transmission pathway when next determined.
