ABSTRACT:
A method of bandwidth management for ensuring a guaranteed bandwidth to each station of a transmission network (18) comprising a plurality of stations (10, 12, 14, 16), forming a logical ring wherein one of the stations is the ring manager and wherein a token frame is circulating along the logical ring from station to station, each station being allowed to transmit data to other stations over the transmission network when it receives the token frame while holding the token during the time the station is transmitting data. A credit of data bytes allowed to be transmitted is allocated to each station upon reception of the token frame when an Utilization Rate based upon the number of data bytes sent by all stations since the preceding reception of the token frame is greater than a predetermined threshold.
