Abstract
A method of bandwidth management enabling to insure a guaranteed bandwidth to each station of transmission network comprising a plurality of stations () forming a logical ring wherein a token frame is circulating from station to station, each station being allowed to transmit a credit (c) of data bytes upon reception of the token frame wherein the credit is increased in proportion to a variable TRTT standing for Token Round Trip Time which is the time taken for the token frame to circulate around the logical ring since the preceding reception of the token frame by the station. The credit is increased in proportion of a variable CIR standing for Committed Information Rate which is the guaranteed transmission rate that the station can use to transmit data wherein the value of CIR is determined by a class of bandwidth which has been previously selected by the station upon the preceding reception of the token frame by the station.
