ATM DYNAMIC CONNECTION BANDWIDTH CONTROL

摘要

An apparatus for changing bandwidth loading by a bandwidth change amount in a communications interface having elastic and non-elastic call connections where the elastic and non-elastic call connections have associated current cell rates and equivalent cell rates respectively. The apparatus includes a processor programmed to determine whether the bandwidth change amount is negative or positive. When the bandwidth change amount is negative the processor reduces the current cell rate of each elastic connection and releases at least some non-elastic connections such that the current cell rate of each elastic connection is reduced and the non-elastic connections are released until the total of the current cell rates of the elastic connections and the equivalent cell rates of the non-elastic connections have been reduced by at least the bandwidth change amount. When the bandwidth change amount is positive, the processor increase the current cell rate of each elastic connection and restores non-elastic connections.
