Abstract:
A trunk line bandwidth reservation system for an asynchronous transfer mode switching system which is coupled to a plurality of terminals, said trunk line bandwidth reservation system comprising:data storage means, having an input and an output, for receiving and storing reservation data and outputting reservation data when accessed; bandwidth reservation means, coupled to the output of said data storage means, for registering reservation datum which includes at least a time zone and a reserved bandwidth to be used by a reserved communication into said data storage means in response to a reservation request which includes the reservation datum and is generated from a first terminal before the time zone, said time zone starting from a reserved start time; and bandwidth assignment means, coupled to said bandwidth reservation means, for assigning the reserved bandwidth to the first terminal in response to a connect request which is generated from the first terminal at the reserved start time, and for assigning an available bandwidth to a second terminal in response to a connect request which is generated from the second terminal by judging the available bandwidth based on a bandwidth which is presently in use and the reserved bandwidth which is secured by the reservation datum accessed from said data storage means, said second terminal being other than the first terminal and the connect request generated by said second terminal is not associated with said reservation request or another reservation request and wherein, said data storage means, said bandwidth reservation means and said bandwidth assignment means are provided within the asynchronous transfer mode system.
