Abstract:
A broadband switching system comprising:at least one ingress for connection to a respective signal source and at least one egress for connection to a selected signal receiving system; at least one switch for transmission information-carrying asynchronously transferred data cells carrying customer traffic from the ingress to the egress, system control means for accepting and establishing a communication channel between the ingress and the egress via the said switch, and bandwidth control means arranged to detect data cells received at the ingress for transmission along said communications channel, and, automatically in response to such cell detection, to cause the system control means to increase the bandwidth allocated to said channel to a level sufficient to permit transmission of a predetermined number of cells within a predetermined time period; said bandwidth control including feedback means arranged to transmit a maximum output cell rate signal back to the signal source indicating a cell rate which is a function of the allocated bandwidth.
