Broadband input buffered atm switch

Abstract From the Canadian patent

Broadband ATM switches for switching ATM packetized data in timeslots are disclosed In one embodiment the switch, includes input buffer means a space switch for connecting input ports and output ports at successive timeslots and a system scheduler. The timeslot utilization processing is carried out by using a contained addressable memory. A bit map is provided for registering the timeslot utilization of the input ports and the output ports. An encoder means determines the earliest commonly available timeslot for connecting input ports and their requested output ports. There is further disclosed an architecture in which groups of input ports share common buffer memories and in which the …
