Latest Patents

D Dean Casey holds a patent for an invention titled "Push-out of low priority signals from switch buffers." This invention provides an apparatus and method that ensures a high percentage of the highest priority input signals are accepted by the switch. By utilizing switch resources to remove lower priority input signals from the switch buffer, the invention accommodates higher priority input signals effectively. The apparatus requires a queue with simultaneous read and write capability, and it performs one read operation to N write operations, where N represents the number of input ports. The method pushes signals out of the buffer by executing additional 'dummy' read operations to read out signals of specified priority, subsequently discarding the signals to prevent them from entering the parallel-to-serial shift registers. A preferred embodiment of this invention employs an ATM CAM-controlled switch fabric, where the CAM receives the arrival number and priority of each cell in the buffer.
