  • Cell copy count
    Patent number: 8599694
    Abstract: The present invention is directed to a network device, method and apparatus for processing data. The present invention includes at least one ingress module for performing switching functions on incoming data. The invention further includes a memory management unit (MMU) for storing the incoming data, and at least one egress module for transmitting the incoming data to at least one egress port. Further, in the present invention, the memory management unit further comprises a cell copy count pool (CCP) memory, wherein the CCP determines when a memory cell can be made available.
