1. A network system comprising:

  • a plurality of network processor interfaces for transmitting and receiving data cell sequences,a switch fabric interface;

    an ingress path providing a plurality of ingress queues between the plurality of network processor interfaces and the switch fabric interface combining the transmitted data cells of the network processors to a single data cell sequence; and

    an egress path providing a plurality of egress queues and a memory controller between the plurality of the switch fabric interface and network processor interfaces for distributing data cell sequences from a received data cell sequence to the respective network processor interfaces, the egress path comprising a first egress path handling control signals and a second egress path handling data signals.
