1. A system for managing packets on a data network comprising;

  • a network node having one or more packet processors enabled to sort specific types of packets into categories for processing;

    a network access controller (NAC) operating in the node;

    a queue set for receiving processed packets from the NAC; and

    a CPU for pulling packets for processing from the queue set;

    wherein the packet processors provide enhanced security in the network by categorizing incoming packets destined for the CPU into three or more categories, being at least one category for packets received from known, trusted sources, one category for suspect sources, and one category for packets received from unsure sources and forwards the categorized packets to the queue set and the CPU pulls packets for processing from the queue set according to a priority listing of the categories.
