Abstract
In a network node having one or more packet processors and at least one CPU required to process specific types of packets, a system for managing the specific types of packets for CPU processing has one or more packet processors enabled to sort the specific types of packets into two or more categories of different priority for processing; and a queue set for queuing the sorted packets according to priority ahead of the CPU. The system is characterized in that the CPU processes the queued packets according to priority. In a special case the queues are a part of network access controller (NAC). Also in some cases a software component is provided for configuring the hardware.
