hog-violator-show

The CPU Control Packet Processing Protection feature allows the CPU control packet processing path be protected against misbehaving and malicious hosts or end-points that may flood control protocol packets. This is also called “CPU hog protection”.

Netvisor provides three types of Control Plane Protection:

  • Overall CPU Bandwidth
  • Dedicated Queues for Critical Flows
  • Protection from offending flows in Critical Queues (DDOS Protection) by using special CPU hog queues
