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
