Class of Service

  • Enhanced host path traffic management for DDoS protection and CoS scheduling (PTX Series and QFX Series)—Enhanced host path traffic management offers improved distributed denial-of-service (DDoS) protection and class of service (CoS) scheduling for traffic directed towards the host CPU. Using the enhanced DDoS and CoS you can:

    • Prioritize the control traffic to prevent congestion on the host interface

    • Reshape bandwidth to evenly distribute the traffic and prevent host CPU overload

    • Implement queue-specific policing to ensure traffic fairness across multiple protocols sharing the same queue and prevent undesired effects due to excessive traffic.

    These enhancements result in more stable protocol operations and bolstered system security.
