To prevent packet loss while ensuring that outbound traffic adheres to a specified bandwidth limit by storing excess packets and sending them later, which QoS mechanism should be implemented?
Traffic Policing
Classification
Traffic Shaping
Weighted Fair Queuing (WFQ)
Traffic Shaping is the QoS mechanism that adjusts the outbound traffic flow by buffering excess packets that exceed the configured bandwidth limit and transmitting them when the bandwidth becomes available. This prevents packet loss and smooths out traffic bursts. Traffic Policing, in contrast, drops or remarks packets that exceed the bandwidth limit, which can lead to packet loss. Weighted Fair Queuing (WFQ) is a scheduling algorithm that allocates bandwidth fairly among flows but doesn't specifically store excess packets for later transmission. Classification involves identifying and grouping traffic types for QoS policies but doesn't control bandwidth or prevent packet loss.
