Match each Quality of Service (QoS) mechanism or Per-Hop Behavior (PHB) on the left to its corresponding operational characteristic or header specification on the right.
- Expedited Forwarding (EF)Uses DSCP decimal 46 (binary 010110) to designate low-loss, low-latency, low-jitter traffic typically placed in a Strict Priority Queue.
- Assured Forwarding 41 (AF41)Uses DSCP decimal 34 (binary 100010) to designate Class 4 traffic with low drop probability.
- Traffic PolicingMonitors traffic rate against a configured limit and immediately drops or remarks excess traffic without queuing it.
- Traffic ShapingSmooths outbound traffic bursts by buffering excess packets in memory and releasing them at a steady rate.
Cevap
Expedited Forwarding matches DSCP decimal 46 / Strict Priority Queue service; Assured Forwarding 41 matches DSCP decimal 34 / Class 4 low drop probability; Traffic Policing matches immediately dropping or remarking excess traffic without queuing; Traffic Shaping matches buffering excess traffic to smooth bursty egress rates.
Expedited Forwarding (EF) is standard DSCP 46 (010110) intended for real-time traffic requiring low latency/jitter via priority queuing. Assured Forwarding 41 (AF41) corresponds to DSCP 34 (100010) offering Class 4 high-priority bandwidth with a low drop probability. Traffic Policing measures rate limits and drops or remarks exceeding traffic immediately. Traffic Shaping regulates egress rate spikes by holding overflow packets in memory buffers.
