Explanation
Traffic shaping is the mechanism that buffers excess traffic (traffic exceeding the configured rate) in a queue and then releases it later when bandwidth becomes available, rather than dropping it. This matches the requirement precisely: traffic still traverses the infrastructure but is delayed. Policing would drop or re-mark excess traffic rather than buffering it. Weighted Fair Queuing (WFQ) is a scheduling algorithm that fairly distributes bandwidth among flows but does not limit rates. IP Precedence and Per-Hop Behaviors (PHB) are traffic classification/marking mechanisms, not rate-control mechanisms.
