A wastewater plant’s Metro-E handoff is sub-rate to a CIR below line rate. Mid-day drops spike when the edge hard-polices bursts. Which behavior should they prefer at the civic edge?
Select an answer to reveal the explanation.
Short Explanation
Policing is a bouncer who cuts the line; shaping is a velvet rope that makes people wait their turn. On a sub-rate Metro-E circuit, shaping to CIR usually beats slamming drops at noon. Buffer and pace instead of discarding mid-burst.
Full Explanation
Policing drops or remarks traffic that exceeds a rate; shaping queues excess and emits at a configured rate. Toward a carrier CIR below physical speed, edge shaping often reduces unnecessary drops and improves TCP behavior versus hard policing. Ignoring QoS entirely leaves bursts unmanaged. Selectively policing only voice while ignoring bulk misses the sub-rate problem described.
