Network Design

An engineer must redesign Company XYZ's QoS strategy. The existing network is experiencing numerous packet drops because the guaranteed bandwidth allocated by the service provider is oversubscribed. Company XYZ requires a QoS strategy that controls traffic flow leaving the Edge router to reduce packet drops. Which QoS technique can be recommended as the solution?

  • A policing
  • B traffic shaping
  • C rate-limiting
  • D LLQ
Explanation

Traffic shaping regulates and smooths traffic leaving an interface to a configured rate that conforms to the service-provider bandwidth contract. Excess packets are queued for later transmission rather than immediately discarded, helping prevent congestion and minimize packet loss caused by egress-rate mismatch.
