What is the purpose of traffic shaping?

Traffic shaping is a quality of service (QoS) mechanism that delays certain packets to conform to a desired traffic rate. Its primary purpose is to limit bandwidth usage by smoothing out traffic bursts and ensuring that data transmission adheres to a predefined rate, preventing network congestion and ensuring fair access. This is different from policy-based routing, which directs traffic based on defined policies rather than bandwidth limits. Dynamic flow identification is a broader concept related to recognizing traffic patterns, not directly shaping them. While traffic shaping can be part of a QoS strategy, it doesn't provide best-effort service; instead, it actively manages and limits traffic to meet specific performance goals.
