What is the purpose of throttling in network management?

Throttling in network management is implemented primarily to control the flow of data and prevent the system from being overwhelmed during periods of high demand. When the capacity of a network is exceeded, throttling helps to manage the data traffic by reducing the volume of messages being transmitted, thereby ensuring that the overall performance and stability of the network are maintained. This is essential in preventing bottlenecks and ensuring that critical services remain functional, even under heavy load.

The other options touch on different aspects of network management but do not accurately describe the specific function of throttling. Increasing data flow during peak times would run counter to the purpose of throttling, which is about managing and reducing excessive load. While maintaining system security is crucial, it falls under different protocols and measures, not specifically throttling. Similarly, enhancing data encryption focuses on securing data rather than managing its flow and load within a network.
