Packet shaping is a network management technique that controls the flow of data packets across a network. By prioritizing certain types of traffic, such as video streaming or online gaming, it ensures that these applications receive the necessary bandwidth for optimal performance. This helps to prevent congestion and maintain a smooth user experience. Network administrators use packet shaping to allocate resources effectively, especially during peak usage times. By analyzing traffic patterns, they can apply rules that limit or enhance specific data flows, ensuring that critical services remain accessible while less important traffic is managed accordingly.
