Explanation

Caching engines (also called web caches or proxy caches) store copies of frequently requested web content (pages, images, files) locally on the network. When users request the same content again, the cache serves it directly without fetching it from the internet, reducing external bandwidth consumption and improving response times. Load balancing distributes traffic across multiple servers to prevent overload but does not locally store content. Traffic policing limits bandwidth usage by dropping or marking packets that exceed a defined rate. Traffic shaping controls the flow and priority of traffic but does not cache content locally. Only caching engines directly reduce bandwidth by serving content from local storage.
