Traffic Shaping is a technique for managing congestion on a network by delaying the flow of less important/desired packets on the network so more valuable/desirables ones are able to pass. Traffic shaping reduces traffic by preventing certain undesirable traffic from entering the network as well as limiting the amount of certain undesirable traffic entering the network.
