    Bursty traffic may cause network congestion. Traffic shaping regulates packets to be transmitted with a pre-configured data transmission rate using buffers (or queues). Your EMG2881-T20A uses the Token Bucket algorithm to allow a certain amount of large bursts while keeping a limit at the average rate.
