US Patent 11539628 Automated configuration of policer parameters

Embodiments of the present disclosure automatically set a maximum burst size in a policer to optimize the flow of traffic in a network. In one embodiment, a method includes receiving a policer rate set by a first policy, a maximum rate corresponding to one or more communications channels, and maximum burst time for performing at data burst. A maximum burst size is determined automatically based on the received policer rate, maximum rate, and maximum burst time. A policer in a network device is configured to limit traffic received at the one or more communications channels based on the maximum burst size.
