POLICER ARCHITECTURE

摘要

A policer system on one or more place and/or route blocks. The policer system including a plurality of local physical policers each stored in a plurality of physical memory banks and coupled with a plurality of global policers stored in one or more global banks separate from the physical banks. Thus, each bank of the global policers are able to represent a logical combination of a plurality of the physical banks of physical policers.

1. A traffic policer system for policing traffic, the system comprising:
a plurality of physical memory banks each storing a plurality of physical policers; a global memory bank storing a plurality of global policers, wherein each of the global policers is associated with a different one of the physical policers in each of the physical memory banks; and a scheduler element coupled with the physical memory banks and the global memory bank, wherein the scheduler element performs a local synchronization that synchronizes a state of one of the physical policers of one of the physical memory banks with a state of the associated global policer during a cycle.
