Packet counters and packet adders for traffic profiling in a multiprocessor router

摘要

A packet counter/adder for use in a multiprocessor system. The packet counter stores a counter value of data packets processed by a plurality of processors in the multiprocessor system. The packet counter comprises a first register capable of storing the counter value, wherein the counter value in the first register is incremented by a write operation to a first address associated with the first register. The counter value in the first register may be set to a specified value by a write operation to a second address associated with the first register.
