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.

摘要： Embodiments of the present invention are directed to a wildcard matching solution that uses a combination of static random access memories (SRAMs) and ternary content addressable memories (TCAMs) in a hybrid solution. In particular, the wildcard matching solution uses a plurality of SRAM pools for lookup and a spillover TCAM pool for unresolved hash conflicts.

摘要： Embodiments of the present invention relate to an architecture that extends counter life by provisioning each counter for an average case and handles overflow via an overflow FIFO and an interrupt to a process monitoring the counters. This architecture addresses a general optimization problem, which can be stated as, given N counters, for a certain CPU read interval T, of how to minimize the number of storage bits needed to store and operate these N counters. Equivalently, this general optimization problem can also be stated as, given N counters and a certain amount of storage bits, of how to optimize and increase CPU read interval T. This architecture extends the counter CPU read interval linearly with depth of the overflow FIFO.

摘要： A network switch comprises a plurality of packet processing units configured to process a received packet through multiple packet processing stages based on search result of a table. The network switch further comprises one or more memory units configured to maintain the table to be searched and provide the search result to the packet processing units. The network switch further comprises a table managing unit configured to accept a plurality of rules on bulk update to the table specified by a control unit, and perform the bulk update on the table based on the rules specified by the control unit without the control unit accessing the table directly for the bulk update.
