Abstract: In one embodiment, a system includes a format block configured to receive a key, at least one rule, and rule formatting information. The rule can have one or more dimensions. The format block can be further configured to extract each of the dimensions from the at least one rule. The system can further include a plurality of dimension matching engines (DME). Each DME can be configured to receive the key and a corresponding formatted dimension, and process the key and the corresponding dimension for returning a match or nomatch. The system can further include a post processing block configured to analyze the matches or no matches returned from the DMEs and return a response based on the returned matches or nomatches.

Abstract: In one embodiment, a method includes encoding a key matching rule having at least one dimension by storing in a memory (i) a header of the key matching rule that has at least one header field, and (ii) at least one rule value field of the key matching rule corresponding to one of the dimensions.

Abstract: A Balanced Packet Transmit Opportunity (BPTO) mechanism allows balanced bandwidth traffic to be serviced while still maintaining the service levels desired for high priority traffic. The above embodiment achieved the result by distinguishing both queue types and slot style types, and performing selections differently depending upon the relative styles of the queues and slots. This arrangement provides a number of advantages. Because the selection method is fast and relatively simple to implement, a large number of queues may be integrated into the decision process while maintaining a desired output bandwidth. In addition, the selection process provides a flexibility, allowing multiple traffic shaping considerations to be modified during operations to support changing network requirements.
