摘要： A method and apparatus for buffering data units in a communication switch that allows for configurable monitoring of the buffer contents is presented. Such an apparatus includes a context table that stores a plurality of independent group identifiers for each connection. Although the group identifiers may include a partition group identifier and a loss group identifier that is dependent on the partition group identifier, additional group identifiers are included in the context table for each connection that are independent of other group identifiers in the context table. Such a context table may be dynamically reconfigured in order to group connections for buffer monitoring operations related to congestion detection, traffic shaping, and data admission with respect to buffering. When a data unit is received corresponding to a particular connection, the context table is referenced to retrieve the set of group identifiers corresponding to that connection. As a cell is stored in the buffer, count values corresponding to at least some of the group identifiers included in the set of group identifiers for that connection are incremented. Similarly, when data is dequeued from the buffer for forwarding, the set of group identifiers for that particular data unit is determined and the counters corresponding to at least some of those groups are decremented. As such, the count value corresponding to each of the groups can be referenced to determine the number of data units corresponding to that group that are currently stored within the buffer.

摘要： One or more embodiments of the present invention provide a method and apparatus for efficiently accessing data segments having arbitrary alignment with the memory structure in which they are stored. For example, a memory structure may be organized so that memory accesses occur with respect to units of memory defined based on a relationship of a total memory bandwidth to a size of an amount of desired data to be accessed. In such an example, the units of memory are defined so as to maximize efficiency by minimizing the number of memory access operations performed to access the amount of desired data.

摘要： A method and apparatus for frame-aware and pipelined hierarchical scheduling is described. In accordance with at least one embodiment of the invention, some or all schedulers of a communication node are associated with one or more storage devices that maintain values used by corresponding higher level schedulers to make scheduling decisions. Because of the nature of the scheduling decision flow and the potential to update registers in real-time, the scheduling arrangement can respond almost immediately to changes occurring at the input queues, which allows scheduling to be responsive to differing priorities of incoming cells. The nature of the scheduling decision flow also allows pipelined scheduling, in which scheduling of one or more additional cells can begin before scheduling of a first cell is completed.

摘要： A fast and scalable pattern making engine is presented. The engine represents variations on a Shift-And method capable of matching patterns in data streams having high speed data rates. In one aspect of the invention high speed is achieved by accessing the pattern RAM in parallel. In another aspect, the input is likened to TDM and individual slots or channels are accessed separately. The two aspects can also be combined to provide a scalable and high speed pattern matching engine. The engine is adaptable to streams of known length or more complex expressions such as regular expressions with arbitrary length.

摘要： In accordance with one or more embodiments of the present invention, a method and system for providing combined processing of cell traffic and packet traffic is described. For a communication device, the improved system provides a series of inputs on a single line card for processing both ATM traffic (e.g., native ATM or encapsulated packets) and packet traffic. The system receives the cell traffic and packet traffic, then converts them into a common form. The converted traffic traverses the fabric, then the system reconstitutes the converted traffic into its original form. The system provides output as ATM traffic or packet traffic, as originally received.

摘要： One or more embodiments of the present invention provide a method and apparatus for multicasting of data, for example, cell data or frame data, with the ability to dynamically manage such multicasting. A data structure, referred to as a to-do list, is maintained with entries for enqueued data elements. To-do list entries include a data element pointer identifying the corresponding data element and a leaf to be processed pointer indicating the progression of transmission of the corresponding data element to the plurality of leaves of a multicast tree, wherein the plurality of leaves are used to transmit the data to a plurality of multicast destinations. A method for counting copies of each data element as they are transmitted to each of the plurality of leaves is performed so as to accommodate the addition or deletion of one or more multicast leaves during the multicasting process.
