    Abstract: A system and method can support dynamic provisioning in a network switch environment, such as supporting virtualized switch classification tables in a network switch. The system can provide a plurality of memory blocks that can be used to build one or more classification tables for supporting packet processing. Furthermore, the system can comprise a management entity that operates to monitor traffic profile associated with a network port in the network switch. Then, the management entity can allocate one or more memory blocks in the plurality of memory blocks for a logical classification table, and associate the logical classification table with the network port.

    Abstract: A system and method can support efficient packet switching in a network environment. A networking device, such as a network switch, which includes a crossbar fabric, can be associated with a plurality of input ports and a plurality of output ports. Furthermore, the networking device operates to detect a link state change at an output port on the networking device. The output port can provide one or more credits to an output scheduler, and the output scheduler allows one or more packets targeting the output port to be dequeued from one or more virtual output queues, based on the one or more credits.

    Abstract: Implementations of the present disclosure involve an apparatus and/or method for an efficient packet queue depth sorting scheme for a ‘longest queue first’ based switch fabric device. In general, the sorting scheme compares a data queue length on an incoming port to a sorted queue of available ports based on longest queue. Based at least on the results of the comparison of the data queue length on the input port, a port designator is inserted into a re-sorted longest queue available port list in the proper position based on the incoming or outgoing port data length. The remaining entries are then sorted around the inserted port designator. Because the comparison and insertion of the port designator can occur in one clock cycle of the switch fabric device, efficiency of the switch is improved.

    Abstract translation: 本公开的实现涉及用于基于“最长队列第一”的交换矩阵设备的有效分组队列深度排序方案的装置和/或方法。 一般来说，排序方案将输入端口上的数据队列长度与基于最长队列的可用端口排序队列进行比较。 至少基于输入端口上的数据队列长度的比较结果，基于输入或输出端口数据长度，将端口指示符插入到适当位置的重新排序的最长队列可用端口列表中。 然后，其余条目围绕插入的端口指示符进行排序。 因为端口指示符的比较和插入可以在交换结构设备的一个时钟周期内发生，所以提高了交换机的效率。

    Abstract: An apparatus that recursively classifies packets includes a hierarchical set of classification engines that perform parallel classification of the packets in a packet processing queue. In particular, a first classification engine separates the packets based on physical-layer information and/or link-layer information in the packets. Then, second classification engines further separate the packets into multiple parallel pipelines based on layer information in the packets that is other than the physical-layer information and the link-layer information. The first classification engine and the second classification engines maintain a relative ordering of the packets in network sub-flows while allowing changes in relative ordering among different network flows.
