摘要： A network device includes an interface and packet processing logic. The interface receives a multicast packet. The packet processing logic determines identifier data corresponding to the received multicast packet and replicates the identifier data to multiple outgoing packet forward engines at a first point in a processing path. The packet processing logic further replicates the identifier data to multiple data streams at a second point in the processing path and replicates the identifier data to multiple logical interfaces in the same stream at a third point in the processing path.
摘要翻译：网络设备包括接口和分组处理逻辑。接口收到组播报文。分组处理逻辑确定与所接收的多播分组相对应的标识符数据，并且在处理路径的第一点将标识符数据复制到多个输出分组转发引擎。分组处理逻辑还将标识符数据复制到处理路径中的第二点处的多个数据流，并且在处理路径中的第三点将标识符数据复制到同一流中的多个逻辑接口。

摘要： A network device constructs a notification corresponding to a received multicast data unit, where the notification includes administrative data associated with the multicast data unit that does not include a payload of the multicast data unit. The network device replicates the notification at least three different processing elements at different locations in a processing path of the network device to produce multiple replicated data items and produces a copy of the multicast data unit for each of replicated notifications. The network device forwards each copy of the multicast data unit towards a multicast destination.
摘要翻译：网络设备构建对应于所接收的多播数据单元的通知，其中通知包括与不包括多播数据单元的有效载荷的多播数据单元相关联的管理数据。网络设备在网络设备的处理路径中的不同位置处至少复制三个不同的处理元件，以产生多个复制数据项，并为每个复制的通知产生多播数据单元的副本。网络设备将组播数据单元的每个副本转发到组播目的地。

摘要： A packet scheduler is configured to perform quality of service (QoS) scheduling on a per-data unit basis. A downstream processing engine is operatively connected to the packet scheduler for receiving forwarded packets. A feedback path is operatively connected between the downstream processing engine and the packet scheduler for transmitting a net data unit change value reflecting a change in packet size between an output of the packet scheduler and an output of the downstream processing engine.

摘要： A method for generating code for an object-oriented processor is disclosed. An instruction table is initialized to include a plurality of instructions for an object-oriented processor, each of the plurality of instructions having a set of operands and an operand type for each of the set of operands. In addition, a weighting table is initialized to include a set of the plurality of instructions and a weight for each of the set of the plurality of instructions, the weight indicating frequency of generation for a particular instruction. A class hierarchy is created, the class hierarchy having a plurality of classes stored in a tree data structure, each of the plurality of classes having a set of fields and a set of methods, each of the plurality of classes, each of the set of fields, and each of the set of methods having object-oriented properties. Within the class hierarchy, a set of objects is randomly generated for each of the plurality of classes. A method is selected from the sets of methods, and a set of instructions is generated for the selected method according to the instruction table and the weighting table using the class hierarchy.
