摘要： A method and systems for dynamically distributing packet flows over multiple network processing means and recombining packet flows after processing while keeping packet order even for traffic wherein an individual flow exceeds the performance capabilities of a single network processing means is disclosed. After incoming packets have been analyzed to identify the flow the packets are parts of, the sequenced load balancer of the invention dynamically distributes packets to the connected independent network processors. A balance history is created per flow and updated each time a packet of the flow is received and/or transmitted. Each balance history memorizes, in time order, the identifier of network processor having handled packets of the flow and the associated number of processed packets. Processed packets are then transmitted back to a high-speed link or memorized to be transmitted back to the high-speed link later, depending upon the current status of the balance history.
摘要翻译：一种用于在多个网络处理装置上动态地分发分组流的方法和系统，并且在处理之后重新组合分组流，同时保持分组顺序，即使对于单个流超过单个网络处理装置的性能的流量也是如此。在分析了输入数据包以识别数据包是流量的一部分后，本发明的顺序负载平衡器动态地将分组分发到连接的独立网络处理器。每个流创建一个平衡历史，并在每次接收和/或发送流的数据包时进行更新。每个平衡历史按时间顺序记录已处理流的分组的处理器的数据包的标识符和相关联的处理数据包的数量。处理的数据包然后被发送回到高速链路或存储，以根据当前的平衡历史状态稍后传送回高速链路。

摘要： A method and system for reducing arbitration latency employs speculative transmission (STX) without prior arbitration in combination with routing fabric scheduled arbitration. Packets are sent from source locations to a routing fabric through scheduled arbitration, and also through speculative arbitration, to non-contentiously allocate outputs that were not previously reserved in the routing fabric to the speculatively transmitted packets.

摘要： For switching or transmitting data packets, one can provide communication systems which consist of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master (21), the others are slave modules (22) controlled by control signals (25) derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.
摘要翻译：对于切换或传输数据分组，可以提供由多个模块组成的通信系统 - 在分组的分段上并行操作 - 以提高速度和处理能力。一个模块作为主机（21），其他模块是由主模块导出的控制信号（25）控制的从模块（22）。重要的是，在每个模块中，数据段和每个分组的相应控制信号被正确同步，因为在大系统中，承载分组段和控制信号路径的数据路径可能具有显着不同的延迟。本发明提供了传播延迟差的测量和用于在每个从模块中引入受控延迟，使得数据段和控制信号可以通过延迟其中一个或另一个来正确地相关。同步数据包除正常数据包之外传输，用于获取用于确定延迟差的时间戳。

摘要： Disclosed is a method for validating a data packet by a network processor supporting a first-network protocol and a second network protocol and utilizing shared hardware. The network processor receives a data packet; identifies a network packet protocol for the data packet; and processes the data packet according to the network packet protocol comprising: updating a first register with a first partial packet length specific to the first network protocol; updating a second register with a second partial packet length specific to the second network protocol; and updating a third register with a first checksum computed from fields independent of the network protocol. The method produces a second checksum utilizing a function that combines values from the first register, the second register, and the third register. The method validates the data packet by comparing the data packet checksum to the second checksum.
