摘要： A method, system and computer program product for eliminating memory corruption when performing multi-threaded tree operations. A network processor may receive a command to perform a tree operation on a tree on one or more of multiple threads. Upon performing the requested tree operation, the network processor may lock one or more resources during a portion of the execution of the requested tree operation using one or more semaphores. A semaphore may refer to a flag used to indicate whether to “lock” or make available the resource associated with the semaphore. Locking may refer to preventing the resource from being available to other threads. Hence, by locking one or more resources during a portion of the tree operation, memory corruption may be eliminated in a multiple thread system while preventing these resources from being used by other threads for a minimal amount of time.
摘要翻译：一种用于在执行多线程树操作时消除内存损坏的方法，系统和计算机程序产品。网络处理器可以在多个线程中的一个或多个上接收在树上执行树操作的命令。在执行所请求的树操作时，网络处理器可以在使用一个或多个信号量的所请求的树操作的执行的一部分期间锁定一个或多个资源。信号量可以指用于指示是否“锁定”或提供与信号量相关联的资源的标志。锁定可能是指防止资源对其他线程可用。因此，通过在树操作的一部分期间锁定一个或多个资源，可以在多线程系统中消除内存损坏，同时防止这些资源在最短时间内被其他线程使用。

摘要： A system and method for controlling overall behavior of a network processor device implemented in a network processing environment servicing a communications network. The method includes steps of receiving a guided control frame including one or more control functions for configuring various functional devices within the network processor with device control parameter data; a step of forwarding one or more control functions from a received control frame to a functional device within the network processor to be configured; and, executing the control functions as specified in the control frame. A novel control frame data structure and communications infrastructure is implemented whereby any network processor device operating in a distributed network processing environment may be controlled in accordance with executed control functions and device control parameter data.

摘要： Assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device is provided. In a given processing period, a source is selected in a manner that maintains fairness in the selection process. A corresponding sink is selected for the selected source based on processing efficiency. If, due to assignment constraints, no sink is available for the selected source, the selected source is retained for selection in the next scheduling period, to maintain fairness. In this case, to optimize efficiency, a most efficient currently available sink is identified and a source for providing work to that sink is selected.

摘要： A method and system for reducing the lookup time in packet forwarding on computer networks. A first lookup is performed in a memory tree to find a first protocol forwarding entry in the memory tree. The forwarding entry includes first protocol (e.g., EGP) information and cached associated second protocol (e.g., IGP) information. Both EGP and IGP information are retrievable with the first lookup and used in the determination of an EGP route for the data packet. If the cached IGP information has been invalidated due to address updates, a second lookup can be performed to find an original IGP entry in the memory tree, the information from which can be cached in the EGP forwarding entry if a background maintenance task has finished designating all the EGP entries as having out-of-date caches.

摘要： Apparatus for providing a checksum in a network transmission. In one aspect of the invention, a checksum for a packet to be transmitted on a network is determined by retrieving packet information from a storage device, the packet information to be included in the packet to be transmitted. A blind checksum value is determined based on the retrieved packet information, and the blind checksum value is adjusted to a protocol checksum based on descriptor information describing the structure of the packet. The protocol checksum is inserted in the packet before the packet is transmitted.
