摘要： A method and system for transmitting packets in a packet switching network. Packets received by a packet processor may be prioritized based on the urgency to process them. Packets that are urgent to be processed may be referred to as real-time packets. Packets that are not urgent to be processed may be referred to as non-real-time packets. Real-time packets have a higher priority to be processed than non-real-time packets. A real-time packet may either be discarded or transmitted into a real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time queue congestion conditions. A non-real-time packet may either be discarded or transmitted into a non-real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time and non-real-time queue congestion conditions.

摘要： A procedure is used to provide data structures that handle large numbers of active data entries and a high rate of additions and deletions of active entries. The procedure utilizes one or more of the following modifications. Timers are removed from individual session table entries and are linked via pointers. Bilateral links are established between the session table and the timer structure. Aging/timer checks are applied to the timer control block (TCB). A chain of TCBs, optionally including an excess of blocks, may be used along with packing of multiple TCBs into a single memory location. This excess of blocks permits a terminated session to continue to occupy a TCB until the timer process progresses to that block location in the chain of blocks.

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： The invention relates to a switching device which transports data packets from input ports to selected output ports. The payload of the packets is stored in a storage means. A switching means is arranged which has more switch outputs than switch inputs and which switches sequentially between one switch input and several switch outputs while storing the payloads. Furthermore, the invention relates to a storing method which uses switching means to store payloads in a sequential order and to a switching apparatus comprising several switching devices. Furthermore, the invention relates to systems using the switching device as a scaleable module.

摘要： The present invention relates to the management of a large and fast memory. The memory is logically subdivided into several smaller parts called buffers. A buffer-control memory (11) having as many sections for buffer-control records as buffers exist is employed together with a buffer manager (12). The buffer manager (12) organizes and controls the buffers by keeping the corresponding buffer-control records in linked lists. A request manager (20), as pad of the buffer manager (12), does or does not grant the allocation of a buffer. A stack manager (21) controls the free buffers by keeping the buffer-control records in a stack (23.1), and a FIFO manager (22) keeps the buffer-control records of allocated buffers in FIFO linked lists (23.2-23.n). The stack and FIFO managers (20), (21) are parts of the buffer manager (12), too.
