摘要： An apparatus for routing data packets includes a network interface, a memory, a general purpose processor and a flow classifier. The memory stores a flow structure. Every packet in one flow has identical values for a set of data fields in the packet. The memory stores instruction that cause the processor to receive missing flow data and to add the missing flow to the flow structure. The apparatus forwards a packet based on the flow. The flow classifier determines a particular flow and whether it is already stored in the flow structure. If not, then the classifier determines whether that flow has already been sent to the processor as missing data. If not, then the classifier stores into a different data structure data that indicates the flow has been sent to the processor but is not yet included in the flow data structure, and sends missing data to the processor.

摘要： Techniques for routing a payload of a first network protocol, which includes header information for a second network protocol, include communicating a packet. In a circuit block, a first type for the first network protocol and a second type for the second network protocol are determined. The circuit block stores a classification that indicates a unique combination of the first type and the second type. A general purpose processor routes the packet based on the classification. Processor clock cycles are saved that would be consumed in determining the types. Furthermore, based on the classification, the processor can store an offset value for aligning the header relative to a cache line. The circuit block can store the packet shifted by the offset value. The processor can then retrieve from memory a single cache line to receive the header, thereby saving excess loading and ejecting of cache.

摘要： A system and method is provided for automatically identifying and removing malicious data packets, such as denial-of-service (DoS) packets, in an intermediate network node before the packets can be forwarded to a central processing unit (CPU) in the node. The CPU's processing bandwidth is therefore not consumed identifying and removing the malicious packets from the system memory. As such, processing of the malicious packets is essentially “off-loaded” from the CPU, thereby enabling the CPU to process non-malicious packets in a more efficient manner. Unlike prior implementations, the invention identifies malicious packets having complex encapsulations that can not be identified using traditional techniques, such as ternary content addressable memories (TCAM) or lookup tables.
摘要翻译： 提供了一种系统和方法，用于在分组可以转发到节点中的中央处理单元（CPU）之前自动识别和去除中间网络节点中的恶意数据分组，例如拒绝服务（DoS）分组。 因此，CPU的处理带宽不被识别并从系统内存中删除恶意数据包。 因此，恶意数据包的处理本质上从CPU中“卸载”，从而使CPU能够以更有效的方式处理非恶意数据包。 与先前的实现不同，本发明识别具有复杂封装的恶意数据包，这些封装不能使用诸如三进制内容可寻址存储器（TCAM）或查找表之类的传统技术来识别。

摘要： A pourer which may be used for concurrently pouring dark and white liqueurs from adjacent containers of a bottle. The pourer has a main pourer body with pourer body sections which is engagable, for example by snap fitting, with the respective container. Each pourer body section has a liquid passageway which extends from a liquid inlet to a pouring outlet. The liquid passageways include upstanding portions extending into the containers and separate upper bend portions leading to the outlets. The angle between the longitudinal axes of the outlets is approximately 120.degree. for concurrent pouring of the liquids to opposite sides of a glass. Separate air passageways extend from air inlet parts to air outlets. The air flow is controlled by an air pot over each outlet. The air pots are sized and positioned so that fluid does not enter the air passageways on pouring and only air is forced up the air passageways on finishing pouring.

摘要： A heat pipe roller includes a rotatable outer tube having a primary internal chamber for containing a fluid, a heater operable to heat the fluid and hence the tube, and a sensor. The sensor has a movable member which communicates with the primary chamber and is mounted on the tube for rotation therewith, and a fixed member situated in the region of the axis of rotation of the tube and so mounted relative to the tube that rotation of the tube does not rotate the fixed member. The fixed member is adapted to be connected to equipment for measuring an electrical characteristic of the sensor. The arrangement is such that, in use, the movable member moves in response to a temperature change or temperature related physical change in the primary chamber, thereby causing a corresponding change in the electrical characteristic of the sensor.

摘要： A self-encrypting drive (SED) comprises an SED controller and a nonvolatile storage medium (NVSM) responsive to the SED controller. The SED controller enables the SED to perform operations comprising: (a) receiving an encrypted media encryption key (eMEK) for a client; (b) decrypting the eMEK into an unencrypted media encryption key (MEK); (c) receiving a write request from the client, wherein the write request includes data to be stored and a key tag value associated with the MEK; (d) using the key tag value to select the MEK for the write request; (e) using the MEK for the write request to encrypt the data from the client; and (f) storing the encrypted data in a region of the NVSM allocated to the client. Other embodiments are described and claimed.

摘要： A digital dictation workflow system and method employing a plurality of client devices and at least one server. Certain client devices are operable to record audio information dictated by a user for storing as a digital audio file in a file store, and others are operable to receive and reproduce the stored digital audio file as audio. The server is connected to the client devices via a network, and manages storage and retrieval of the digital audio file to and from the file store and the client devices. The system and method further employ at least one database for storing dictation data pertaining to the digital audio file stored in the file store, and can be configured in a three-tier arrangement with the client devices being present in a presentation layer, the server present in a business logic layer, and the file store and database present in a data access layer.

摘要： Techniques for synchronizing use of buffer descriptors for data, such as packets transmitted over a network, include receiving private index data that indicates a particular buffer descriptor owned by a DMA controller, for moving data between a data port and a corresponding memory buffer. A write command is placed on a memory exchange queue to change the owner to a different processor and the private index data is incremented. A public index is determined, which indicates a different buffer descriptor in which the owner is most recently changed to the processor and is known to be visible to the processor. In response to receiving a request from the processor for the most recent buffer descriptor changed to processor ownership, the public index data is sent to the processor. Based on the public index data, the processor exchanges data with buffer descriptors guaranteed to be owned by the processor.
