Abstract:
A network device includes one or more sprayers, multiple packet processors, and one or more desprayers. The sprayers receive packets on at least one incoming packet stream and distribute the packets according to a load balancing scheme that balances the number of bytes of packet data that is given to each of the packet processors. The packet processors receive the packets from the sprayers and process the packets to determine routing information for the packets. The desprayers receive the processed packets from the packet processors and transmit the packets on at least one outgoing packet stream based on the routing information.
Abstract:
A key engine that performs route lookups for a plurality of keys may include a data processing portion configured to process one data item at a time and to request data when needed. A buffer may be configured to store a partial result from the data processing portion. A controller may be configured to load the partial result from the data processing portion into the buffer. The controller also may be configured to input another data item into the data processing portion for processing while requested data is obtained for a prior data item. A number of these key engines may be used by a routing unit to perform a large number of route lookups at the same time.
Abstract:
A smokeless tobacco formulation includes particles or pieces of tobacco, and may include other ingredients, such as salts, sweeteners, binders, colorants, pH adjusters, fillers, flavoring agents, disintegration aids, antioxidants, humectants, and preservatives. The moisture content of the particles of the tobacco may vary. Certain smokeless tobacco products have the form of tobacco compositions or formulations that result from casting or otherwise forming a slurry incorporating tobacco material and other components as a film or sheet. Certain smokeless tobacco products have the form of tobacco compositions or formulations that result from pressing, extruding or otherwise forming a mixture incorporating tobacco material and other components into a desired shape. The foregoing tobacco products, as well as snus-type products, can be packaged under conditions of controlled atmosphere. Smokeless tobacco products can be sealed in outer packaging materials that are virtually impervious to oxygen and/or moisture, and those packaging materials can be vacuum sealed or sealed such that the atmosphere therewithin is essentially inert.
Abstract:
Ordering logic ensures that data items being processed by a number of parallel processing units are unloaded from the processing units in the original per-flow order that the data items were loaded into the parallel processing units. The ordering logic includes a pointer memory, a tail vector, and a head vector. Through these three elements, the ordering logic keeps track of a number of “virtual queues” corresponding to the data flows. A round robin arbiter unloads data items from the processing units only when a data item is at the head of its virtual queue.
Abstract:
Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive material can be applied as a coating formulation in an off-line manner to a continuous paper sheet web that is later used for cigarette manufacture. The additive material can be applied as a coating formulation in an on-line manner to continuous paper web moving through an operating cigarette making machine. The coating formulation is applied to the paper web using roll applicator techniques, ink jet printing techniques or electrostatic precipitation techniques. Liquid coating formulation are curable, and are virtually absent of solvent or liquid carrier. Radiation, such as ultraviolet or electron beam radiation, is used to solidify and fix polymerizable liquid components of the coating formulation that have been applied to the paper web. Heating and subsequent cooling of the coating formulation used to fix solid components of the coating formulation that have been applied to the paper web. Registration techniques are used to ensure proper positioning of the additive material on the smokable rods so manufactured, and to ensure proper quality of those cigarettes.
