Abstract:
The invention relates to a process for the manufacture of optically pure (R) or (S)-5-(2-aminopropyl)-2-methoxybenzenesulfonamide with D-i.e. (2S, 3S) or L-i.e. (2R, 3R)-tartaric acid to form a mixture of diastereomeric salts, separating the diastereomeric salts by fractional crystallization in a mixture of solvent systems and at the specified temperature range and contacting the individual salts so separated with a base to provide said R-(−)-5-(2-aminopropyl)-2-methoxybenzenesulfonamide or S-(+)-5-(2-amino propyl)-2-methoxybenzenesulfonamide.
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:
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:
A storage system according to one embodiment for managing a first file includes a blob storage and a handler. The blob storage may be configured to store data related to the first file temporarily. The handler may be configured to store in the blob storage any data related to the first file and received from an application. The handler also may be configured to transfer at least a portion of the data from the blob storage to persistent storage in response to a commit instruction received from an application or generated by the handler. The handler also may be configured to retrieve any portion of the data stored in the blob storage and to send the same to a requesting application in response to an access request.

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.
