  • Publication number: 20140304093
    Abstract: The present disclosure is directed towards small modules, web plugins, which may be placed on any influential content which simplify and promote sales by operating as a social sales point (SSP). SSP's simplify sales by avoiding buyers engaging in any further searches or product comparisons. The sales process is promoted and supported by the inherent trust and revere placed upon the content owner, with the influential content providing a framework to complete the transaction and close the sale. Additionally, SSP promotes sales by keeping track of the reward of referrers, and provide a fair way of sharing reward with this social middle man. SSP allows simple proliferation, so that any effective promotion will quickly spread to its maximum by the power of social media.

  • Publication number: 20140188822
    Abstract: The efficiency of data de-duplication may be improved by storing related file data in a single container, or in multiple linked containers, of a history. Additionally, the efficiency of data de-duplication may be improved when shorter hash tables are used to reference historical data in a history. Shorter hash tables may be achieved by storing fewer than all the hash values obtained for a given amount of historical data. Further, the efficiency of data de-duplication may be improved by comparing related incoming file data with historical data from a container without hashing/chunking the remaining file data upon matching an earlier chunk of the incoming file data to the container.

  • Publication number: 20140189134
    Abstract: System and method embodiments are provided herein to test Network Attached Storage (NAS) server performance by generating a sufficient load in NAS client sessions. A test device is configured to run as many needed NAS clients to generate enough NAS session load for evaluating the NAS server performance. An embodiment comprises a method for testing a NAS server comprising starting a NAS client, establishing a session between the NAS client and the NAS server, exchanging communications for the session at a network stack layer below the NAS client, terminating the NAS client, starting a second NAS client, establishing a subsequent session between the second NAS client and the NAS server, exchanging communications for the subsequent session at the network stack layer while exchanging communications for the session, and terminating the second NAS client.
