    • The VIRTUAL WALLET CARD SELECTION APPARATUSES, METHODS AND SYSTEMS (“VWCS”) transform virtual wallet card selections by users utilizing mobile devices via VWCS components into virtual wallet card-based transaction purchase notifications. In one implementation, the VWCS obtains a user authentication request for a purchase transaction, and extracts a universal card account number from it. Upon querying a database, the VWCS determines that the user has access to a virtual wallet and obtains virtual wallet card selection options for the user from the database. The VWCS provides the virtual wallet card selection options to a user mobile device, and obtains a user selection of an account included among the options. The VWCS initiates a purchase transaction using the user selection. Also, upon completion of authorization of the purchase transaction, the VWCS provides a purchase receipt to the user mobile device.
    • 虚拟电子钱包卡选择设备,方法和系统(“VWCS”)将使用VWCS组件的移动设备的用户的虚拟钱包卡选择转换为基于虚拟钱包卡的交易采购通知。 在一个实现中,VWCS获得用于购买交易的用户认证请求,并从其中提取通用卡帐号。 在查询数据库时,VWCS确定用户可以访问虚拟钱包,并从数据库获取用户的虚拟钱包卡选择选项。 VWCS向用户移动设备提供虚拟钱包卡选择选项,并且获得包括在选项中的帐户的用户选择。 VWCS使用用户选择启动购买交易。 此外,在完成购买交易的授权之后,VWCS向用户移动设备提供购买单。

    • Effective bandwidth of a communication link is determined in a heterogeneous, packet switched network between a source and a destination, where effective bandwidth is defined as actual available bandwidth between the server and the client, minus the overhead of the various network protocols used to transmit the data. The method includes measuring transmission times between the source and a destination for a plurality data segments having different characteristics, such as different sized files or subfiles of data; processing the transmission times to cancel effects of transmission latencies other than the different characteristics of the data segments; and indicating a bandwidth based on said processing. The processing is done in parallel with the return of user resources to the destination, and using a bandwidth detection engine associated with a proxy server.
    • 在源和目的地之间的异构的分组交换网络中确定通信链路的有效带宽,其中有效带宽被定义为服务器和客户端之间的实际可用带宽,减去用于发送的各种网络协议的开销 数据。 该方法包括测量具有不同特征的多个数据段的源和目的地之间的传输时间,诸如不同大小的文件或子文件的数据; 处理传输时间以消除除了数据段的不同特性之外的传输延迟的影响; 并且基于所述处理指示带宽。 处理与用户资源返回到目的地并且使用与代理服务器相关联的带宽检测引擎并行完成。
