  • Publication number: 20210264389
    Abstract: A computing system has a communication interface for receiving, from a gift bag wallet application operating on a cardholder mobile device, a transfer request to transfer a balance of a prepaid payment card to a cardholder account associated with a cardholder digital wallet. A processor of the mobile device is programmed to determine, from the transfer request, the prepaid payment card issuer and a payment network associated with the prepaid payment card. Using the communication interface, the system transmits, to the prepaid payment card issuer, a balance request message for a balance of the prepaid payment card and receives a balance request response message identifying the balance of the prepaid payment card. The system then transfers the balance of the prepaid payment card from the prepaid payment card issuer to the cardholder account associated with the cardholder digital wallet based on cardholder information of the cardholder account included in the transfer request.

  • Publication number: 20210117425
    Abstract: Systems and methods are described for establishing and managing components of a distributed computing framework implemented in a data intake and query system. The distributed computing framework may include a master and a plurality of worker nodes. The master may selectively operate on a search head captain that is chosen from the search heads of the data intake and query system. The search head captain may distribute configuration information for the master and the distributed computing framework to the other search heads, which in turn, may distribute that configuration information to indexers of the data intake and query system. Worker nodes may be selectively activated for operation on the indexers based on the configuration information, and the worker nodes may additionally use the configuration information to contact the master and join the distributed computing framework.

  • Patent number: 8099571
    Abstract: Bandwidth consumption between a data replication source and destination and storage consumption at the destination are reduced, when logical block mirroring is used with source deduplication, by eliminating repeated transmission of data blocks from source to destination. A reference is created for each data block at the source, the reference being unique within a storage aggregate of the source. During a mirror update, the source initially sends only the references of modified data blocks to the destination. The destination compares those references against a data structure to determine whether the destination already has any of those data blocks stored. If the destination determines that it already has a data block stored, it does not request or receive that data block again from the source. Only if the destination determines that it has not yet received the referenced data block does it request and receive that data block from the source.

  • Patent number: 7924733
    Abstract: Performance problems or other conditions are analyzed in a system comprising a plurality of endpoint devices and an associated centralized or distributed controller. End-to-end measurements are obtained for respective paths through the network, for example, using communications between the endpoint devices. For a given end-to-end measurement obtained for a particular one of the paths, a value of a performance indicator for the path is determined and the performance indicator value is assigned to each of a plurality of links of the path. The determining and assigning operations are repeated for additional ones of the end-to-end measurements, the links are grouped into one or more exculpation or inculpation sets based on how many times a particular performance indicator value has been assigned to each of the links, and the one or more sets are utilized to determine, for example, the location of a performance problem in the network.

  • Patent number: 7768929
    Abstract: A network monitoring and analysis system is configured to conduct performance analysis on a network using a plurality of endpoint devices. Locations of respective endpoint devices for use in the performance analysis of the network are determined utilizing an algorithm which characterizes the network as a graph having edges and vertices and associates endpoint devices with particular ones of the vertices in an iterative manner based on impact of said vertices on achievement of a specified coverage criterion. The coverage criterion may comprise a links-covered criterion which specifies a percentage of a total number of links of the network that are covered by test communications. As another example, the coverage criterion may comprise a links-estimable criterion which specifies a percentage of a total number of links of the network for which performance is estimable from collected end-to-end path measurement data.
