Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, and include a method for managing and processing receipt information including identifying a user associated with a transaction; receiving a receipt for the transaction from a merchant system or a payment source used to fund the transaction; logging the receipt in a database associated with the user; providing an acknowledgement to an entity associated with the transaction and providing a notification of the transaction to a device associated with the user.

Automatic receipt logging and notifications for transactions

Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, and include a method for fraud prevention. A method includes receiving registration information for a user, including identities of the user and an authenticating device and a payment source identifier, and storing the registration information. A payment authorization request relating to a transaction purported to be by the user and including the payment source identifier is received. Using the payment source identifier, the identity of the user and the authenticating device is retrieved. A communication is provided to the user including transaction information. The message is delivered to the user at the authenticating device. The method also includes receiving (and subsequently forwarding) either a payment authorization or a payment repudiation responsive to the communication from the user by way of the authenticating device.

Methods and apparatus are provided for virtualizing resources including peripheral components and peripheral interfaces. Peripheral component such as hardware accelerators and peripheral interfaces such as port adapters are offloaded from individual servers onto a resource virtualization switch. Multiple servers are connected to the resource virtualization switch over an I/O bus fabric such as PCI Express or PCI-AS. The resource virtualization switch allows efficient access, sharing, management, and allocation of resources.

A bandwidth divider and method for allocating bandwidth between a plurality of packet processors. The bandwidth divider includes a plurality of counters for measuring the bandwidth of data packets transferred from the bandwidth divider to a respective packet processor; and a controller for analyzing the plurality of counters and transferring a data packet to a selected packet processor based on the contents of the counters. The method monitors the bandwidth consumed by the packet processors; determines, based on the bandwidth consumed by the packet processors, which packet processor has consumed the least amount of bandwidth; and allocates a next data packet to the packet processor which has consumed the least amount of bandwidth.

Bandwidth division for packet processing

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.

Preserving the order of packets through a device

A network device, such as a router, utilizes a virtual interface to hide the presence of redundant backup physical interfaces from a router control unit. If traffic needs to be redirected from a primary physical interface, the router remaps the virtual interface to the backup physical interface without needing to update routes and select one or more alternative routes due to the need to redirect traffic. Instead, the router control unit redirects network traffic associated with the primary physical interface to the associated backup physical interface. In this manner, delays associated with route updating can be avoided, and a relatively seamless switchover can be achieved from the primary to the backup physical interface.

Virtual interface with active and backup physical interfaces

Systems and methods, consistent with the present invention, provide a high-speed line interface for networking devices. Such an interface may be used in networking devices, such as routers and switches, for receiving data from, and transmitting data to, high-speed links, such as those lines carrying data at rates of 2.5 Gbit/sec, 10 Gbit/sec, and 40 Gbit/sec and more. In a preferred embodiment, the interface deserializes data from an incoming data stream onto a multi-line bus so that the data may be processed at a lower clock speed. Packets are extracted from the data on the multi-line bus and distributed among a plurality of switching/forwarding modules for processing.

A traceless midplane contains substantially no traces, pins, or active components and includes a front portion and a back portion. The front portion includes first connectors. The back portion includes second connectors arranged in a grid pattern. Each of the second connectors includes electrically-conductive conduits that connect the second connector to a corresponding one of the first connectors through the midplane. The second connectors include data connection points, ground connection points, and clock connection points. At least some of the data connection points are separated from each other and from the clock connection points by the ground connection points.
