    摘要: A method includes sending signals from two nodes to a landmark, identifying common milestones along the routes, and determining distance information from the nodes to at least one of the common milestones. A system includes a program configured to send signals from two nodes to a landmark, identify common milestones along the routes, and provide distance information from each node to at least one of the common milestones, and a program configured to receive the distance information and provide a latency estimate based on the distance information.

    摘要: A switch (100) connected to a network is configured to have one or more components that can be placed in a deep sleep mode. The switch (100) includes a management circuit (150) that is configured to wake up the components in deep sleep mode. The management circuit (150) includes a port (151) that receives packets and a wake-up circuit (152) that determines whether a packet received via the port (151) is a magic packet including a unique ID for the port (151) or the switch (100). If the packet is the magic packet including the unique ID for the port (151) or the switch (100), the wake-up circuit (151) is configured to send a wake-up signal to components in the switch (100) to wake up from the deep sleep mode.

    摘要: The present disclosure allows for the downloading of large digital media files in a progressive manner by allowing for a transfer of such digital media to occur over various sessions. A file server is described that receives a request to transmit a file whereupon the file server locates such requested file in its memory. For verification purposes a unique identifier is computed for the requested file such as an MD5 checksum of the digital file. Thereafter an encryption key, K1, is chosen. Using a second key, K2, the first key and the unique identifier are encrypted, and the requested file is encrypted using the first key. Both these encrypted values are then transmitted. Subsequently, for example, after payment is received, an unencrypted form of the first key is also transmitted. The first key can then be used to decrypt the requested file to unlock full functionality of the requested file.

    摘要: Local rules for managing flows devolved from a central controller are received at a switch. The central controller determines a global set of rules for managing flows. The switch receives a packet from a flow from a network and determines whether a metric for the flow satisfies a dynamic condition to trigger a metric report to the central controller. In response to a determination that the metric for the flow at the switch satisfies the dynamic condition to trigger a metric report to the central controller, the switch sends a metric report to the central controller, and the switch then receives an instruction to manage the flow from the central controller. In response to a determination that the metric for the flow at the switch does not satisfy the dynamic condition to trigger the metric report to the central controller, the switch manages the flow using the local rules for managing flows.

    摘要: A network includes a plurality of nodes. A set of candidate nodes from the plurality of nodes is selected based on location information for the candidate nodes and a first node also in the network. A clustering algorithm is applied to the location information for the candidate nodes and the first node, and a subset of the set of candidate nodes closest to the first node is identified based on the results of applying the clustering algorithm.
