  • Patent number: 10764748
    Abstract: Disclosed is a method for user identity authentication for a peer device joining a peer-to-peer overlay network. In the method, a credential server of the overlay network receives a registered user identity from a joining peer device. The credential server verifies the registered user identity with an identity provider. Upon receiving, at the credential server, successful verification of the registered user identity from the identity provider, the credential server issues to the joining peer device a signed certificate for use by an authenticated peer device in the overlay network to authenticate the registered user identity of the joining peer device, wherein the signed certificate is signed by a private key of the credential server.

  • Publication number: 20170207979
    Abstract: Methods and apparatus for enhanced overlay state maintenance in a peer-to-peer overlay network. A first method includes inferring that a first node is leaving the overlay network, and transmitting a decrement message to decrement a size counter value. A second method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a segment length associated with each node of the set of nodes, and determining a size of the overlay network by dividing the total number of nodes in the set of nodes by the sum of the segment lengths. A third method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a size estimate associated with the first node and with each node of the set of nodes, and determining a size of the overlay network by averaging the size estimates.

  • Patent number: 9146909
    Abstract: Methods and devices include a server and at least two web browsers operable on at least two different computing devices. Each browser reports results of processing and rendering of webpages to the server. The server aggregates the data. The server generates metadata from the aggregated browsers. The server transmits the generated metadata to at least one computing device. The computing device renders a webpage using at least a portion of the provided metadata. The metadata may identify portions of JavaScript that can be processed in parallel. The metadata may identify a library portion that does not have to be loaded. The metadata may identify a portion of the webpage that may be rendered first before a second portion of the webpage. Returning metadata to the computing device can assist the computing device in parsing, analyzing or executing the request for the webpage.

  • Patent number: 8874781
    Abstract: Systems and methods for delivering social network updates from popular entities to receiver devices via broadcast or multicast networks obtain updates from highly popular entities. Updates may be assembled by a server crawling social network sites. To enable selective reception, the obtained updates may be broadcast/multicast according to a schedule that is communicated to receiver devices in advance, such as a catalog file. Receiver devices receive the catalog file and use the included information to selectively receive updates that are relevant to a user of the receiver device. Updates received from broadcasts or multicasts are cached in memory of the receiver device. When a user requests to access a particular social network entity on the receiver device, that request may be satisfied by accessing social network updates cached on the receiver device. Broadcasting and/or multicasting highly popular social network updates may relieve burdens on unicast networks.

  • Patent number: 8782532
    Abstract: A mobile computing device adapted to request to receive a plurality of objects comprising a website in a new order, the new order being different than an original order, wherein, at least a portion of the original order comprises an order provided from a base level website object. The new order for requesting to receive the plurality of objects is based on at least one of a plurality of metrics. The metrics comprise a depth of each of the plurality of objects, one or more children of the plurality of objects, an object type for each of the plurality of objects, whether a connection has been established with a domain servicing each of the plurality of objects, and when the connection was last established to the domain servicing each of the plurality of objects.

  • Publication number: 20130102334
    Abstract: Disclosed are systems, methods and techniques for classifying portions of an area depicted in a digitally encoded map. For example, features in a digitally encoded map may be extracted to identify a component area at least partially bounded by a perimeter formed by structures. One or more egress segments in the perimeter may be identified and characterized. The component area may then be classified based, at least in part, on a proportionality of a length of the egress segment to a size of at least one dimension of the component area.
