摘要： Context-based routing in multi-hop networks involves using a context-based routing metric. In a described implementation, respective path values are calculated for respective ones of multiple paths using the context-based routing metric. A path is selected from the multiple paths responsive to the calculated path values. Data is transmitted over at least one link of the selected path. In an example embodiment, the context-based routing metric is ascertained responsive to an estimated service interval (ESI) of a bottleneck link of each path of the multiple paths. In another example embodiment, the context-based routing metric is ascertained responsive to an expected resource consumption (ERC) metric. In an example embodiment of path selection, the path is selected using a context-based path pruning (CPP) technique that involves maintaining multiple local contexts at each intermediate node, with each local context representing at least one partial path.

摘要： 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.

摘要： 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.

摘要： 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.
