    Abstract: In one embodiment, a method comprises detecting, by an access network computing node, a network service provided by a service provider for one or more identified endpoint devices via a wide area network connection, the access network computing node within an access network providing connections for the one or more identified endpoint devices to access the network service via the wide area network connection; detecting an unavailability of the network service via the wide area network connection; and supplying, by the access network computing node, at least a substitute of the network service for the one or more identified endpoint devices in response to the detected unavailability of the network service via the wide area network connection.

    Abstract: A precaching system identifies an object, such as a media file, that a user accesses and then analyzes a social graph of the user to identify social graph contacts that may be interested in the object. Based on the content of the object—and the interests and connections of contacts in the social graph—the precaching system determines whether a particular contact in the user's social graph is likely also to access the object. For example, the precaching system may determine a hit score corresponding to the object and a likelihood that the particular contact in the social graph will access the object. If the precaching system determines that the likelihood that the particular contact will access the object meets or exceeds a threshold probability level for precaching the object, the precaching system precaches the object near the contact in anticipation that the contact will access the object.

    Abstract translation: 预制系统识别用户访问的对象，例如媒体文件，然后分析用户的社交图，以识别可能对该对象感兴趣的社交图表联系人。 基于对象的内容以及社交图中的联系人的兴趣和联系，预制系统确定用户社交图中的特定联系人是否也可能访问该对象。 例如，预制系统可以确定与对象相对应的命中得分以及社交图中的特定联系人访问对象的可能性。 如果预制系统确定特定联系人将访问对象的可能性满足或超过用于预对象的阈值概率级别，则预先预处理系统预期接触点附近的对象预期该联系人将访问该对象。

    Abstract: In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.

    Abstract: A device includes a multistage filter and an elephant trap. The multistage filter has hash functions and an array. The multistage filter is operable to receive a packet associated with a candidate heavy network user and send the packet to the hash functions. The hash functions generate hash function output values corresponding to indices in the array. The elephant trap is connected to the multistage filter. The elephant trap includes a buffer and probabilistic sampling logic. The probabilistic sampling logic is operable to attempt to add information associated with the packet to the buffer a particular percentage of the time based in part on the result of the multistage filter lookup. The buffer is operable to hold information associated with the packet, counter information, and timestamp information.
