Abstract:
In one embodiment, a method includes one or more computing devices accessing a notification to be sent to a user, where the notification has a context. The method also includes one or more computing devices sending a request to a history service for historical notification data associated with the user with respect to the context of the notification and a ranking of the notification where the ranking indicates a probability of the user interacting with the notification. The method also includes one or more computing devices receiving the historical notification data and the ranking from the history service. Moreover, the method also includes one or more computing devices determining a notification policy to apply to the notification based at least in part on the context of the notification, the historical notification data, and the ranking. Furthermore, the method also includes one or more computing devices applying the notification policy to the notification to be sent to the user.
Abstract:
At least one of a set of topics published by one or more vehicle-located mobile gateways is subscribed to. A set of publication topics is created based on the first set of topics, the publication topics made available to a client. A subscription request is received from the client corresponding to a selected topic of the set of publication topics. First sequential data is received from the one or more mobile gateways in response to the subscription to the at least one of the set of topics of the one or more mobile gateways. Second sequential data is sent to the client responsive to the subscription request, the second sequential data being based on the first sequential data.
Abstract:
A technology for device to device (D2D) communication scheduling is disclosed. A D2D device can be synchronized with a base station of a cellular system. A sub-frame symbol boundary can be identified in the cellular system for the D2D communication. A resource for a D2D communication can be allocated from the D2D device to another D2D device within the sub-frame boundary of the cellular system. The D2D device can be switched to perform a D2D communication with another D2D device in proximity with the D2D device, wherein the other D2D device is substantially synchronized with the base station of the cellular system. The D2D device can communicate with the other D2D device within at least one symbol boundary time within the selected subframe.
Abstract:
The present invention relates to a method of, and device for, arranging a P2P network comprising a streaming source and network peers arranged at distribution levels in the P2P network, in which P2P network the streaming source is arranged to divide data content to be streamed into a plurality of content sub-streams together forming the data content and to distribute the plurality of content sub-streams to the network peers. The method comprises instructing a network peer requesting to download data content to download a single content sub-stream from a respective one of selected network peers being arranged at a distribution level closer to the streaming source than the requesting network peer until a number of content sub-streams have been downloaded by the requesting network peer from which the requested data content can be formed. The present invention further relates to a method of requesting data content in a P2P network and a peer device.
Abstract:
In one embodiment, a method for collecting updates for a plurality of objects over a cloud data network includes: determining a set of remote devices known to have updates for a selected object, wherein each of said remote devices maintains a set of locally updated objects that includes the selected object; and downloading the updates for the selected object from said set of remote devices. Where said downloading the updates for the selected object results in a name conflict, the method further includes resolving said name conflict, wherein said resolving includes selecting said selected object as a target and said existing object as an alias having a pointer relationship to the target; and merging all meta-data of the alias object into the target.
Abstract:
According to a peer-to-peer protocol, a peer-to-peer network includes multiple clubs and multiple peers that receive content distributed by a source of the network. Each of the plurality of peers is part of at least two of the clubs. As content is generated, the source divides the content into multiple data blocks and assigns each data block to a club. Each data block is transmitted to peers that belong to the club assigned to the data block. When a peer in a club receives a data block assigned to that club, the peer distributes the data block to other peers in the club. Additionally, the peer transmits the data block to peers in other clubs. Also, the peer receives data blocks assigned to other clubs from peers that are not members of the club.
Abstract:
The present invention relates to methods and arrangements for locating services in a structured peer-to-peer distributed hash table, DHT, based, overlay communication network (310). The invention comprises two inter-related methods and nodes. The first method is used by a service node (321) to ''advertise' to the overlay network (310) that it is providing a particular service (Sl). This is done by distributing instances (351,352,353) of a service object (01) that are stored in different nodes (331,332,333) in the overlay network (310) and where the instances (351,352,353) comprise an address to the service node (321). The other method is to locate at least one of these instances (351,352,353) with a predetermined probability and with a predetermined number of location request messages (390) from a user node (311) wishing to use the particular service (Sl).
Abstract:
The present invention comprises a content delivery system (510) for delivering content to clients (628, 660). The content delivery system (510) comprises at least one mobile object (512) adapted to be executed on the content delivery system (510) and on other content delivery systems (520) or multimedia devices (620) adapted for mobile objects. Each mobile object (512) comprises a media file (513) and is further adapted to determine the capabilities of the other content delivery systems (520) or multimedia devices (620) and to monitor data related to the clients' (628, 660) access of the media file (513). The content delivery system (510) also comprises a transcoder unit (519) for transcoding the media file (513) to another media file (523) prior sending it to the other content delivery system (520) or multimedia device (620). The invention solves problems that can arise when sending large media files to content delivery systems (520) or multimedia devices (620) having limited capabilities.
