    摘要： Content retrieval techniques are described. In an implementation, a determination is made as to whether a client is permitted to receive content requested by the client. When the client is permitted to receive the content, a communication is formed to be communicated via a wide area network that includes a hash list having a hash of each of a plurality of blocks of the content, each hash being configured to enable the client to locate a corresponding one of the blocks of the content via a local area network.

    摘要： Disclosed is a method for efficiently distributing content by leveraging the use of a peer-to-peer network infrastructure. In a network of peers, a handful peers can receive content from centralized servers. These peers can then flood this content out to more clients who in turn can send the content along to others. Ultimately, a request for content can be fulfilled by locating the closest peer and obtaining the content from that peer. In one embodiment the method can be used to distribute content by creating content distribution groups of one or more client computing devices and redirecting requests for content from the server to the content distribution group. A further contemplated embodiment efficiently streams time sensitive data through the use of a spanning tree architecture of peer-to-peer clients. In yet another embodiment the present invention provides for more efficient use of bandwidth for shared residential broadband connections.

    摘要： A device hosting framework provides hosting for software-implemented logical devices (including peripheral devices bridges) on a computer to expose their services as controlled devices per a peer networking protocol. The device hosting framework encapsulates discovery, description and control protocol operations of the peer networking protocol, which frees the developers of the hosted devices from having to individually implement the peer networking protocol in the hosted devices' software and need implement only the core functionality of the hosted device. The device hosting framework operates as a host supporting device interoperability via the peer networking protocol for multiple hosted devices.

    摘要： Storage and communication de-duplication are described. In one or more implementations, a system comprises one or more modules that are implemented at least partially in hardware, the one or more modules configured to utilize one or more algorithms to calculate hashes of chunks of data, the hashes used to replace the chunks in the data for storage locally in the system as well as to communicate the hashes in response to a request received via a network for the data to avoid communicating at least one of the chunks of the data via the network.

    摘要： Described is a technology in which client content requests to a server over a wide area network (WAN) are responded to with hash information by which the client may locate the content among one or more peer sources coupled to the client via a local area network (LAN). The hash information may be in the form of a segment hash that identifies multiple blocks of content, whereby the server can reference multiple content blocks with a single hash value. Segment boundaries may be adaptive by determining them according to criteria, by dividing streamed content into segments, and/or by processing the content based on the content data (e.g., via RDC or content/application type) to determine split points. Also described is content validation using the hash information, including by generating and walking a Merkle tree to determine higher-level segment hashes in order to match a server-provided hash value.

    摘要翻译： 描述了一种技术，其中客户端内容通过广域网（WAN）向服务器请求的哈希信息被响​​应，客户端可以通过该信息来定位经由局域网耦合到客户端的一个或多个对等端点中的内容（ LAN）。 哈希信息可以是标识多个内容块的段哈希形式，由此服务器可以引用具有单个散列值的多个内容块。 通过根据标准来确定它们，通过将流内容分成段，和/或通过基于内容数据（例如，经由RDC或内容/应用程序类型）处理内容来确定分割点，来分段边界可以是自适应的。 还描述了使用散列信息的内容验证，包括通过生成和行走Merkle树来确定较高级别的段哈希，以便匹配服务器提供的哈希值。

    摘要： Dual stack and/or multi-homed devices networked in a device connectivity architecture include a network location signature field in multicast device or service advertisement or announcement messages for recipients to disambiguate announcements of different addresses for the device. The network location signature is a value representing the device's current network configuration (e.g., set of active addresses), and changes with the network configuration. A recipient control point in the device connectivity architecture can then determine whether announcements of different addresses for the device or service are in addition to a previous announced address, or supercedes any previous announced address.
