    • Described is a technology, such as implemented as social networking groupware application designed for mobile device users, that provides a data mashup service for various data types, including location dependent and mobility-aware data such as GPS location and surrounding maps. A mobile user may track the location and maps of roaming friends at runtime. To this end, a client device joins a squad of client devices that are each capable of communicating with one another over a wireless local area network (WLAN) connection. When in a squad, the client can obtain data for use as mashup information from other client devices in the squad over the WLAN connection (inter-squad). This may include intra-squad data that was obtained from a service based on information that the service received from another squad, e.g., over a WWAN connection.
    • 描述了一种技术,例如被实现为针对移动设备用户设计的社交网络组件应用,为各种数据类型提供数据混搭服务,包括位置依赖和移动感知数据,例如GPS位置和周围地图。 移动用户可以在运行时跟踪漫游朋友的位置和地图。 为此,客户端设备加入能够通过无线局域网(WLAN)连接彼此进行通信的客户端设备。 在一个小队中,客户端可以通过无线局域网连接(小队间)获取数据作为混合来自其他客户端设备的混搭信息。 这可以包括从服务中获得的小队内数据,该数据是基于服务从另一小队接收的信息,例如通过WWAN连接。

    • Efficient reconciliation of different versions of a target file or dataset can be facilitated using a hash hierarchy of a master version of the dataset. Each level of the hash hierarchy has hashes of blocks of the master version that may be sub-blocks of the hashes in the level above. The top level of the hash hierarchy, having the hashes of the largest blocks of the master, may be transmitted on a first communication channel, possibly a one-way or broadcast communication channel. Streams of encodings of each lower level of the hash hierarchy may be transmitted on respective communication channels. The encodings for a level of the hierarchy may be combinations, such as random linear combinations, of the hashes of that level. A receiver with a target dataset can receive the top level hashes from the first channel and use them to determine which lower hashes are needed to identify parts of the master missing from the target. The encodings can be used to help obtain needed lower level hashes that can be used to more finely identify missing parts. Different receivers may not have to wait for a particular piece of information about the master. Rather, any received information (e.g. encoding) about the master will most likely allow any receiver to advance its understanding of the master dataset. Receivers will usually not have to wait for delivery of a particular hash in the hierarchy.
    • 可以使用数据集的主版本的散列层次结构来促进目标文件或数据集的不同版本的高效协调。 散列层次结构的每个级别都具有可以是上述级别中的散列子块的主版本块的散列。 可以在第一通信信道,可能是单向或广播通信信道上发送具有主机的最大块的散列的散列层级的顶层。 可以在各个通信信道上发送散列层级的每个较低级别的编码流。 层级的级别的编码可以是该级别的散列的组合,诸如随机线性组合。 具有目标数据集的接收器可以从第一个通道接收顶级散列,并使用它们来确定需要哪些较低的散列来识别目标中丢失的主要部分。 编码可用于帮助获得所需的较低级别的哈希值,可用于更精确地识别缺失的部分。 不同的接收机可能不必等待关于主机的特定信息。 相反,关于主机的任何接收到的信息(例如编码)将很可能允许任何接收机提高对主数据集的理解。 接收者通常不必等待传递层次结构中的特定散列。

    • A serverless name resolution protocol ensures convergence despite the size of the network, without requiring an ever-increasing cache and with a reasonable numbers of hops. This convergence is ensured through a multi-level cache and a proactive cache initialization strategy. The multi-level cache is built based on a circular number space. Each level contains information from different levels of slivers of the circular space. A mechanism is included to add a level to the multi-level cache when the node determines that the last level is full. A peer-to-peer name resolution protocol (PNRP) includes a mechanism to allow resolution of names which are mapped onto the circular number space through a hash function. Further, the PNRP may also operate with the domain name system by providing each node with an identification consisting of a domain name service (DNS) component and a unique number.
    • 无需服务器的名称解析协议确保收敛,尽管网络的大小,而不需要越来越多的缓存和合理的跳数。 这种融合通过多级缓存和主动缓存初始化策略来确保。 多级缓存基于循环数字空间构建。 每个级别都包含来自不同级别的圆形空间的信息。 当节点确定最后一个级别已满时,包括一个机制来向多级缓存添加级别。 对等名称解析协议(PNRP)包括允许通过散列函数映射到循环号码空间的名称的解析机制。 此外,PNRP还可以通过为每个节点提供由域名服务(DNS)组件和唯一号码组成的标识来与域名系统一起操作。

    • A system and method for a media processor separates the functions of topology creation and maintenance from the functions of processing data through a topology. The system includes a control layer including a topology generating element to generate a topology describing a set of input multimedia streams, one or more sources for the input multimedia streams, a sequence of operations to perform on the multimedia data, and a set of output multimedia streams, and a media processor to govern the passing of the multimedia data as described in the topology and govern the performance of the sequence of multimedia operations on the multimedia data to create the set of output multimedia streams. The core layer includes the input media streams, the sources for the input multimedia streams, one or more transforms to operate on the multimedia data, stream sinks, and media sinks to provide the set of output multimedia streams.
