Abstract: A server system identifies structured data for protection and creates an index of the structured data, the index comprising a set of Bloom filters. The server system distributes the index to an endpoint device to enable the endpoint device to monitor for structured data occurring in free text data associated with the endpoint device. The endpoint device may load, from the index file, a set of Bloom filters into memory and identify free text data for monitoring. The endpoint device may then determine whether the free text data contains at least a portion of the structured data using the set of Bloom filters.

Additionally, a first processing element in the operator graph includes a barrier operator that joins the output of one or more upstream operators included on one or more of the plurality of processing elements. Embodiments initiate one or more timeout conditions at the barrier operator. Embodiments also determine, at the first processing element, that one or more timeout conditions have been satisfied before data has been received from each of the one or more upstream operators.

Abstract: Embodiments relate to combinatorial optimization of multiple resources across a set of cloud-based networks. In aspects, a set of usage histories can store patterns for users in a host cloud-based network recording the consumption of processor, memory, storage, operating system, application, or other resources subscribed to by the user. The user can be a corporation or other collective user. A deployment engine can identify similar target resources available in a set of target clouds. The engine can receive selection criteria for selecting target clouds for a migration of the user's deployment. In the combinatorial selection, each target cloud can independently supply one or more target resources. The engine can thus identify a series of combinations of target resources and target clouds supplying those resources to discover combinations of target clouds and target resources that can satisfy or optimize the selection criteria, such as cost or others.

Abstract: A method, a remote access server and a system for configuring a QoS parameter are provided. In the method, the RAS and the system, when performing QoS configuration, a first network sends data traffic description information of a data traffic to be transmitted to a second network, so that the second network may perform QoS configuration of the second network according to the data traffic description information; and after completing local configuration, an RAS of the first network directly returns a configuration completion response to a QoS management device of the first network without waiting for a configuration completion message returned by the second network, so that the QoS management device of the first network continues performing the QoS configuration of the first network, thereby achieving parallel QoS configuration of the first network and the second network, reducing the delay of the QoS configuration.

Abstract: The present invention relates to a method and device for arranging peers in a P2P network. To this end, a request is received from a peer entering the network to receive data content. Thereafter, a latency is determined with which the entering peer is to receive the data content with respect to a real-time playback point of the data content distributed by the streaming source. After the latency has been determined, the entering peer is provided with a plurality of randomly selected peers from which the requested data content can be downloaded with an expected probability depending on the determined latency. Thus, the entering peer is enabled to download, with the expected probability, the requested data content from a selected one of the randomly selected peers having a lower latency than that determined for the entering peer.

Abstract: A computing device receives instructions, from a user, to send an email message and determines if the email message includes an attachment. When the email message does not include an attachment, the computing device conducts a scan of text of the email message for implications that an attachment should be included. When the email message includes an attachment, the computing device conducts a scan of the email text for implications of a particular type of attachment. The computing device provides, to the user, a notification when there is a positive result from the scan of the email text for implications that an attachment should be included or from the scan of the email text for implications of a particular type of attachment.

Abstract: Automated file distribution is described. A member of a peer-to-peer network receives from a file server, a file to be distributed. The file is then distributed via the peer-to-peer network to other members of the peer-to-peer network. Members of the peer-to-peer network can choose whether or not to receive a file from another member based on a trust level or reputation associated with the member. The trust level may be based, at least in part, on a number of degrees of separation between the members. Furthermore the file is verified, for example, by validating a digital signature associated with the file.

Abstract: A configuration as discussed herein includes a content management system. The content management system can reside in a central location or be distributed amongst multiple different locations in a network environment. In general, the content management system keeps track of configuration information for the retrieval of content. For example, the content management system identifies a presence of one or more content delivery sources in the network environment. The content management system utilizes the contact information to communicate with content delivery sources for discovery of configuration information. The configuration information can indicate: i) a respective address of the content delivery source, ii) a type of content outputted by the respective address, iii) a format of the content such as streaming data outputted by the respective address. The configuration information can be used to identify an address in which to retrieve requested content according to a desired format.
