Abstract: A computing system is programmed to detect if program content is presented on a channel. A program signature is determined based on set-top box tune data from set-top boxes in a market in which it is known the program content was presented. The program signature can be compared to program signatures from other local markets or from the same market to determine if the same program content was presented. In some embodiments, the program signature represents the number of set-top boxes simultaneously tuned to the channel on which the program content is presented.

Abstract: Embodiments are directed to processing read-only operations without storing the operations persistently, determining a processing order for read-only requests, and to directing read-only requests to nodes best able to handle the requests. In an embodiment, a quorum leader receives various read-only requests. The quorum leader controls process ordering for replicas in the leader's quorum. The quorum leader determines an appropriate order for processing the read-only operations, without clock-based synchronization. The quorum leader sends the read-only request to an appropriate replica in the quorum and executes the read-only request at the appropriate replica without storing the operation persistently.

Abstract: The present invention provides a method of establishing a media transmission link for transmitting a large message mode Converged IP Messaging (CPM) message to a group. The method comprises the following steps: Session Description Protocol (SDP) media parameter negotiation is accomplished through session invite messages and success response messages among a transmitter CPM client, a source participation function entity, a controlling function entity, a destination participation function entity and a receiver CPM client; according to the negotiation result, media transmission links are respectively established between the transmitter CPM client and the source participation function entity, between the source participation function entity and the controlling function entity, between the controlling function entity and the destination participation function entity, and between the destination participation function entity and the receiver CPM client.

Abstract: File reputations are used to identify malicious file sources. Attempts to access files from external sources are monitored. For each monitored attempt to access a file, a reputation of the specific file is determined. Responsive to a determined reputation of a file meeting a threshold, the file is adjudicated to be malicious. Attempts by sources to distribute malicious files are tracked. Responsive to tracked attempts by sources to distribute malicious files, reputations of file sources are determined. Responsive to a determined reputation of a source meeting a threshold, the source is adjudicated to be malicious, and files the source distributes are analyzed to determine whether they comprise malware. Malicious sources are blocked. Malware and malicious sources are analyzed to identify exploits and distribution patterns.

Abstract: The home appliance managing system includes a plurality of central managing devices and a center server. The center server is connected to the plurality of the central managing devices, and stores plural data used at home appliances. When the central managing device stores predetermined data requested by the home appliance, the central managing device sends the predetermined data to the home appliance. When the central managing device does not store the predetermined data, the central managing device requests the predetermined data from the center server. The center server sends the predetermined data to the central managing device in response to the request from the central managing device. The central managing device sends the predetermined data received from the center server to the home appliance and stores the same data.

Abstract: Two parties can establish a cryptographic key using a matrix based key exchange protocol, for secure communications without any prior distribution of secret keys or other secret data, and without revealing said key to any third party who may have access to all of the transmissions between them. The two parties use a shared secret to produce a common matrix M. The common matrix M, is multiplied by a random matrix K on the sending side, and a different random matrix N on the receiving side. The matrix product KM is sent from the sending side to the receiving side, and the matrix product MN is sent from the receiving side to the sending side. Both sides produce the common matrix product KMN, and use it for producing a symmetric key for encrypted communications, after mutually authenticating one another over an insecure network.

Abstract: The present invention is directed towards systems and methods for providing static proximity load balancing via a multi-core intermediary device. An intermediary device providing global server load balancing identifies a size of a location database comprising static proximity information. The intermediary device stores the location database to an external storage of the intermediary device responsive to determining the size of the location database is greater than a predetermined threshold. A first packet processing engine on the device receives a domain name service request for a first location, determines that proximity information for the first location is not stored in a first memory cache, transmits a request to a second packet processing engine for proximity information of the first location, and transmits a request to the external storage for proximity information of the first location responsive to the second packet processing engine not having the proximity information.

Abstract: A method, system and computer program product for accurately predicting capacity requirements for Information Technology (IT) resources in physical, virtual, cloud and hybrid cloud environments. The business demand is translated into IT application demand, which is translated into IT architecture layer demand. Resource groups are created for each IT application, IT architecture layer and resource type combination. The utilization for each IT resource group within the IT architecture layers is computed using the created resource groups, IT application demand and IT architecture layer demand. Under or over-utilized IT resource groups may be identified using the computed utilization for each IT resource group. Upon identifying such IT resources, an optimal resource profile (e.g., number of servers) for each resource group is computed.
