Mechanism for enabling a network address to be shared by multiple labeled containers
Granted: January 20, 2015
Patent Number:
8938554
A mechanism is disclosed for enabling a network address to be shared by multiple containers. By allowing multiple containers to share a network address, a limit on network addresses does not limit the number of containers that can be implemented. Despite the fact that the network address is shared by multiple containers, the uniqueness and isolation of each container is still maintained. In one implementation, this is achieved by associating a unique label with each container. With this…

Redistributing computation work between data producers and data consumers
Granted: January 13, 2015
Patent Number:
8935227
In a consumer-producer distributed model of computing, consumers request data from producers and perform computing work on the data received from the producers, thereby transforming the data. At least some of the computing work performed by a consumer on data provided by the producer is commutable between the consumer and producer, that is, either the producer as well as the consumer can perform the computing work on the data. A producer redistributes commutable based on the work load of…
Referentially-complete data subsetting using relational databases
Granted: January 13, 2015
Patent Number:
8935234
A method, system, and computer program product for relational database management. The method constructs a referentially-complete target subset database from a source database by first estimating the expected size of the target subset database based on application of one or more subsetting rules. If the estimated size needs reduction, the user can modify the subsetting rules, and then modules are invoked to receive the modified subset rules. The method continues by generating a…
Visualization of concepts within a collection of information
