Patent number: 8627403Abstract: Provided are, among other things, systems, methods and techniques for determining applicability of a policy defined by reference to a source document. A first sketch that was generated based on content of the source document is obtained, and a matching criterion is defined based on the first sketch. Also obtained is a second sketch that was generated based on content of a potential target document. A determination is made as to whether the policy applies to the potential target document based on whether the second sketch satisfies the matching criterion and, if the policy applies, a notification regarding applicability of the policy automatically is provided and/or an action automatically is blocked so as to prevent a violation of the policy.Type: GrantFiled: July 31, 2007Date of Patent: January 7, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Evan R.

Patent number: 7634575Abstract: A method for clustering data streams. Specifically, one embodiment of the present invention discloses a method for clustering data streams for use in a virtual environment. The embodiment of the method begins by determining a cluster of receiving nodes in the virtual environment. Each of the cluster of receiving nodes have associated values for at least one clustering parameter that as a set satisfies a test. Then, the embodiment continues by generating a common data stream based on the clustering parameter. Thereafter, the embodiment sends the common data stream from a sending node to the cluster of receiving nodes.Type: GrantFiled: October 9, 2003Date of Patent: December 15, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventors: W.
