Abstract: Some embodiments are associated with a data center cloud computing environment executing a plurality of virtual machines. A virtual machine data store may contain information about the plurality of virtual machines associated with the cloud computing environment. A virtual machine test platform may access the information in the virtual machine data store and periodically initiate a network test for each of the plurality of virtual machines based on the information in the virtual machine data store. The virtual machine test platform may then receive network test result signals from the virtual machines in response to the executed network tests and apply, for each virtual machine, a digital signal processing noise filter to successive network test result signals from that virtual machine. An output of the digital signal processing noise filters may then be transmitted from the virtual machine test platform.

Abstract: An invention is disclosed for updating a networked, single-threaded application's data model without blocking the application's entire user interface. In embodiments of the invention, a client executes a networked application with a single-threaded user interface that communicates with a server to refresh its data model. The client sends a message to the server that requests a refresh of the data model. Before the data model has been refreshed, the client receives local user input to perform an action on the data model. The client sends a message to the server to cancel the refresh. When the client receives an acknowledgement from the server that the refresh has been cancelled, the client performs the action. After performing the action, the client sends a second message to the server that requests a refresh of the data model, and then refreshes the data model upon receiving the refreshed data model from the server.

Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.
