A fault-tolerant replication system includes a first machine running a first hypervisor. A second machine is failure-independent of the first machine. The second machine runs a second hypervisor. A first plurality of virtual machines runs on the first hypervisor. A second plurality of virtual machines runs on the second hypervisor. Each of the virtual machines of the first and second plurality of virtual machines constitutes either a virtual machine replica server of a fault-tolerant replicated state machine or a backup corresponding to a virtual machine replica server of the fault-tolerant replicated state machine. Every backup is embodied on a different machine, of the first and second machines, from its corresponding virtual machine replica server.

Fault-tolerant replication architecture

A system for automatically monitoring and controlling an infrastructure or process includes a plurality of remote clients installed along various portions of an industrial infrastructure or an infrastructure performing a process. Each of the remote clients collects data. A plurality of server replicas is in communication with the plurality of remote clients. The server replicas receive the collected data from the remote clients and process the received data. The plurality of remote clients and the plurality of server replicas communicate across an electronic network. The plurality of server replicas includes a state machine replication system that is tolerant of a failure of one or more of the server replicas.

Byzantine fault-tolerant SCADA system

A network of replicated servers providing a service includes a plurality of server replicas. A leader is elected from among the plurality of server replicas for coordinating ordering of operations among the plurality of server replicas. A view change protocol is executed by the plurality of server replicas after the election of the leader. Each iteration of the view change protocol corresponds to a unique view number. The server replicas are directed by the view change protocol to cooperate to order operations by exchange of information associated with particular view numbers. The information is prioritized in accordance with the view numbers. The non-leaders monitor the response time of the leader and elect a new leader when it is determined that the monitored length of time is greater than a threshold value that is dependent upon current network conditions.

Replicated state machine utilizing view change protocol resilient to performance attacks

Some embodiments provide a touch-sensitive device to receive a bias and to generate touch location information based on the bias, an element to secure a printed medium in contact with the touch sensitive device, the printed medium to depict a plurality of telephone interface controls, a memory to store a telephone interface layout associating one or more of the telephone interface controls with a respective touch location and a respective action, and a processor to receive touch location information from the touch-sensitive device, to determine a telephone interface control based on the touch location information and on the telephone interface layout, to determine an action based on the telephone interface control and on the telephone interface layout, and to perform the determined action.

Systems for development and/or use of telephone user interface

A telecommunications system including a plurality of switches defining an Ethernet ring; a plurality of virtual local area networks defined on the Ethernet ring, defining a number of virtual local area networks (VLANs) equal in number to the number of links; and a ring recovery system configured to recover from a link failure by rerouting traffic to a destination on the Ethernet ring via a VLAN not including a failed link.

Methods and apparatus for decentralized rapid recovery for Ethernet rings

According to some embodiments, a method and a system are provided to receive a first video signal at a first client and to receive a second video signal at a second client. The first video signal comprises an image of a first person and the second video signal comprises an image of a second person. The received first video signal and an image of a conference room are combined at the first client to create a first modified video signal comprising the image of the first person in the conference room. The received second video signal and the image of the conference room are combined at the second client to create a second modified video signal comprising the image of the second person in the conference room.

In one aspect of the present invention, a system for discovering potential devices on a peer-to peer (P2P) network is provided. The system includes a seeker device and a plurality of potential devices operatively connected to the P2P network. Each of the plurality of potential devices is associated with one or more identity files. Each of the identity files comprising a plurality of searchable elements. One or more of the plurality of potential end-user devices post their one or more identity files on the P2P network. The seeker device searches the P2P network to discover one or more of the plurality of potential devices based on the one or more identity files of the plurality of the potential devices. The seeker device initiates a collaboration session with the one or more potential devices. The collaboration session may be independent of the P2P network.

Meta-search web service-based architecture for peer-to-peer collaboration and voice-over-IP

A general interaction interface system comprises a composite device access point connected to a client device, wherein the composite device is adapted to receive a request from the client device. The system further comprises a composite device gateway connected to the composite device access point, wherein the composite device gateway determines content and delivery parameters based on interaction primitives of the composite device access point, and a composite device resource, selected by the composite device gateway, for servicing the request of the client device.

A method for linearizing framesets for audibly rendering structured document frames, in accordance with the present invention, includes accessing a document including a frameset. Frames of the frameset are ranked in accordance with positional locations of each frame in the frameset such that each frame is uniquely ordered in the frameset. A linearized document is generated for the frameset for rendering by an audio browser.

Linearization of framesets for audibly rendering frames

A down-sampling system for digital waveforms performs real-time, &ldquo;on the fly&rdquo;, conversions and results in data of acceptable quality for many applications including applications dealing primarily with speech data. The down-sampler comprises a weight matrix calculator and a loop in which the system takes the input data from the producer's data stream, and at one chunk at a time, the system generates the output data. The loop comprises an input receiver, a chunk receiver, an output chunk generator, a chunk decider for deciding whether there is another chunk in the input, and an input decider for deciding whether there is more input.
