A bypasser configured to operate within a three tiered synchronization system. The bypasser can include an interceptor and an inference engine. The interceptor can intercept synchronization requests before a synchronization event involving a synchronization server is initiated. The inference engine can determine if the data store and the another data store are to be synchronized and can selectively initiate the synchronization event based on the determination of the inference engine. For example, when the inference engine determines that synchronization is not to occur, the bypasser can convey a notification that no update is needed to the source of an intercepted synchronization request without requiring the synchronization server to process the synchronization request. When the inference engine determines that synchronization is to occur, the bypasser can convey an intercepted synchronization request to the intermediate synchronization server for processing.

A method and system for synchronizing data between a dataset and a data subset, in which filter criteria determine which data records in the dataset are excluded from the data subset. However, the filter is not applied to every record of the dataset during each synchronization. Instead, during a synchronization, the filter is applied to incoming changes received from the data subset and to outgoing changes that are intended to be sent to the data subset. Appropriate actions are taken on these changes to implement the filter parameters. When a filter is changed or newly activated, a method is performed which prepares the synchronization system so that, when the next synchronization is performed, the dataset and the data subset will automatically be synchronized according to the new filter, due to the standard application of the filter parameters during a standard synchronization.

For each item that is synchronized across multiple devices, all the visual representations of such item in the columns are aligned across a single row in the interface. In the preferred embodiment, there is an arrow, or other visual indicator, between the visual representations of such items to indicate that the items are synchronized.

A distributed computing system, having a sufficient number of devices and requiring a sufficiently large number of devices to select any proposal, can maintain synchronization between its constituent devices and respond to client requests with as few as two message delays. A leader can synchronize the devices of the system and establish a safe proposal number for all current and future steps of the system. Devices can then receive client requests directly, treating the request as a proposal having the proposal number determined previously by the leader, and voting for the proposal. If the client receives an indication from a least a quorum of devices, where a quorum can be the minimum number of devices that can be operational at a given time, the client can know that the request was selected. If two or more clients attempt to request different functions at approximately the same time, the system may not select either request, in which case a leader can be requested to determine if any requests may have been selected, and to reestablish a safe proposal number. Systems with fewer devices can also implement the message-delay-reducing algorithm if they can also revert to the standard Paxos algorithm if an insufficient number of devices are operational. Such algorithms can be used to provide an efficient method for determining whether to commit or abort a client transaction.

Synchronizing audio and video streams in packet-based networks requires synchronization of packet timestamps. The present invention provides such synchronization without resort to a network time standard. In one embodiment of the present invention, pairs of timestamp synchronized signals, such as audio and video signals, not having a common timestamp clock are mixed. One of the signals, for example, the audio signals, is mixed first while preserving the original audio timestamps. The preserved timestamp information is then used to synchronize the timestamps of the unmixed signals, in this example the video signals, to provide synchronization of all signals. In another embodiment, the present invention uses packets containing calibration of timestamps to reduce jitter. The present invention also includes specifications for a packet for transmitting timestamp information.

A distributed synchronization system for use in each node of a distributed asynchronous telecommunications network system that continually monitors and controls the flow of data through an implementing node to prevent dataflow errors due to phase and frequency differences in source and destination nodal clocks, and to control inter-nodal network latency so as to support the transmission of synchronous data. A synchronization data FIFO buffers predetermined fields or portions of fields of a unique frame packet received from a source node before retransmission to a destination node on the network. The frame packet includes a frame synchronization field indicating the beginning of a new frame packet; a payload field containing valid data; and a dead zone field providing bandwidth during which the present invention performs synchronization functions. A frame synchronization subsystem, implemented in a designated master node, guarantees that a frame is released at the beginning of an independently-determined frame regardless of network latency. A word resynchronization subsystem manages the flow of data through the data FIFO of each non-master node, receiving and storing data at the source node's clock rate and transmitting the data according to its own clock, thereby guaranteeing the efficient receipt and transmission of data between asynchronously-communicating nodes.
