摘要： A primary-backup replication capability is disclosed. A primary process and a backup process participate in a synchronization process configured to synchronize state information of the primary and backup processes. The synchronization process operates in periods of time referred to as epochs. During the current epoch, the primary process computes state update information representing changes to the state information of the primary process since a previous epoch, and also buffers output messages generated during the current epoch in an associated output buffer dedicated for use in the current epoch. The primary process initiates a new epoch independent of receiving, from the backup process, a state update acknowledgement for the previous epoch. The output messages buffered for the current epoch are released from the associated output buffer after the primary process receives a state update acknowledgment for the current epoch and all output buffers of all previous epochs are empty.

摘要： The backup-in-the-middle primary-backup configuration is created by placing a backup-in-the-middle forwarder in the routing path between the primary and the environment. The backup-in-the-middle forwarder intercepts output messages along with required state information sent by the primary to the environment. The backup-in-the-middle forwarder backs up the primary by updating its state information and forwards the output packets to the environment.

摘要： A handwritten test symbol, such as an alphabetic character, a word or a signature, written on a digitizing tablet is normalized by comparison with a model symbol to determine the transformation necessary to best fit the test symbol to the model symbol. Such transformation is then applied to normalize the test symbol. Shape information in the test symbol is preserved during such normalization. In accordance with one aspect of the invention, the model symbol is a line segment. In accordance with another aspect of the invention, the model symbol is an example of the symbol being normalized. Such normalization can be used as a preprocessing step in applications such as character recognition, text recognition or signature verification.

摘要： A method for recognizing a table structure from delineated table region in an electronic document using hierarchical clustering of data strings. The cluster groupings are segregated effectively using the distances from a positional vector associated with words and groups of words rather than a minimum number of blank spaces between words. Once a data tree of the hierarchical clusterings is constructed, the tree is scanned downward from the root to find appropriate column boundaries using a columnization algorithm. Then using successive heuristic algorithms, determine column and row headers and row boundaries.

摘要： Methods and apparatus are provided with improved routing techniques for bifurcated flows. Routing methods and apparatus are provided that obtain a fractional flow from a set of nodes to a given destination having a maximum load, L, on any link between a node in the set and the given destination; and generate a bifurcated flow between the set of nodes and the given destination from the fractional flow such that the maximum load on any link in the bifurcated flow does not exceed 2L, wherein the bifurcated flow allows a flow from a given node to be sent on at most two outgoing links. The fractional flow can be, for example, a fractional single-sink multicommodity flow.

An undirected Cantor network is disclosed where the switch nodes are wavelength selective switches. An undirected Clos cross connect is also disclosed where one or more undirected switches are undirected Cantor networks having at least one wavelength selective switch
