The invention discloses a data validation, mirroring and error / erasure correction method for the dispersal and protection of one and two-dimensional data at the micro level for computer, communication and storage systems. Each of 256 possible 8-bit data bytes are mirrored with a unique 8-bit ECC byte. The ECC enables 8-bit burst and 4-bit random error detection plus 2-bit random error correction for each encoded data byte. With the data byte and ECC byte configured into a 4 bit×4 bit codeword array and dispersed in either row, column or both dimensions the method can perform dual 4-bit row and column erasure recovery. It is shown that for each codeword there are 12 possible combinations of row and column elements called couplets capable of mirroring the data byte. These byte level micro-mirrors outperform conventional mirroring in that each byte and its ECC mirror can self-detect and self-correct random errors and can recover all dual erasure combinations over four elements. Encoding at the byte quanta level maximizes application flexibility. Also disclosed are fast encode, decode and reconstruction methods via boolean logic, processor instructions and software table look-up with the intent to run at line and application speeds. The new error control method can augment ARQ algorithms and bring resiliency to system fabrics including routers and links previously limited to the recovery of transient errors. Image storage and storage over arrays of static devices can benefit from the two-dimensional capabilities. Applications with critical data integrity requirements can utilize the method for end-to-end protection and validation. An extra ECC byte per codeword extends both the resiliency and dimensionality.

A system and methods for organizing and querying data within a linear grid management system. Data having multiple dimensions is associated with physical locations, where a first dimension is associated with a node and a second dimension is associated with a data storage identifier of a memory storage device. The data may have a third dimension which provides a field for ordering data within the memory storage device. Metadata may be used to map a logical table to data stored in the memory storage device. The data query may be divided into multiple subqueries, wherein each subquery is related directly to one node associated with a data storage identifier related to a memory storage device. A preSQL and postSQL process may be generated to access an external database. A dispatcher may manage data subrequests and a node may generate a unique and efficient parsing process from the received data subrequest.

One implementation of a method reassembles complete client-server conversation streams, applies decoders and / or decompressors, and analyzes the resulting data stream using multi-dimensional content profiling and / or weighted keyword-in-context. The method may detect the extrusion of the data, for example, even if the data has been modified from its original form and / or document type. The decoders may also uncover hidden transport mechanisms such as, for example, e-mail attachments. The method may further detect unauthorized (e.g., rogue) encrypted sessions and stop data transfers deemed malicious. The method allows, for example, for building 2 Gbps (Full-Duplex)-capable extrusion prevention machines.

An improved method of and a system for managing data elements in a multidimensional database (MDB) supported upon a parallel computing platform using modular-arithmetic based address data mapping (i.e. translation) processes on integer-encoded business dimensions. The parallel computing platform has a plurality of processors and one or more storage volumes for physically storing data elements therein at integer-encoded physical addresses in Processor Storage Space (i.e. physical address space in the one or more storage volumes associated with a given processor). The location of each data element in the MDB is specified in MDB Space by integer-encoded business dimensions associated with the data element. A data loading mechanism loads the integer-encoded business dimensions and associated data elements from a data warehouse. The address data mapping mechanism performs a two part address mapping processing. The first step maps the integer-encoded business dimensions associated with each data element to a given processor identifier (which uniquely identifies the processor amongst the plurality of processors of the parallel computing platform). The second step maps the integer-encoded business dimensions associated with each data element into an integer-encoded physical data storage address in Processor Storage Space associated with the processor identified by the processor identifier generated in the first mapping step. The mapping performed in this second step is based upon size of the integer encoded business dimensions. The data management mechanism manages the data elements stored in the storage volumes using the integer-encoded data storage addresses generated during the two-part address data mapping process. The use of modular-arithmetic functions in the two-part address data mapping mechanism ensures that the data elements in the MDB are uniformly distributed among the plurality of processors for balanced loading and processing. The present invention can be used to realize (i) an improved MDB for supporting on-line analytical processing (OLAP) operations, (ii) an improved Internet URL Directory for supporting on-line information searching operations by Web-enabled client machines, as well as (iii) diverse types of MDB-based systems for supporting real-time control of processes in response to complex states of information reflected in the MDB.

A method and apparatus are provided for building a searchable multi-dimensional index tree that indexes a plurality of data objects. In one aspect of the invention, the index tree divides dataspace into three subspaces and indexes the data objects using a single dimension. If too many data objects map to the same point in that dimension, the dimension is switched to a new dimension of the data object and the data object is indexed using the new dimension. A split node having a split value is used to keep track of the indexing. In another aspect of the invention, the index tree divides dataspace into two subspaces, and equal bits are used in the split nodes to track the content of the data objects in the subspaces. If too many data objects sharing the same key within the same dimension map to a single point, then the dimension is switched to a new dimension and the data objects are indexed using the new dimension. Also disclosed is the multi-dimensional index tree itself as well as a router that uses the multi-dimensional index tree of the present invention to provide packet classification functions.

A method and system for conveying an arbitrary mixture of high and low latency traffic streams across a common switch fabric implements a multi-dimensional traffic classification scheme, in which multiple orthogonal traffic classification methods are successively implemented for each traffic stream traversing the system. At least two diverse paths are mapped through the switch fabric, each path being optimized to satisfy respective different latency requirements. A latency classifier is adapted to route each traffic stream to a selected path optimized to satisfy latency requirements most closely matching a respective latency requirement of the traffic stream. A prioritization classifier independently prioritizes traffic streams in each path. A fairness classifier at an egress of each path can be used to enforce fairness between responsive and non-responsive traffic streams in each path. This arrangement enables traffic streams having similar latency requirements to traverse the system through a path optimized for those latency requirements.
