摘要： A method for transmitting records of changes to data from a production location to a storage location. The method stores in a log, records of changes to data stored at a production location. Those records are transmitted and a transmitted records checkpoint is generated that is transmitted at the end of the transmitted records. A records checkpoint conformation is received and the plurality of transmitted records are purged from the log.

摘要： An interprocess communications platform enables individual processes to request and exchange data in a shared memory space, mediated by a communications engine. Processes, such as applications or other software running under an operating system or in a network, register to blocks of a shared memory space via an administrative memory space which tracks pointers, handles and other indicators of memory areas populated by individual processes. When one process requests access to a variable, pointer or other data generated by another process, the request is mediated by the communications engine. The communications engine may locate the target data belonging to the other process in the shared memory space, via a lookup of relative addressing in a separate administrative memory space. The communications engine, memory management objects and other resources may then lock the portion of the shared memory space allocated to the target process to permit the requesting process to access the data. Data may therefore be exchange between given processes while maintaining data integrity, and also may be cached in the shared memory space or elsewhere by the communications engine to further increase efficiency. Available memory in the shared memory space may be managed using the so-called buddy system or other heap or other management techniques. No named pipes or similar mechanisms under an operating system need be invoked.

摘要： A software components and methods are provided for implementation of a client side HTTP stack, which provide high performance and scalability. Multithreading and completion ports are employed in the client side HTTP layer in association with sockets and a thread pool, thereby providing support for business-to-business and other more recent client side applications which create numerous requests. The invention further comprises a dedicated scheduler thread adapted to activate an object scheduled to begin sending requests at a specific time, as well as a dedicated DNS thread used for resolving symbolic domain names into IP addresses. In addition, the client side HTTP stack implementation comprises a dedicated timeout thread with a list of active sockets and timers associated with each socket to allow finer grain control over socket timeout periods.

摘要： A system and method for simulating network connection characteristics by alteration of a network packet. In general, the method of the invention includes providing a driver that is capable of accessing all outgoing and incoming network packets and altering a network packet to simulate a connection characteristic of the network. In particular, the method of the invention includes receiving a network packet, assigning a new, simulated network address to the network packet and performing modification of the network packet to simulate certain network connection characteristics (including, for example, transmission delay, limited bandwidth, packet dropping, packet fragmentation, packet duplication and packet reordering). The system of the invention includes a modification module for altering certain characteristics of a packet. The modification module is capable of mapping a new, simulated network address to a network packet, modifying a propagation characteristic of the network connection, and altering an additional packet characteristic.

摘要： The invention deploys a message-based data transport platform, in which a communication engine controls the delivery of server or other backup data or other large quantity data to a remote site based on message objects as fundamental units. Data sessions from one or more servers or other data sources may be buffered over established pipes for delivery to a remote data host which likewise contains messaging control. Relatively large message units may wait for communication over the channel in a queue, and be released when prior messaging is complete. Completion port or other polling or other mechanisms may indicate that connections have become open for use. In embodiments the message objects may be signed, or encrypted to safeguard against alteration or unauthorized viewing. The communication engine may rely upon TCP or other underlying transport mechanisms to effect lower level transmission.
