Autonomous mapping of protected data streams to Fibre channel frames

InactiveUS20080307122A1Minimize involvementPerform other taskTransmissionElectric digital data processingData streamFibre Channel
A hardware-based offload engine is disclosed for mapping protected data into frames. For a write operation, the HBA determines host addresses and the size of data to be read from those addresses. The HBA also determines the frame size and protection scheme for data to be written. A frame transmit engine reads each host descriptor in the host data descriptor list to determine the location and byte count of the data to be read. A DMA engine reads the protection information / scratch area to determine the exact data size used to fill each frame and the protection scheme, and retrieves one or more free frame buffers. Check bytes are inserted alongside the data and stored in free frame buffers. After each frame is filled, the frame transmit engine also generates and stores header information for that frame, and then combines header, data and check bytes for transmission over the network.

Systems and methods for website monitoring and load testing via simulation

Described herein are systems and methods for website or web based application monitoring and load testing. A server is configured to execute monitoring or load testing agents on various agent devices that are placed in various locations across a network. The agents receive a playback script from the server and execute the script to simulate a user session that is part of a website monitoring or load testing project. Execution of the playback script may cause the agent to send commands to a generic browser application that in turn carries out those commands. Alternatively, or in combination, execution of the script may cause the agent to simulate operating system commands such as mouse, keyboard, and voice commands. The results of the script execution by the agent are stored and sent back to the server for potential real time alerting notification and compilation into a related report.

Individual test steps of BDD test scenarios are first matched and then assigned to existing test step definitions from a BDD framework. If a one-to- one matching is not possible, natural language processing (NLP) is used to decide if an assignment is possible with a certain matching probability. The assigned test step definitions are used to generate graphical test models for the test scenarios, e.g. UML diagrams. Finally, executable test scripts are generated to test the software program. The present invention relates particularly to Behavior-Driven Development (BDD) and combines traditional BDD advantages with Model Based Testing (MBT) for improved convenience and automatization in case of complex software packages. The automated step matching allows an efficient mapping of BDD step phrases to a test automation framework and supports the structured development of the necessary framework code.
