摘要： Described herein are systems and methods for use with a load balancer or traffic director, and administration thereof, wherein the traffic director is provided as a software-based load balancer that can be used to deliver a fast, reliable, scalable, and secure platform for load-balancing Internet and other traffic to back-end origin servers, such as web servers, application servers, or other resource servers. In accordance with an embodiment, the system comprises a traffic director having one or more traffic director instances, which is configured to receive and communicate requests, from clients, to origin servers having one or more pools of servers. A health check subsystem periodically checks the health of its configured resource servers, and also attempts to detect changes in the one or more pools, by sending requests to any new server instances configured as origin servers within the pool, receiving appropriate responses, and updating the configuration accordingly.

摘要： An anomaly detector compares a first event from a business activity monitoring system to a second number from an independent trusted source, wherein the first event includes a first number. The anomaly detector determines that the first number from the business activity monitoring system is inconsistent with the second number. The anomaly detector generates a calibration relationship between first number and second number based on time, responsive to a determination that the first number is inconsistent with the second number. The anomaly detector stores the calibration relationship. The anomaly detector receives a third number from the business activity monitoring system at an interval after comparing the first number. The anomaly detector displays the third number to a dashboard. The anomaly detector displays a qualifier to the third number.

摘要： A session is established between a user system and an existing version of a network application. Once the session is established, session information corresponding to the session is determined and then communicated to the user system. The session information typically includes a version identifier that identifies the existing version of the network application. Requests received during the same session are accompanied with the session information. The session information is used to route the requests to the existing version of the network application.

摘要： A universal DMA (Direct Memory Access) engine can be dynamically configured to function in either a receive or transmit mode. DMAs are logically assembled and bound as needed, without limitation to a fixed, pre-determined number of receive engines and transmit engines. Because a DMA engine may be dynamically assembled to support the flow of data in either direction, varied usage models are enabled, and components used to assemble a receive DMA engine for one application may be subsequently used to assemble a transmit engine for a different application. An application may request a specific number of each type of engine, depending on the nature of its input/output traffic. The number of receive or transmit engines can be dynamically increased or decreased without suspending or rebooting the host. A universal DMA architecture provides a unified software framework, thereby decreasing the complexity of the software and the hardware gate count cost.

摘要： Some embodiments of the present invention provide a system for packet classification and spreading in a virtualized system. The system can use information in a packet's header to determine a destination system-image in the virtualized system, and a packet-spreading policy for the destination system-image. The system can determine a key using the information in a packet's header. Alternatively, the system can hash the information in the packet's header to obtain an index value. Next, the system can use the key or the index value to perform a lookup in a table which associates keys or index values with system images and/or packet-spreading policies. Once the destination system-image and the packet-spreading policy are determined, the system can deliver the packet to a thread on the destination system-image according to the packet-spreading policy.

摘要： A plasma ignition system is described herein that can produce plasma ionization around a spark plug gap using a single power circuit for the spark and plasma ionization. The system results in fewer components and higher reliability, allowing the system to be more easily integrated with existing ignition circuitry or in new ignition system designs. The plasma ignition system adds a one-way current path between the primary and secondary windings of the high voltage transformer. This allows energy stored within the capacitor after the creation of the spark to flow out of the capacitor, across the one-way current path, and through the spark plug gap. Thus, the plasma ignition system provides a dramatically better ignition spark with relatively little increase in components. The system does so without requiring a secondary power supply circuit to generate the current for producing plasma ionization.
