Abstract: Systems and methods are provided that route messages for a message consumer to a predicted future connection point of the consumer to a messaging network, while the consumer is not connected to the messaging network. In various embodiments, the network predicts or projects the future connection point based on the consumer's last connection, an itinerary or schedule for the consumer, the consumer's past connection behavior, and/or connection patterns of the consumer and/or a group of message consumers that are similar to the consumer.

Abstract: Embodiments relate to routing a message only along routes in a messaging network that lead to a currently active consumer for the message. The messaging network adapts to changes in the message preferences of the message consumer, and the message consumer's availability throughout the messaging network. In various embodiments, changes to message routing criteria at a destination broker in the network are propagated to all other brokers in the network until the entire network is adapted, and the network routes messages based on the adaptations, which reflect the current connectivity and message accepting criteria of each message consumer.

Abstract: Systems and methods are disclosed that provide a single logical broker from the point of view of a message consumer connected to a messaging network. The messaging network implements dynamic routing that adapts to changes in the message preferences of the message consumer and the message consumer's availability throughout the messaging network. In various embodiments, the connection/disconnection of a message consumer and/or changes to message routing criteria at any broker in the network are propagated to all other brokers in the network until the entire network is adapted, such that a message consumer may connect to any broker node and receive the same network service and functionality regardless of connection point.

Abstract: Systems and methods are provided that dynamically route messages based on the availability of a message consumer on any given route, and which adapt to changes in message consumer availability throughout a messaging network. In various embodiments, changes to message routing criteria at a destination broker in the network are propagated to each source broker for the destination broker, which in turn propagates the changes to their source brokers until the entire network is adapted.

Abstract: A method and system for requesting an interrupt from a host system to service an adapter connected to the host system and a data interface. Data packets, including one or more data cells, are transferred between the data interface and the host system. The host system includes a host memory that includes a plurality of memory slots to store data packets transferred between the data interface and the host system. It is determined when a transfer of data has resulted in an occurrence of an interrupt event. An interrupt event occurs when the transfer of data includes a transfer of a data cell between the data interface and the host system and the data cell is defined to be an end of a data packet. In response to the occurrence of an interrupt event, it is determined whether to generate an interrupt request to the host system.

Abstract: A process and system for switching connections of data packet flows between nodes of data processing system networks operating on diverse protocols according to the application layer information on the data packets. The process retrieves and hashes the header information to from an index into memory where a flow tag pointer is stored. The flow tag points to flow switching information that directs the forwarding of the packet. The switching information is sent along with the packet data to direct the forwarding state information about the flow is updated in the flow switching information. The hash function includes a multiplication and division by polynomials forming a hash result and a signature result. Both hash and signature are used to ensure that the information retrieved is valid. If invalid, The pre hashed header information is parsed to determine the forwarding information. This forwarding information is stored for later use and the appropriate flow tag pointer is stored in the hash result index.

Abstract: A time-based and event-based interrupt frequency mitigation scheme is provided. A holdoff event counter is programmed to count a holdoff event count corresponding to a number of interrupts. A holdoff timer is programmed to time a holdoff interval representing the time period to elapse before the generation of an interrupt request to the host system can occur. When a data transfer request associated with the transfer of data from or to the host system is serviced and results in the occurrence of an interrupt event, the holdoff event counter is modified by one. If either the holdoff event counter or the holdoff timer has expired and the interrupt is enabled, an interrupt request to the host system is generated. In response to such interrupt request generation, the interrupt is processed and both the holdoff event counter and the holdoff timer retriggered.

Abstract: A mechanism by which interrupt frequency mitigation is combined with transmit raw cell status report frequency mitigation is presented. A tx raw cell status report is allowed to occur for only every N raw cell tx slots consumed. When the rate of interrupt requests is mitigated in accordance with holdoff parameters including a holdoff event count corresponding to X interrupt events and a holdoff time interval, and the raw cell status report counts as an interrupt event, an interrupt request is generated for an enabled interrupt if N*X events has occurred or the holdoff time interval has elapsed.
