Abstract: Systems and methods for providing targeted event notifications to subscribers are disclosed. In an example embodiment, events may be received from a publisher. The events may be categorized into a plurality of topics. The events may be distributed among brokers to process a topic selected from the plurality of topics based on the events. Further, it may be determined whether the topic exists in a list of topics handled by the brokers. Authentication credentials of the publisher may be validated, based on the determination. Based on the validation, queues of the events may be formed based on an order of receipt of the events. The events present in the queues may be filtered based on subscriptions of the events. For the fileted events, targeted even notifications may be forwarded to the subscribers.

Abstract: Systems and methods for filtering and routing event notifications to subscribers are disclosed. In an example embodiment, events from a publisher may be received. Each of the events may be associated with a topic, and the topic may be compared with topics present in broker metadata cache, based on one of prefixes and a fast lookup technique using a hash-table. Further, it may be determined whether the topic associated the events is present in the broker metadata cache based on comparison. Based upon determining, matching nodes for the events may be retrieved. Further, the events may be routed based on routing tables and availability of the matching nodes. Based on the routing, the events may be forwarded to the subscribers.

Abstract: Systems and methods for dispatching targeted event notifications to subscribers are disclosed. In an embodiment, the system includes a receiver to receive events from a publisher. The system further comprises a router in communication with the receiver to route the events. The system further comprises a director to forward the targeted event notifications to the subscribers based on the routing. The director receives a delivery status of the targeted event notification from the subscribers. The delivery status includes one of success in receiving the targeted event notification and failure in receiving the targeted event notification. The director receives an event notification with the delivery status as failure in receiving the targeted event notification. The director places the targeted event notification in a delayed queue indicative of events to be delivered after a predefined time. The director re-transmits the targeted event notification to the subscribers based on the delayed queue.

Abstract: Systems and methods for dispatching targeted event notifications to subscribers are disclosed. In an example embodiment, a notification indicating creation of an even subscription by a subscriber may be received. An event source may be invoked to enable publishing of events corresponding to an event topic associated with the event subscription. A response from the event source for publishing of the events may be received and targeted event notifications may be forwarded to the subscribers on receiving the response.

Abstract: The present invention extends to methods, systems, and computer program products for using HyperText Transfer Protocol communication as a transport for bi-directional data streams. Embodiments of the invention facilitate passing otherwise blocked TCP communication through a firewall. Embodiments of the invention can be used to pass legitimate TCP communication through a firewall even though a firewall is configured to block the legitimate TCP communication.

Abstract: A common infrastructure for management and one way message routing can accommodate a set of related but conceptually different message delivery protocols. Junctions can be simultaneously created and configured at a location within a namespace. As a result, messaging related functionality can be more efficiently and uniformly added to a namespace. Additionally, embodiments include junctions that indicate roles and store behaviors and constraints for roles locally. Thus, computer systems desiring to utilize messaging related functionality can access the junction and utilize messaging related functionality provided at the junction without having to refer to other locations in a namespace (e.g., to perform lookups). Thus, resource and network bandwidth consumption associated with adding and utilizing messaging related functionality to a network infrastructure is reduced.
